UNC Hospitals preps for triple-tandem stem cell transplant

By Stem Cell Treatment

CHAPEL HILL, N.C. --

A Carrboro man is getting the first triple-tandem stem cell transplant performed at UNC Hospitals to treat a testicular cancer recurrence.

David Alston was diagnosed with testicular cancer a year ago. He went through chemotherapy at UNC and thought he'd beat it, but doctors discovered the cancerhad come back during a routine blood test.

"I was devastated", said Alston. "I completely fell apart."

He found hope again when Dr. Paul Armstead at UNC Hospitalssuggested a treatment that involved stem cell transplants.

"It's good for someone young like David whose already tolerated all the chemotherapy we've given him," said Dr. Armstead. "We think this is his best chance of being cured of this disease."

Alston's stem cells were recovered in a process that Alston says is like giving blood.

"Once we give a high dose of chemotherapy we then take some of his frozen bone marrow stem cells and give those back to him," explained Dr. Armstead. "This allows his blood count to recover and that's transplant number one."

Alston's treatment is unique because he'll receive three transplants. It's a process that will keep him in the hospital for about nine weeks and take a major toll on his immune system.

"I'm nervous because I know there's going to be a point where I just feel terrible," said Alston.

Northwestern University scientists have developed a powerful analytical method that they have used to direct stem cell differentiation. Out of millions of possibilities, they rapidly identified the chemical and physical structures that can cue stem cells to become osteocytes, cells found in mature bone.

Researchers can use the method, called nanocombinatorics, to build enormous libraries of physical structures varying in size from a few nanometers to many micrometers for addressing problems within and outside biology.

Those in the fields of chemistry, materials engineering and nanotechnology could use this invaluable tool to assess which chemical and physical structures -- including size, shape and composition -- work best for a desired process or function.

Nanocombinatorics holds promise for screening catalysts for energy conversion, understanding properties conferred by nanostructures, identifying active molecules for drug discovery or even optimizing materials for tissue regeneration, among other applications.

Details of the method and proof of concept is published in the Proceedings of the National Academy of Sciences.

"With further development, researchers might be able to use this approach to prepare cells of any lineage on command," said Chad A. Mirkin, who led the work. "Insight into such a process is important for understanding cancer development and for developing novel cancer treatment methodologies."

Mirkin is the George B. Rathmann Professor of Chemistry in the Weinberg College of Arts and Sciences and professor of medicine, chemical and biological engineering, biomedical engineering and materials science and engineering. He also is the director of Northwestern's International Institute for Nanotechnology (IIN).

The new analytical method utilizes a technique invented at Northwestern called polymer pen lithography, where basically a rubber stamp having as many as 11 million sharp pyramids is mounted on a transparent glass backing and precisely controlled by an atomic force microscope to generate desired patterns on a surface. Each pyramid -- a polymeric pen -- is coated with molecules for a particular purpose.

Each pyramid -- a polymeric pen -- is coated with molecules for a particular purpose.

In this work, the researchers used molecules that bind proteins found in the natural cell environment, such as fibronectin, which could then be attached onto a substrate in various patterns. (Fibronectin is a protein that mediates cell adhesion.) The team rapidly prepared millions of textured features over a large area, which they call a library. The library consisted of approximately 10,000 fibronectin patterns having as many as 25 million features ranging in size from a couple hundred nanometers to several micrometers.

To make these surfaces, they intentionally tilt the stamp and its array of pens as the stamp is brought down onto the substrate, each pen delivering a spot of molecules that could then bind fibronectin. The tilt results in different amounts of pressure on the polymeric pens, which dictates the feature size of each spot. Because the pressure varies across a broad range, so does the feature size.

Tonsils make T-cells, too

By Stem Cell Medical Center

ScienceDaily (Mar. 5, 2012) A new study provides evidence that a critical type of immune cell can develop in human tonsils. The cells, called T lymphocytes, or T cells, have been thought to develop only in the thymus, an organ of the immune system that sits on the heart.

The study, led by researchers at the Ohio State University Comprehensive Cancer Center -- Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC -- James), could improve the understanding of T-cell cancers and autoimmune diseases, and how stem-cell transplantation is done.

The study identified T cells at five distinct stages of development in the tonsil. These stages, identified using molecular signposts on the cells, were very similar to the stages of T-cell development in the thymus, although some differences were found as well.

The study also discovered that the cells develop in a particular region of the tonsil, in areas near the fibrous scaffold of the tonsil.

The findings are published in the Journal of Clinical Investigation.

"We've known for a long time that a functional thymus is necessary to develop a complete repertoire of T-cells, but whether a T-cell factory existed outside the thymus has been controversial," says principal investigator Dr. Michael A. Caligiuri, director of Ohio State's Comprehensive Cancer Center and CEO of the James Cancer Hospital and Solove Research Institute.

"I believe our study answers that question. It is the first report to describe a comprehensive, stepwise model for T-cell development outside the thymus."

It also raises a number of questions. Caligiuri notes that it's still unclear whether T-cells that develop in the tonsil also mature there or whether they leave the tonsil to mature elsewhere.

"The complete implications of this phenomenon for human health and disease are not entirely known," adds first-author Susan McClory, a graduate fellow in Caligiuri's laboratory. "It could be important in the development of T-cell cancers and autoimmune diseases, or it might suggest a location for T-cell development when thymus function is poor. We hope to do additional studies to explore these possibilities," she says.

Caligiuri, McClory and their colleagues conducted the study using tonsil tissue obtained from children undergoing routine tonsillectomy at Nationwide Children's Hospital in Columbus, and thymic tissue obtained from children undergoing thoracic surgery.

Histogen Signs License Agreement with Suneva Medical for Cell Conditioned Media-based Aesthetic Products

By Uncategorized

SAN DIEGO, March 5, 2012 /PRNewswire/ --Histogen Inc., a regenerative medicine company, and Suneva Medical, a privately-held aesthetics company, today announced that they have entered into a license agreement for physician-dispensed aesthetic products containing Histogen's proprietary multipotent cell conditioned media (CCM).

Under the terms of this license agreement, Suneva Medical has acquired exclusive U.S. licensing rights to Histogen's multipotent CCM and the ReGenica branded line of products for topical applications in the licensed market. Suneva Medical will manufacture the ReGenica product line and market it to aesthetic practitioners throughout the U.S. Histogen will receive a transfer price on the CCM, as well as royalties on future sales of ReGenica and product line extensions.

"First, let me say that, as the first step in expanding our business, we are very excited about this particular opportunity as the advent of regenerative medicine is upon us. One of our key business objectives is to find novel products that complement our rapidly growing dermal filler business. We believe Histogen's innovative technology coupled with our proven experience of developing and marketing aesthetic products is a winning combination as it enables us to offer our customers a differentiated product line," stated Nicholas Teti, Chairman and Chief Executive Officer of Suneva Medical.

Through Histogen's technology process, which mimics the embryonic environment including conditions of low oxygen and suspension, cells are triggered to become multipotent, and naturally produce proteins associated with skin renewal and scarless healing. The result is a soluble cell conditioned media containing cell-signaling proteins such as KGF, follistatin, stem cell factor, collagens and laminins, which support the epidermal stem cells that renew skin throughout life. In addition, factors associated with scarring, such as TGF-beta, are decreased or nonexistent.

"The applications for this proprietary multipotent CCM within the field of medical aesthetics are numerous and, based upon the way the proteins within the complex signal the body's own stem cells to rejuvenate and regenerate skin, potentially groundbreaking," said Dr. Gail K. Naughton, CEO and Chairman of the Board at Histogen. "This recognition from Suneva's expert team, with a rich background in developing and marketing aesthetics, validates Histogen's technology and supports the fact that it is different from anything currently in the market."

The Alliance for Regenerative Medicine Statement on Use of Cell Therapies Not Approved by the Federal Drug …

By Uncategorized

WASHINGTON, DC--(Marketwire -03/05/12)- The Alliance for Regenerative Medicine issued the following statement today: "An article about stem cell treatments taking place in Texas published by Nature last week is extremely troubling. The article suggests that patients are being administered stem cell treatments that have not been systematically demonstrated to be safe and effective therapies through the established FDA regulatory process.

"Cell therapy treatments, including those using adult stem cells, hold the promise of providing patients with treatments and cures for numerous diseases and disabilities. However, FDA regulation is key to ensuring that the treatments available to patients are safe and effective.

"The Alliance for Regenerative Medicine (ARM), a non-profit organization whose mission is to promote increased funding and development of regenerative medicine products, believes cell therapy and regenerative medicine products, including autologous cell therapy products, must go through the rigorous safety testing that is part of the FDA regulatory process before they can be marketed to the public. These regulations are designed to promote safe collection, manufacture, storage, and use of human cells, and cellular and tissue based products. ARM members comply with these rules because they know that FDA oversight helps to prevent patients from exposure to potentially unsafe products.

"We urge all companies developing stem cell treatments to follow FDA rules governing research and product development. ARM remains committed to working with all stakeholders to ensure that safe and effective products reach patients as soon as possible."

About The Alliance for Regenerative Medicine (ARM) The Alliance for Regenerative Medicine (ARM) is a Washington, DC-based non-profit organization that promotes legislative, regulatory, reimbursement, and financing initiatives necessary to facilitate access to life-giving advances in regenerative medicine. ARM also works to increase public understanding of the field and its potential to transform human healthcare, and provides services to support the growth of its member companies and organizations.

Nuvilex Announces Major Breakthrough in Stem Cell Research

By Stem Cell Treatment

SILVER SPRING, Md.--(BUSINESS WIRE)--

Nuvilex, Inc. (OTCQB:NVLX), an emerging biotechnology provider of cell and gene therapy solutions, released information today about the companys cell encapsulation technology and the breakthrough in stem cell research which overcomes specific fundamental challenges faced in stem cell therapyhost rejection and migration of implanted cells away from the target site.

Stem cell therapy is believed by many medical researchers as holding a key to treating cancer, Type 1 diabetes mellitus, Parkinson's disease, Huntington's disease, Celiac Disease, cardiac failure, muscle damage, neurological disorders, and other chronic, debilitating diseases. There are presently >1,400 registered trials using stem cells that are recruiting patients (ClinicalTrials.gov). The encapsulation technology being advanced allows live stem cells to be implanted into robust, flexible and permeable capsules where they can replicate inside the capsules at the target site free from attack by the bodys immune system and free to undergo natural changes to become the appropriate cell type needed.

The Goldman Small Cap Research report, issued February 29, 2012, noted some inherent difficulties encountered in stem cell treatments, such as keeping stem cells alive for significant periods of time, potential rejection of the cells and subsequent destruction by the recipients immune system, and the migration of the stem cells away from the critical treatment site, while making a distinction that the Companys cell encapsulation technology overcomes these concerns.

The report also accurately recognized, Cells encapsulated in SG Austrias porous beads remain alive for long periods of time in humans, surviving intact for at least two years. Once encapsulated, cells are protected from the bodys immune system. Furthermore, encapsulated cells remain within the beads and do not migrate out of the beads to other sites in the body.

In assessing the overall importance of this technology to Nuvilexs overall business model, Goldman pointed out, The Companys acquisition of the Cell-in-a-Box approach along with the expertise of SG Austria could significantly advance the implementation and utilization of stem cells for a host of debilitating diseases and conditions, in addition to being used to target cancer cells, thus making it a uniquely valuable commodity. We believe that by partnering with leading players in the field, Nuvilex could find that companies with deep pockets would be happy to collaborate or license the delivery system and engage in further research which could result in meaningful development and licensing revenue.

Dr. Robert Ryan, Chief Executive Officer of Nuvilex, added, There is a broad range of expanding research supporting the use of stem cells to treat a variety of human diseases and conditions. Our technology allows for precise maintenance and localization of stem cells, preventing their loss from the critical area of need, that will enable us to potentially create miniature organs at specific sites and as a result we believe greater utilization of those stem cells at the site for their intended purpose, once implanted. As stem cell treatments advance, we expect Nuvilex to be at the forefront of developing new, significant, life changing therapies.

For a detailed review of the research report and valuation methodology, investors are directed to the Goldman Research Report.

About Nuvilex

Nuvilex, Inc. (OTCQB:NVLX) is an emerging international biotechnology provider of clinically useful therapeutic live encapsulated cells and services for encapsulating live cells for the research and medical communities. Through our effort, all aspects of our corporate activities alone, and especially in concert with SG Austria, are rapidly moving toward completion, including closing our agreement. One of our planned offerings will include cancer treatments using the companys industry-leading live-cell encapsulation technology.
