EDIT-301 is currently being investigated in a clinical study in patients with severe sickle cell disease (RUBY trial, NCT04853576) and transfusion-dependent beta thalassemia (EDITHAL trial, NCT05444894). In addition to the clinical data update from the RUBY trial at EHA and in a Company-sponsored webinar next month, the Company will present a further clinical update from the RUBY trial by year-end. Additionally, the Company is on-track to dose 20 patients in the RUBY trial by year-end.

About Sickle Cell DiseaseSickle cell disease is an inherited blood disorder caused by a mutation in the beta-globin gene that leads to polymerization of the sickle hemoglobin (HbS). In sickle cell disease, the red blood cells are misshapen in a sickle shape instead of a typical disc shape. The abnormal shape causes the red blood cells to have shortened lifespan and to block blood flow causing anemia, pain crises, organ failure, and early death. There are an estimated 100,000 people in the United States currently living with sickle cell disease. Higher levels of fetal hemoglobin (HbF) inhibit HbS polymerization, thus reducing the manifestation of sickling.

About EDIT-301EDIT-301 is an experimental cell therapy medicine under investigation for the treatment of severe sickle cell disease (SCD) and transfusion-dependent beta thalassemia (TDT). EDIT-301 consists of patient-derived CD34+ hematopoietic stem and progenitor cells edited at the gamma globin gene (HBG1 and HBG2) promoters, where naturally occurring fetal hemoglobin (HbF) inducing mutations reside, by a highly specific and efficient proprietary engineered AsCas12a nuclease. Red blood cells derived from EDIT-301 CD34+ cells demonstrate a sustained increase in fetal hemoglobin production, which has the potential to provide a one-time, durable treatment benefit for people living with severe SCD and TDT.

About RUBYThe RUBY trial is a single-arm, open-label, multi-center Phase 1/2 study designed to assess the safety and efficacy of EDIT-301 in patients with severe sickle cell disease. Enrolled patients will receive a single administration of EDIT-301. Additional details are available onwww.clinicaltrials.gov(NCT04853576).

Researchers solve mystery of how statins improve blood vessel health – Stanford Medical Center Report

ATAC-seq revealed that simvastatin-treated cells had closed chromatin structures that reduced the expression of genes that cause the endothelial-to-mesenchymal transition. Working backward, the researchers found that simvastatin prevents a protein known as YAP from entering the nucleus and opening chromatin.

The YAP protein is known to play important roles in development, such as regulating the size of our organs, but also has been implicated in the abnormal cell growth seen in cancer.

To see the drug in context, the researchers tested simvastatin on diabetic mice. Diabetes causes subtle changes to blood vessels that mimic the damage commonly seen in people who are prescribed statins older patients who do not have a cardiovascular condition, Liu said.

They found that after eight weeks on simvastatin, the diabetic mice had significantly improved vascular function, with arteries that more easily relaxed and contracted.

If we can understand the mechanism, we can fine-tune this drug to be more specific to rescuing vascular function, Liu said.

The findings also provide a more detailed picture of the vascular disease process, which could help doctors identify and treat early signs of vascular damage.

Ive been taking statins for the past 10 years to keep my cholesterol down. I also knew it has good vascular effects. I just didnt know how it does it, said Wu, the Simon H. Stertzer, MD, Professor who is also the director of the Stanford Cardiovascular Institute. This study explains how.

Researchers from the University of North Texas and the Ohio State University College of Medicine contributed to this study.

The study was supported by funding from the National Institutes of Health (grants R01 HL130020, R01 HL150693, R01 HL163680, R01 HL145676, P01 HL141084, R01 HL141371, R01 HL126527, R01 HL15864, R01 HL161002, R01 HL155282 and 18CDA34110293), an American Heart Association SFRN grant, an AHA Career Development Award and the Tobacco-Related Disease Research Program.

What’s Exosome Therapy And How Can It Help Your Skin & Hair? – Glam

As you age, your skin's collagen production isn't the only thing that slows down. Your hair follicles do, too, with some growing out considerably thinner hair and others ending the hair growth cycle altogether. In addition, sebum production also reduces as you age, leading to duller, lustreless hair.The drop in hair growth and thickness eventually leads to permanent hair loss. But of course, there are other causative factors of hair loss, such as genetics, medications, and stress.

When fed into the follicles and scalp, exosomes reawaken the follicular cells, jumpstarting them and fostering hair growth. The therapy also helps prolong the anagen phase of the hair growth cycle and decrease or delay the catagen phase. Anagen is the growth phase, while catagen is the phase where hair growth stops. By prolonging the anagen phase, the follicles have more time to produce hair and combat hair loss. With their wound-healing and anti-inflammatory properties, exosomes can also help repair damaged tissues and follicles in the scalp. And everyone knows that healthy follicles equal healthy strands.

You can have more than one exosome session to reap the full benefits. However, waiting 3 to 6 months between sessions is preferred to evaluate if more sessions are necessary.Now that you know the benefits of exosome therapy for your skin and hair, we're sure you're wondering about the procedure. Well, here's what you need to know pre- and post-procedure.

Thalassemia gene therapy approval marks a new era of treatment – Labiotech.eu

A newly-approved gene therapy is transforming the lives of patients with beta thalassemia an inherited blood disorder by helping to stop or significantly reduce their reliance on blood transfusions, says an expert from a leading global health system, Cleveland Clinic, on International Thalassemia Day on May 8.

A gene therapy known as betibeglogene autotemcel, or beti-cel, was approved in August last year by the US Food and Drug Administration (FDA) as safe and efficacious for adult and pediatric patients with transfusion-dependent beta thalassemia.

Rabi Hanna, a pediatric hematologist-oncologist at Cleveland Clinic Childrens which is in the process of becoming one of the few centers in the world certified to offer the gene therapy said: This is a milestone in thalassemia treatment as gene therapy uses patients own hematopoietic stem cells to produce healthier red blood cells and cure their blood disorder or at the very least, significantly reduce the number of blood transfusions needed to manage their condition. Thanks to gene therapy, we can remove the challenges that thalassemia patients face and give them the potential to pursue their goals and dreams without the restriction of blood transfusion or complications of iron overload.

Thalassemia, which has two types alpha and beta is among the most common genetic disorders and occurs most frequently in people from the Middle East, Mediterranean countries, North Africa, India, Central Asia, and Southeast Asia.

Beta thalassemia affects the bodys ability to produce hemoglobin, a protein in red blood cells that allows them to transport oxygen throughout the body. Individuals diagnosed with beta thalassemia major develop serious symptoms at a young age, which can be treated with frequent blood transfusions, but the transfusions themselves create the risk of iron overload with the potential to damage patients liver, heart, and endocrine system.

The new gene therapy, which resolves this problem, is ideal for teenagers or slightly older patients who have already started to experience complications from blood transfusions, Hanna said.

Hanna said: The gene therapy includes a short period (four days) of a chemotherapy called busulfan that may impact on male and female patients fertility, so it is better to wait until patients reach their teenage years so that they can undergo fertility-preservation treatment, although we do have methods to preserve fertility even in pre-pubescent patients. On the other hand, it is best not to leave it too long as after years of infusions, patients hearts and livers may have already been severely impaired from iron overload. Generally, the healthier the patients are at the start of the gene therapy process, the fewer side effects they will have.

The minimally invasive beti-cel treatment is delivered in three phases over several months, Hanna said. In the first phase, two medications (G-CSF and plerixafor) are used to stimulate the patients bone marrow to produce more stem cells. In the second, blood is drawn for stem cell collection from peripheral blood, and these stem cells are sent to the treatment company to perform the gene modification, that is, inserting a gene that enables them to produce non-affected hemoglobin. The modification process takes around two months.

The final phase takes place in a hospital so patients can be closely monitored. They receive a single chemotherapy medication once a day for four days, followed by a few days of rest, to prepare the body for the modified stem cells to be reintroduced through infusion into a vein, similar to an IV drip.

Within about a month after the infusion of the modified cells, Hanna noted, the vast majority of patients will engraft with the new stem cells and will not need any more blood transfusions or other treatments as they will have cells established in their bone marrow capable of producing hemoglobin normally. Even in the few exceptional cases where gene therapy is not curative, patients need for blood transfusions will have been reduced substantially.

Aside from the new gene therapy treatment, other advances in recent years have greatly improved the quality of life for thalassemia patients, Hanna said.

A medication with the generic name luspatercept-aamt was approved by the FDA in 2019 to reduce patients reliance on blood transfusions. It is given in the form of an injection every three weeks and works by enhancing erythroid (red blood cell) maturation and reducing the need for blood transfusions by up to 50% in some patients.

Luspatercept-aamt can also be used to enhance outcomes in curative bone marrow transplantations, which have become more widely accessible in recent years thanks to a new transplant approach. Hanna was among the pioneers of the haplo-identical bone marrow transplant, which allows for non-identical-HLA (human leukocyte antigen) donors.

Hanna said the reduction in blood transfusions enabled by luspatercept-aamt means the patient has better health prior to bone marrow transplants, and fewer antibodies that could potentially attack transplanted bone marrow.

With the wider adoption of gene therapy and the use of luspatercept-aamt to improve bone-marrow transplant outcomes, almost any patient can be cured, Hanna said.

About exagamglogene autotemcel (exa-cel)Exa-cel, formerly known as CTX001, is an investigational, autologous,ex vivoCRISPR/Cas9 gene-edited therapy that is being evaluated for patients with TDT or SCD characterized by recurrent vaso-occlusive crises (VOCs), in which a patients own hematopoietic stem cells are edited to produce high levels of fetal hemoglobin (HbF; hemoglobin F) in red blood cells. HbF is the form of the oxygen-carrying hemoglobin that is naturally present during fetal development, which then switches to the adult form of hemoglobin after birth. The elevation of HbF by exa-cel has the potential to alleviate transfusion requirements for patients with TDT and reduce painful and debilitating sickle crises for patients with SCD. Earlier results from these ongoing trials were published inThe New England Journal of Medicinein January of 2021.

Based on progress in this program to date, exa-cel has been granted Regenerative Medicine Advanced Therapy (RMAT), Fast Track, Orphan Drug, and Rare Pediatric Disease designations from theFDA for both TDT and SCD. Exa-cel has also been granted Orphan Drug Designation from theEuropean Commission, as well as Priority Medicines (PRIME) designation from theEuropean Medicines Agency(EMA), for both TDT and SCD. In the U.K., exa-cel has been granted an Innovation Passport under the Innovative Licensing and Access Pathway (ILAP) from the MHRA.

Board of Regents medals awarded for teaching excellence … – University of Hawaii

The Regents Medal for Excellence in Teaching is awarded by the Board of Regents as tribute to faculty members who exhibit an extraordinary level of subject mastery and scholarship, teaching effectiveness and creativity and personal values that benefit students.

Rosanna Alegado is an associate professor of oceanography in the University of Hawaii at Mnoa School of Ocean and Earth Science and Technology (SOEST). Her work involves meaningful academic collaborations and partnerships with Indigenous communities.

She led SOESTs significant curriculum revision toward a required immersive course to ground all incoming graduate students in an understanding of working as marine biologists within Hawaiian culture. Its success has been recognized by the National Science Foundation with multi-year funding to foreground Indigenous knowledge, practices and values, and to transform and Indigenize higher education in STEM.

Alegado is regarded as an influential educator for other teaching faculty, as well as her students. She said, By challenging my students to integrate multiple didactic frameworks, one can achieve the most comprehensive understanding of a subject.

Her colleagues say that Rosie is not popular by being easy, and that her efforts are the epitome of teaching exceptionalism.

Tammy Hailipua Baker is an associate professor of theatre and dance in the University of Hawaii at Mnoa College of Arts, Languages & Letters. As a steward of Indigenous knowledge, she fulfilled that kuleana (responsibility) by building the Hawaiian Theatre Program, the only one of its kind focused primarily on performance.

A colleague, who was also her student in Hawaiian language, views the experience of acting in her productions as a master class in pedagogy. Professor Baker is continually supporting students and others in the production of 40 performers in speaking and singing lines individually and collectively. [She was] clearly the director throughout, nevertheless each actor (students) and production staff (teachers) were all made to feel their work was necessary and appreciated.

Baker is internationally recognized, the first from Hawaii to receive the Kennedy Centers Medallion of Excellence. A reviewer of her plays describes them as guides to restoring language and reclaiming the stories of generations of Indigenous populations; gifts to a culture whose language and history have been suppressed. Her transformative work shines through the passion, voice and aloha spirit of her students.

Richard C. Chen is an associate professor at the William S. Richardson School of Law at the University of Hawaii at Mnoa. He brings patience and empathy to all his interactions with students, never assuming the problem is with the students. This tenet is a teaching practice that extends into a way of modeling for the students as they enter the profession of law, as lawyers who seek to listen, learn and improve throughout their careers.

A cohort of 19 evening students for four straight semesters signed an enthusiastic letter of support for Chen, stating they collectively hope that our endorsement can begin to illuminate our appreciation of his talents as an educator and the positive impact he made during the formative stages of our legal education.

A colleague stated, Who wouldnt want to be in his classes? He is a professor whose empathy, kindness, brilliance and skill shine through in everything he does and it is elevating, inspirational and contagious.

Advances in Cell Therapy – Technology Networks

Several cell therapies are now approved for treating human disease and many more are being developed. In this article, we review the latest research in cell therapy development, including advances made in the lab that show promise for translation to the clinic, to improvements in developing, testing and manufacturing.

Cell therapy is the transfer of cells into a patient, either cells from the patient themselves (autologous) or from a donor (allogeneic), for therapeutic purposes. Researchers have been attempting to use cells as treatments for hundreds of years, but for several decades, the only successful application was the use of bone marrow transplantation for leukemia.1 Today, key advances in understanding and genetic engineering of stem- and non-stem (somatic) cells have led to a series of cell therapy approvals. The first stem cell therapy was approved in 2014 for a rare condition called severe limbal stem cell deficiency (LSCD) caused by burns to the eye,2 and in 2017, the first chimeric antigen receptor (CAR) T-cell treatment, Kymriah (tisagenlecleucel), was approved for children and young adults with B-cell leukemia.3

Following these authorizations, the global market for cell-based therapies was valued at USD 21.6 billion in 2022 and is expected to expand to USD 62.4 billion in 2030.4 Although the largest market share is oncology, cell therapies are being explored for a wide range of other indications including central nervous system (CNS) and neurodegenerative diseases, autoimmune disease, cardiovascular disease and rare, orphan diseases.1

Cell therapies are either based on stem or somatic cells. In this article, we explore some examples highlighting both approaches, and the challenges of translating their promise in the clinic.

One of the fastest-moving areas of cell therapy is the development of CAR T cells in oncology. In this approach, T cells collected from patients or donors are engineered to express a chimeric antigen receptor that recognizes unique tumor antigens, grown in large numbers, and then administered back to patients. Despite the excitement in the field since the first approvals, there remain considerable challenges. These include the difficulty of reproducing the success seen in hematological cancers to solid tumors, and optimizing patient response in terms of the amount and duration of anti-tumor immunity. 1

For a long time, a major challenge for many of these therapies was manufacturing the cells, says David Zhang, a member of the Mooney lab at the Wyss Institute for Biologically Inspired Engineering, Harvard University. Then people figured out better ways of making lots of CAR T cells from a process perspective, with different bioreactor systems and other technological advancements. However, although it became possible to make large numbers of T cells from patient samples, there was still huge variation in individual patient responses to treatment. This led to retrospective analyses of attributes of the cells and factors during the manufacturing process that influence patient response. But the one thing that no one seemed to be looking at was how to optimize the way the T cells were getting activated in the first place, says Zhang. We knew that how we activated the cells was really important to the response we got, so we developed a system to fine tune activation parameters, and see how this affected their function.

The system is designed to mimic the function of the T-cell zone in human lymph nodes, by comprising biodegradable mesoporous silica rods that can be loaded with immune-stimulatory molecules called cytokines. The rods are coated with a lipid bilayer, to which you can attach different activating antibodies. T cells require three signals to be able to proliferate and differentiate: a T-cell receptor stimulation signal, costimulatory signals and a mitogenic growth signal, says Zhang. Our system allows T cells to naturally rearrange the artificial membranes to form an immunological synapse while supporting paracrine signaling, mimicking two important parts of physiological T-cell activation.

Zhang used this system to fine tune all the different parameters that could influence the ultimate T-cell product. But the one thing that really influenced the resulting cell phenotype and function was changing the amount or dose of T-cell stimulation the cells received.

We found that theres a quantitative relationship between your starting cell population, the amount of stimulation you provide, and the phenotype and function of the CAR T cells, says Zhang. We were able to fine-tune the levels of T-cell stimulation to match different phenotypes of the T cells obtained from patients with leukemia, which allowed us to produce CAR T cells with significantly enhanced tumor-clearing activity in a patient-specific manner.

The team used a simple machine learning model to find a pattern between these parameters, which Zhang says can easily be adapted to any starting cell population and any desired CAR T product characteristics, such as enhanced tumor memory, rapid proliferation or a durable response.5 This means that it becomes possible to fine-tune the product based on the patients original T-cell sample.

Given that T-cell samples are always phenotyped, and sometimes genotyped, at the start of manufacturing, similar strategies could be used to personalize the therapy using our approach, says Zhang. It means you can start with one donor sample, and potentially generate, for example, three different CAR T products that are better for different use cases or even different stages of the disease.

Active cell therapy drugs represent the latest in cancer treatment. Of these, chimeric antigen receptor (CAR) cell modalities are considered the most successful.Download this whitepaper to learn more about robust and reproducible methods for CAR expression detection, choosing the best reagents for your assay requirements, and next-generation CAR constructs and the future of cancer treatment.

An alternative to harvesting mature cells like T cells is to differentiate or engineer immature stem cells into your desired cell therapeutic product. One of the most active areas of research using this approach is in restoring or protecting the function of nerve cells. In Justin Ichidas lab at the University of Southern California, they are growing stem cells into different types of nerve cells to be used as treatments and for screening drugs. One of their projects, in collaboration with Jon-Paul Pepper, a specialist in facial reconstructive surgery, aimed to help people who sustained facial nerve injuries after an accident.6 These injuries often affect motor neurons in the face muscles, and although the nerve can regenerate it does so very slowly, by the time the muscle has already atrophied, explains Ichida. Because we can grow motor neurons from stem cells, we thought perhaps these cultivated cells could babysit the muscle, until the real nerve regenerates. To test this, they cut the sciatic nerve in mice and introduced motor neurons grown from induced pluripotent stem cells. The home-grown stem cells successfully extended their axons and innervated the muscle. After a couple of months, you could see there was a huge difference in preserved muscle mass, whereas the leg muscles in mice that did not receive the motor neuron therapy, completely atrophied away, says Ichida. What was really interesting, is that the nerve cells didnt require any additional stimulation to innervate the muscle in the way that a natural nerve would do.

Now, Ichida is turning his attention to another type of cell that can be derived from pluripotent stem cells, called microglia. There is growing evidence that microglia, which are the primary immune cells in the brain, play a critical role in the duration and progression of neurodegenerative diseases such as motor neuron disease (also known as amyotrophic lateral sclerosis; ALS).7 We studied stem cells derived from patients with C9orf72 ALS, the most common form, and found a neuroprotective population of microglia, says Ichida.

Although many of the microglial cells that we derived from patients are actually neurotoxic, we found that when they were grown in close proximity to a C9orf72 motor neuron, they switch into a protective state. These protective microglia do exist in the brains of ALS patients, but they are in the minority. Having made this discovery, Ichidas team transplanted the protective microglia into mice harboring a mutation that causes ALS and identified the signaling pathway that switches the microglia from a neurotoxic to a neuroprotective state. Now, they plan to engineer the cells to lock them into a neuroprotective state so they can be transplanted into patients. One hurdle is to see whether stem cells can be transplanted into the human brain, says Ichida. Its been recently shown in rodents that you can transplant microglia and that the grafts extend broadly throughout the brain, so we have some proof of concept already there.

Further proof of concept comes from another study where engineered stem cells were transplanted into the CNS and showed early clinical promise. In the first clinical trial of its kind, a team of investigators from Cedars-Sinai Medical Center demonstrated that it was possible to deliver a combined stem cell and gene therapy into the spinal cord of patients with ALS.8 The stem cells produce a protein called glial cell line-derived neurotrophic factor (GDNF) which can promote the survival of motor neurons. The trial has proved the short-term safety of the approach, and now larger numbers of patients are needed to test its efficacy.

The key in ALS, and its very similar in Parkinsons disease and Alzheimers disease, is that these are very genetically diverse diseases, and so for most patients we dont have a full understanding of the genetic causes behind each persons condition, says Ichida. What we can do is take these patients stem cells and remake their neurons in a dish. Then, because these neurons in the lab mimic the same disease process in the patient, we can reprogram them, or we can use them to test new drugs that will work. In this way, were going to find treatments that are more likely to work across the whole breadth of the ALS population.

Restoring vision through retinal ganglion cell repopulation – Ophthalmology Times Europe

Ophthalmology is pioneering the field with clinical trials of stem cellderived retinal pigment epithelium and photoreceptor transplantation to potentially restore vision in diseases such as age-related macular degeneration and macular dystrophies. (Image credit freshidea / stock.adobe.com)

Ophthalmologists are all too familiar with the heartbreak that accompanies a new diagnosis of advanced optic neuropathy and the inability to offer patients treatment that can restore their vision. The unifying feature of all optic neuropathies is the death of retinal ganglion cells (RGCs), which are the projection neurons that transmit visual information from the retina to the brain via axons running through the optic nerve. Optic nerve diseases are both prevalent and irreversible; glaucoma alone affects more than 80 million individuals worldwide.

RGCs are central nervous system neurons and, like brain and spinal cord neurons, are not spontaneously regenerated following injury or insult in mammals. However, regenerative medicine advances are opening new pathways to restoring function in historically incurable neurodegenerative diseases, and ophthalmology is pioneering the field with clinical trials of stem cellderived retinal pigment epithelium and photoreceptor transplantation to potentially restore vision in diseases such as age-related macular degeneration and macular dystrophies.

Unfortunately, RGC replacement represents a more formidable challenge. Unlike photoreceptors, which comprise only four major subtypes, are intrinsically light responsive and make only a single synaptic connection to an adjacent retinal bipolar cell, RGCs are much more complex. Primates possess more than a dozen molecularly, functionally and topographically unique subtypes of RGCs that receive afferent input from complex inner retinal circuits that can include dozens of presynaptic bipolar and amacrine cells, and that must extend lengthy axons through the optic nerve and into one of several visual centres in the brain.

The list of challenges in making functional RGC replacement a reality is daunting and will require therapeutic manipulation of cellular pathways involving neuronal survival, migration, dendritogenesis and axogenesis, pathfinding, synaptogenesis and myelination. However, there is reason to be hopeful. Although the concept of optic nerve regeneration has long been the subject of fantasy, recent advances in neuroscience have converged to a point where functional RGC replacement may now be feasible.

Generation of new RGCs

The generation of induced pluripotent stem cells (iPSCs) from individual patients is now commonplace. By obtaining a skin biopsy, blood sample, or even urine specimen, it is possible to create patient-specific cell lines capable of nearly infinite expansion and to differentiate those iPSCs into a variety of specialised cells that are lost in various disease states. Indeed, scientists have developed several methodologies to create immature RGCs or even entire neural retinas (retinal organoids) from stem cells.

These advances have provided the tools necessary to begin preclinical experimentation in transplanting new RGCs into eyes with optic neuropathy. Separately, investigators have made significant advances in understanding the molecular pathways that enable lower vertebrates, like teleost fish, to regenerate their optic nerves following injury. By activating several proregenerative genes in the retinal Mller glia of adult mice, investigators have successfully coaxed these cells to proliferate and then transdifferentiate into RGC-like cells. Therefore, viable techniques to regenerate RGCs from both exogenous and intrinsic sources are available.

Integration into the retina

Placing new RGCs into the diseased retina is only the first step in functional vision restoration. Once present, RGCs must elaborate dendrites within the inner plexiform layer (IPL) and generate synapses with bipolar and amacrine cells to receive visual information that will be processed and relayed to the brain. Recent work in our laboratory has demonstrated that this does not occur spontaneously after RGCs are transplanted into the eye.

The internal limiting membrane (ILM; the basement membrane that separates the neural retina from the vitreous cavity) constitutes a barrier to the retinal transit of drugs and gene vectors, and we have shown that the ILM also inhibits the retinal integration of RGCs introduced into the vitreous cavity. By disrupting the ILM, we have been able to achieve not only migration of transplanted RGCs into the neuroanatomically relevant layer of the retina but also extension of dendrites into the IPL, where synaptogenesis can occur.

Because removal of the ILM through surgical peeling is an established technique used to treat macular holes and other vitreoretinal disorders in human patients, this finding provides a directly translatable approach to achieving retinal engraftment of transplanted neurons. Research is now poised to leverage synergy between RGC transplantation approaches and recent advances in neuroprotection to achieve greater and more widespread survival of donor RGCs across the retina, and to begin promoting dendrite extension and patterning, synaptogenesis, and integration into specific inner retinal circuits.

Eye-brain connectivity

Perhaps the most arduous challenge to RGC replacement will be promoting and guiding donor RGC axons from the retina to relevant visual processing centres in the brain, such as the lateral geniculate nucleus. Fortunately, great strides in the neuroregeneration field have been made in this area over the past 15 years. By studying endogenous RGCs injured by direct optic nerve trauma, investigators have identified several molecular pathways that can be modulated to unleash a latent regenerative capacity of mammalian RGCs. With therapeutic manipulation, mouse RGCs can regenerate axons for several millimeters past the site of an optic nerve crush.

Although many regenerating axons meander in a random fashionsometimes growing into ectopic locations such as the contralateral optic nervein some instances, these axons reach relevant visual centres in the brain and even restore rudimentary visually guided behaviors. Ongoing work to provide chemotactic guidance cues is increasing the efficiency of targeted axon regeneration, and applying these techniques to repopulated RGCs provides a promising means to regenerate the optic nerve de novoin cases of advanced optic neuropathy.

Efforts toward RGC repopulation

Although significant headway has been made to generate, protect, enhance or regenerate portions of RGCs in specific model systems, a lot of work clearly remains before a comprehensive treatment paradigm will be capable of replacing RGCs throughout the entirety of their contribution to the visual pathway. A pressing challenge is to begin consolidating the most efficacious approaches to each step of the RGC replacement process into a unified approach. Stem cell biologists are engineering RGCs with enhanced survival and integration capacity. Developmental biologists are detailing the molecular cues that drive patterning of RGC connectivity in the retina and the brain.

Cellular neuroscientists are curating the specific transcriptional and wiring patterns of RGCs and their changes in optic neuropathic disease states. Biomedical engineers are developing methods for transplanting delicate neurons on protective scaffolds and providing long-term trophic support and guidance cues to grafted cells.

Given the complexity of the task at hand, collaborative efforts among scientists with diverse expertise will be necessary to generate clinically viable methods for RGC repopulation. A group of leading investigators in the fields of ophthalmology and neuroscience has organised the Retinal ganglion cell (RGC) Repopulation, Stem cell Transplantation, and Optic nerve Regeneration consortium, which is bringing together more than 200 investigators worldwide. By fostering in-depth discussions regarding the most important obstacles to be overcome and organizing sustained collaborative research endeavors, we hope major headway will be made in the coming years to bring RGC repopulation toward the stage of clinical trial.

Infirmary Health has announced that, through an ongoing partnership with LifeSouth Community Blood Centers, CD-34 cells (stem cells) collected from umbilical cord blood, including those collected by Megan Dimoff, M.D., at Thomas Hospital, will soon travel to the International Space Station.

LifeSouth was selected to provide these cells to Abba Zubair, M.D., Ph.D., of the Mayo Clinic for his research study aboard the Space Station. Dr. Zubair and others are studying how these stem cells will divide or expand in space versus how the same cells expand on Earth, with the ultimate goal that these cells will be used for cancer treatment.

At Infirmary Health, our mission is LIFE. We are honored to fulfill our commitment to our mission through this unique opportunity granted to Thomas Hospital and Dr. Dimoff by Dr. Zubair and his team. We are incredibly proud of Dr. Dimoff, her representation of Thomas Hospital and her passion for advancing the practice of medicine., said Ormand Thompson, president of Thomas Hospital.

LifeSouths Cord Blood Bank provides products used for this study. At Thomas Hospital and Mobile Infirmary, mothers can donate their newborns umbilical cord blood, which is made available for patients needing a stem cell transplant. If the cord blood is not viable for transplant, it can be used for medical research aimed at curing cancers, diseases and genetic disorders.

A spacecraft is scheduled to launch this month from Kennedy Space Center and will carry these cryogenically-preserved cells to the International Space Station. Crew members on board will thaw the cells and seed them into specialized hardware to allow them to expand.
