Allele Biotechnology Initiates Project On Scaled Manufacturing Of Induced Pluripotent Stem Cells And Differentiation With Chinese Academics

Allele Biotechnology has signed an agreement with Jinan University to develop culturing systems of stem cells and differentiation methods for producing skin tissue cells for wound treatment and stem cell therapy.

San Diego, California (I-Newswire) January 16, 2013 – Allele Biotechnology and Pharmaceuticals, Inc., a San Diego based company with a focus on new technology development, announced today that it has signed an agreement with the Biomedical Institute of Jinan University through a focus group to develop culturing systems of stem cells and differentiation methods for producing skin tissue cells for wound treatment. The joint team will also evaluate using stem cell therapy as potential treatment for arthritis, Lupus, and other autoimmune-related diseases.

Scientists from Allele Biotechnology recently described an important advance in the generation of stem cells capable of producing all the different tissues of the human body. Using messenger RNA molecules and without the need of viral vectors, animal products or feeder cells, this new method can be used to reprogram human fibroblasts into induced pluripotent stem cells (iPSCs). The efficiency is significantly improved over previously reported reprogramming results and the time required to complete reprogramming is slashed in half under optimal conditions.

The Biomedical Institute at Jinan University, a leading comprehensive research university in South China, has focused on translational research in the areas of epidemic diseases and autoimmune diseases. It has broad collaboration with partners and close connections to the biotech industry in China. It was known to have launched (licensed) a number of new biologics in China, and contributed to the understanding and diagnostics of the SARS epidemic in 2003. The institute has also been entitled as the national engineering research center of biopharmaceutics since 2005.

This collaboration will last for at least 2 years, and will go beyond the R&D stage with selected candidates moving into clinical trials, first in China, then in other countries. If the project reaches clinical trials it will be funded jointly by industry and academic partners in the range of $10 million USD.

American CryoStem Corporation (OTCQB:CRYO), announced the launch of its newest adult stem cell and adipose tissue collection center in Bellevue, Washington

A public company doing business of preparing and providing adipose (fat) tissue and adipose derived adult stem cells, American CryoStem Corporation (OTCQB:CRYO), announced the launch of its newest adult stem cell and adipose tissue collection center in Bellevue, Washington. Dr. Fredric Stern will officially launch the new Stern Center Stem Cell Collection Service as the first to provide Adult Stem Cell and Tissue Banking services to the general public in the Seattle, Washington area.

“Having successfully worked with American CryoStem in the past we are truly excited about the official launch of these adipose tissue based services to the general public in Washington. I look forward to working with American CryoStem on educating my patients about the Regenerative Medicine benefits of “bio-banking” and the latest fat transfer cosmetic services now available at the center. I chose to affiliate my practice with American Cryostem because of their thorough scientific approach to stem cell banking and strict adherence to aseptic technique and FDA guidelines,” said Dr. Fredric Stern, the founder of The Stern Center and a plastic surgeon.

John S. Arnone, CEO said, according to a company news release, “We are excited to have a surgeon with Dr. Stern’s abilities and reputation associated with American CryoStem in the Seattle, WA area and look forward to a productive relationship with the entire Stern Center team. We remain committed to our “Gold Standard” clinical laboratory processing and storage reputation and strive to provide the best physician and patient services in the U.S. The newest stem cell collection center in our network represents our commitment to associate with leading physicians in the Regenerative Medicine Industry.”

Mesenchymal stem cells (MSCs) are typically the products of adipose tissue-isolated stem cells for regenerative medicine or, in this case cosmetic surgeries. The mesenchymal stem cells can also be isolated from bone marrow or embryos. They secret hormones once introduced into human bodies and help balance cytokines in the blood. It is reported that MSCs help reduce several disease symptoms and, in some countries, are used as “youth fountains” in anti-aging treatment. MSCs can be produced fairly easily, in our hands at least, from induced pluripotent stem cells (iPSCs). iPSCs, like embryonic stem cells, can be expanded indefinitely, differentiated into MSCs and all other cell types, and are being tested in various cell therapies including those that are mediated through the MSC stage.

NIDA Branch Chief, Jonathan D. Pollock, Ph.D., Encourages SBIR/STTR Grants on Reagent Kits Including iPSC

“We’re interested in areas of genetics, in terms of smoking cessation, pharmacogenomics, treatment of substance abuse, and particularly right now, issues related to prescription substance abuse,” Jonathan D. Pollock, Ph.D., chief of the Genetics and Molecular Neurobiology Research Branch at NIDA’s Division of Basic Neuroscience and Behavioral Research, told GEN.

In addition to that solicitation, Dr. Pollock said, the branch is interested in supporting commercialization and development of products, resources, and services through SBIR/STTR relevant to brain research. They include protein capture reagents, proteomics, genomics, pharmacogenomics, molecular diagnostics, nanotechnology, gene delivery and viral vectors, identification of RNA and DNA sequences in formalin fixed nervous tissue, shRNA, microfluidics, epigenetics diagnostics, therapeutics, and tools to detect epigenetic modifications.

The branch is also looking to support commercialization and development of biomarkers, optogenetics, reagents for iPS and neural stem cells, technologies to uniquely barcode cell types, improved super resolution microscopy methods, in vivo gene expression imaging, automated sectioning, image acquisition and 3D reconstruction of electron micrographic sections, genetically encoded markers for electron microscopy, and “big” genomic and proteomic data, including data visualization, data contextualization, and data analysis.

“What we’re really looking for is products that you could basically commercialize coming out of research. These can be things that are either products or services. I think that there are opportunities, particularly for groups of individuals that have an idea, IP, and want to have a startup company.”

SBIR/STTR grants account for 2.8% of NIDA’s roughly $1 billion annual budget. NIDA spent $26.679 million on SBIR and STTR in fiscal year 2012, which ended September 30—up from $26.497 million in FY 2011. The number of SBIR/STTR research projects grants rose to 56 in FY 2012 from 44 a year earlier, according to the GEN article.

Allele Biotech’s CEO, Jiwu Wang, Ph.D., has worked with Dr. Pollock on a previous, VHH nanobody-related project under the NIDA SBIR program. He has just submitted a SBIR grant application based on Allele’s recently published mRNA-based reprogramming technology, after discussion with Dr. Pollock.

The 2012 Nobel Prize for Physiology or Medicine is Awarded to Cell Reprogramming Scientists

Monday Sir John B. Gurdon and Shinya Yamanaka shared this year’s Nobel Prize for physiology or medicine for work that revolutionized the understanding of how cells and organisms develop.

“By reprogramming human cells, scientists have created new opportunities to study diseases and develop methods for diagnosis and therapy.”

This is the 3rd time that a Nobel Prize is awarded on a technology that we chose as our area of research and made contributions to the field. The other two are RNA interference (2005) and fluorescent proteins (2008).

Path to Better Drugs through Disease-Specific iPSCs

Induced human pluripotent stem cells

The recent finding that pluripotency, the ability to differentiate into all cell types typically associated with embryonic stem cells, can be induced in somatic cells may be the molecular equivalent of the discovery of antibiotics or vaccines in the last century [1].

iPSC-based disease modeling

Recent studies have described the generation of induced pluripotent stem cells (iPSCs) from patients with a full range of genetically inherited or sporadic diseases, and in vitro differentiation of these iPSCs to cell types relevant to the disorder with certain disease features.

Example 1 (out of ~20): Progressive motor neuron loss during differentiation of iPSCs derived from spinal muscular atrophy (SMA) patients, reflecting developmental loss seen in the disease.
Example 2: iPSCs made from RETT syndrome give rise to glutamatergic neurons with fewer synapses than controls, a better treatment was found from a panel of candidates based on this model.
Example 3: Neurons differentiated from iPSCs that have been derived from early or late onset Alzheimer’s disease were shown to display different properties and potential interference points.
The identification of novel pathways or drugs that could prevent disease is the ultimate goal of the iPSC-based disease modeling approach.

Major steps towards efficient iPSC disease modeling

The first hurdle for feasible application of patient-specific disease modeling is to achieve efficient generation of iPSCs from large cohorts of patients quickly and at a low cost while eliminating “clonal variations”. As described in a recent publication [2], the Allele Biotechnology team has shown that human fibroblasts can be converted to stem cells in just over a week, achieving bulk conversion efficiency without any chromosome modifications. The process is also xeno-free and feeder-free, enabling both fundamental scientific research and clinical applications.

The next major advancements required for disease modeling are robust lineage-specific differentiation protocols that provide a large number of desired cells for drug testing and screening. Cardiomyocytes derived from iPSCs have been the best known example of large expansion; other cell types will become available in the near future. Allele Biotechnology has commenced differentiating iPSCs along several lineages using our own iPSCs of superior quality.

With cells of disease-matching tissue types derived from patients’ iPSCs, cell-based assays can be designed and developed using various assay formats. Allele Biotech’s leading capacities in fluorescence and bioluminescence, gene silencing, delivery vehicles and single-domain targeting agents will be of unmatched value to drug discovery partners.
