Researchers have observed that plants, when stressed, can reprogram their cells into stem cells, capable of differentiating into many different cell types. Now, it appears mammals can perform the same trick. Japanese scientists say they have successfully reverted blood cells back to their embryonic state after dipping them in a stress-inducing bath of acid.

The team accomplished the feat using blood cells from mouse spleens, but are now trying to replicate it using human blood cells. Independent researchers are praising the discovery for both its simplicity and its potential to usher in new therapies and cloning techniques.

Scientists currently deploy one of two methods to obtain stem cells: extract them from human embryos, or reprogram adult cells into a stem-cell state (called induced pluripotent stem cells, or iPS cells). However, both methods have their drawbacks. Taking cells from an embryo destroys it in the process, and creating iPS cells requires a complicated choreography of genetic modifications.

The new method called STAP, for stimulus-triggered acquisition of pluripotency appears to be far easier. Chris Mason, a professor of regenerative medicine at University College of London, didnt mask his excitement for the BBC:

I thought my God thats a game changer! Its a very exciting, but surprise, finding If this works in people as well as it does in mice, it looks faster, cheaper and possibly safer than other cell reprogramming technologies personalized reprogrammed cell therapies may now be viable.

Haruko Obokata, the studys lead author, conceived of the idea after she noticed blood cells behaved peculiarly after squeezing them through a capillary tube. The cells would shrink to a size resembling stem cells. Intrigued, she replicated the technique by exposing blood cells to different types of stress. Three stressors perforating the cell membrane, exposure to an acidic solution, and physical squeezing caused the cells to behave like stem cells.

However, it was only the first step. Scientists needed to demonstrate that the transformed cells were truly pluripotent or capable of morphing into any type of cell.

To test that, scientists used mice bred to carry a gene that causes a protein in pluripotent cells to glow neon green. They injected the newly created stem cells into mouse embryos and the developing pups glowed all over, indicating that the embryos had successfully incorporated the stem cells into every tissue in their body. The team published their findings Wednesday in Nature.

Stressing blood cells harnesses a natural process, and could streamline the creation of stem cells. Jeff Karp, an associate professor at Brigham & Womens Hospital in Boston, told CNN the new method could produce stem cells up to 10 times faster than current methods.

New Method of Creating Stem Cells is a "Game Changer"

Stem cell breakthrough may be simple, fast, cheap

By adminJanuary 30, 2014Stem Cell Medicine

Researchers have developed a new method of making stem cells. Mouse cells were "stressed" in several ways, such as by being placed in an acidic environment. Researchers were then able to use those cells to generate various tissues in developing mice. This image shows a mouse fetus that has tissues that grew in part from the stem cells.

We run too hard, we fall down, were sick all of this puts stress on the cells in our bodies. But in whats being called a breakthrough in regenerative medicine, researchers have found a way to make stem cells by purposely putting mature cells under stress.

Two new studies published Wednesday in the journal Nature describe a method of taking mature cells from mice and turning them into embryonic-like stem cells, which can be coaxed into becoming any other kind of cell possible. One method effectively boils down to this: Put the cells in an acidic environment.

I think the process weve described mimics Mother Nature, said Dr. Charles Vacanti, director of the laboratory for Tissue Engineering and Regenerative Medicine at Brigham & Womens Hospital in Boston and senior author on one of the studies. Its a natural process that cells normally respond to.

Both studies represent a new step in the thriving science of stem cell research, which seeks to develop therapies to repair bodily damage and cure disease by being able to insert cells that can grow into whatever tissues or organs are needed. If you take an organ thats functioning at 10% of normal and bring it up to 25% functionality, that could greatly reduce the likelihood of fatality in that particular disease, Vacanti said.

This method by Vacanti and his colleagues is truly the simplest, cheapest, fastest method ever achieved for reprogramming [cells], said Jeff Karp, associate professor of medicine at the Brigham & Womens Hospital and principal faculty member at the Harvard Stem Cell Institute. He was not involved in the study.

Before the technique described in Nature, the leading candidates for creating stem cells artificially were those derived from embryos and stem cells from adult cells that require the insertion of DNA to become reprogrammable.

Stem cells are created the natural way every time an egg that is fertilized begins to divide. During the first four to five days of cell division, so-called pluripotent stem cells develop. They have the ability to turn into any cell in the body. Removing stem cells from the embryo destroys it, which is why this type of research is controversial.

Researchers have also developed a method of producing embryonic-like stem cells by taking a skin cell from a patient, for example, and adding a few bits of foreign DNA to reprogram the skin cell to become like an embryo and produce pluripotent cells, too. However, these cells are usually used for research because researchers do not want to give patients cells with extra DNA.

The new method does not involve the destruction of embryos or inserting new genetic material into cells, Vacanti said. It also avoids the problem of rejection: The body may reject stem cells that came from other people, but this method uses an individuals own mature cells.

Stanford stem cell genomics center funded

By adminJanuary 30, 2014Stem Cell Medicine

California's stem cell agency granted $40 million Wednesday to study how the use of stem cells for therapy is affected by variations in the human genome.

The Center of Excellence for Stem Cell Genomics will be located at Stanford University. Competing proposals, including one by DNA sequencing giant Illumina and The Scripps Research Institute in San Diego, were rejected by the California Institution for Regenerative Medicine.

Backers of the San Diego proposal said CIRM staff reviews of the proposals contained errors, such as including financial considerations when scientific merit was supposed to be the sole consideration. Stanford's proposal was highest-rated in the reviews.

The Stanford proposal earned praise from reviewers for the breadth of its research initiatives, from basic research to disease applications, along with the deep expertise of its scientists. Reviewers also liked the affiliated data management center, which will be located at UC Santa Cruz.

A number of San Diego research institutions will collaborate with Stanford's center. While the center itself will be placed at Stanford, the Salk Institute will participate as a joint principal investigator. The Scripps Research Institute and Illumina will also contribute, along with UC San Diego,and the J. Craig Venter Institute.

The Stanford proposal treats Illumina like a contractor, which doesnt make the best use of its abilities, said Scripps Research stem cell scientist Jeanne Loring, who attended the meeting. She submitted letters to the board from herself and Illumina explaining the project's benefits.

I was trying to tap into Illuminas intellectual power, which is often overlooked because they make most of their money by selling instruments and providing services, Loring said. But the people Id be working with are the ones who invented these technologies.

Illumina would benefit as a business by creating new markets, Loring said. For example, a test that tells whether stem cells have potentially dangerous mutations would be highly sought after.

Illumina pledged in a letter to CIRM that any products it sells under the agreement would be accessible, both in price and support.

Loring said she hopes the Scripps/Illumina proposal can still be funded, but there is no obvious alternative.

Stem cell researchers heralding ‘major scientific discovery’

PanARMENIAN.Net - Stem cell researchers are heralding a "major scientific discovery", with the potential to start a new age of personalized medicine, BBC News reports.

Scientists in Japan showed stem cells can now be made quickly just by dipping blood cells into acid.

Stem cells can transform into any tissue and are already being trialled for healing the eye, heart and brain.

The latest development, published in the journal Nature, could make the technology cheaper, faster and safer, according to the BBC.

The human body is built of cells with a specific role - nerve cells, liver cells, muscle cells - and that role is fixed. However, stem cells can become any other type of cell, and they have become a major field of research in medicine for their potential to regenerate the body.

Embryos are one, ethically charged, source of stem cells. Nobel prize winning research also showed that skin cells could be "genetically reprogrammed" to become stem cells (termed induced pluripotent stem cells).

Now a study shows that shocking blood cells with acid could also trigger the transformation into stem cells - this time termed STAP (stimulus-triggered acquisition of pluripotency) cells.

Dr Haruko Obokata, from the Riken Centre for Developmental Biology in Japan, said she was "really surprised" that cells could respond to their environment in this way.

She added: "It's exciting to think about the new possibilities these findings offer us, not only in regenerative medicine, but cancer as well."

Are Stem Cells The Cure To Baldness?

While a Chinese cream may not have cured George Costanzas baldness in a classic Seinfeld episode, stem cell research from scientists at the University of Pennsylvania has shown the potential for regenerating hair follicles which could lead to relief for hair-challenged men everywhere.

According to a new report published in the journal Nature Communications, the Pennsylvania researchers have developed a groundbreaking method for converting adult cells into epithelial stem cells (EpSCs). Similar previous efforts have failed to generate an adequate number of hair-follicle-generating stem cells.

In the study, epithelial stem cells were inserted into immunocompromised mice. The stem cells regenerated the various cell types for human skin and hair follicles, and provided structurally identifiable hair shafts, raising the possibility of hair regeneration in humans.

The study team began with human skin cells referred to as dermal fibroblasts. By incorporating three genes, they modified those cells into induced pluripotent stem cells (iPSCs), which have the capacity to differentiate into any cell types in the human body. Next, they modified the iPS cells into epithelial stem cells, commonly located at the base of hair follicles.

Starting with procedures other research groups had worked out to transfer iPSCs into skin cells, Xus team figured out that by carefully manipulating the timing of the cell growth factors, they could drive the iPSCs to produce large quantities of epithelial stem cells. This method was able to turn more than 25 percent of the iPSCs into epithelial stem cells within 18 days. Those cells were then purified based on the proteins they showed on their surfaces.

Comparison of the engineered cells with epithelial stem tissue obtained from hair follicles revealed the team succeeded in making the cells they set out to produce. After mixing all those cells with mouse follicular inductive dermal cells and attaching them onto the pores and skin of immunodeficient mice, the team was able to produce efficient outer layers of human skin tissue and follicles structurally similar to those generated by human hair.

This is the first time anyone has made scalable amounts of epithelial stem cells that are capable of generating the epithelial component of hair follicles, said study author Dr. Xiaowei George Xu, associate professor of pathology and laboratory medicine and dermatology at the university. He added that these cells could be used for healing, cosmetics and hair regeneration.

Xu cautioned that iPSC-derived epithelial stem cells are not yet ready for human subjects.

27/01/2014 - 09:35:51Back to Ireland Home

Stem cells for human use are to be made in a university lab in the first medical programme of its kind in Ireland.

Scientists behind the new facility at the National University of Ireland Galway will aim to produce adult cells to combat conditions like arthritis, heart disease and diabetes.

Stem cells created at the lab will be used in clinical trials following regulatory approval the first of which is to test their effects on critical limb ischemia, a common complication associated with diabetes which often results in amputation.

The cells, mesenchymal stem cells (MSCs), will undergo safety tests after being isolated from bone marrow from donors and grown in the laboratory to generate sufficient quantities.

The university said it will position it as a global player in regenerative medicine.

NUI Galways Centre for Cell Manufacturing Ireland is the first facility on the island of Ireland to receive a licence from the Irish Medicines Board to manufacture culture-expanded stem cells for human use.

And it is one of less than half a dozen in Europe authorised for the process.

President of NUI Galway Dr Jim Browne said: Developing Galways role as med-tech hub of global standing, the Centre for Cell Manufacturing Ireland captures NUI Galways commitment to bring bold ideas to life.

Innovation can bridge the gap between patient and provider and meet the needs of industry and the wider society in a balanced way.

It's been nothing but 100% improvement.It just continues to get better.Ive been avoiding doing stairways and I have to be real careful climbing in and out of equipment. I find myself being a lot more relaxed, not having the problems, not having the pain. I don't have the swelling in my knees that I used to have and it hasnt been waking me up at night. View my video testimonial here My name is Susan and Im 62 year old I just finished having my second PRP treatment and Im very, very happy with the results I can do all kinds of things I wasn't able to do beforeI believe my knee will continue to get better as the cartilage grows. Thank you! View my video testimonial here

Many thanks to the Stem MD team for giving me the use of my hands back, pain free! Professional, courteous and compassionate, describes this team of caring people. To anyone considering this procedure, I say you will be amazed and thankful at the results.

Lenita Brewer Ansonia, Ohio

Thank you for giving my life and health back. The PRP treatment worked wonders and helped alleviate the pain. I highly recommend the anti-inflammatory diet, Dr. Purita suggested. My body noticed the difference and I lost 35 pounds. I can finally be active again!

Jennica Califf Coconut Creek, Florida

I thought there was no hope for my chronic back pain. I am so thankful I found out about Dr. Purita and stem cells. I have had back pain for over 5 years, debilitating me to do everyday things. Today my pain has gone down 50%. I tell all my friends and family and wish everyone knew about this wonderful treatment. Thank you so much Dr. Purita

It has been 3 months since my mothers procedure to her knees. Now, my mom climbs into the van without any help, before we had to pull her up and assist her. She does not take painkillers anymore, even her recurring bladder infection and Diabetes is well controlled. All my friends and colleagues are super amazed every time I show them a video of my mom dancing. Thank you so much what you have done for my mom it is truly wonderful and I am forever indebted to you.

I came to Dr. Purita on the advice of a friend when I expressed trepidations about cortisone shots or the possibility no matter how remote of a joint replacement. I was a wrestler in high school and college, and this had done no good for my kneed as I aged. I had no expectations, only hope that somehow my knees could be made less fragile by the stem cell therapy my friend described. I had gotten to the point where any down stairs journey or stepping down off a van or public bus was excruciating, to the point that I usually made an exclamation that wasn't fit for public utterance every time I stepped off a bus or a van. My expectations were neutral at best. I had no idea as to how this stem cell therapy would impact my general health whatsoever. I can say without hesitation that the results have been beyond what I could have hoped. My knees are now cooperative to the point that sometimes I take the stairs down just because I can. I have resumed walking the stairs up and down at work, and I can say that I really don't think about anything I want to do where my kneed are involved. I am not quite where I was when I was 20, but 35 is a real thought, my flexibility and agility are restored to a level I could not have imagined. As an additional part of the procedure Dr. Purita also injected stem cell into my left hand, which has been diagnosed with some arthritis. The results are less instantaneously spectacular, but the had continues to improve. I no longer sit in my office while my hand burns with joint pain, my movement and most of my strength are improving daily, and I have a feeling that within a month or so I will have the same level of improvement I have experiences with my knees. Many thanks to the friend who recommended the trip to Dr. Purita's office, and to Dr. Purita and his staff who have put thoughts of joint replacement and the mad merry-go-round of cortisone shots far in the past for me.
