IntelliCell BioSciences filed its patent application with the US Patent office that will claim priority to its provisional US patent serial #61/427, 221 that was filed on December 27, 2010. The title of the patent application is Ultrasonic Cavitation Derived Stromal or Mesenchymal Vascular Extracts and Cells Derived Therefrom Obtained from Adipose Tissue and use Thereof. It covers the methods of manufacturing using ultrasonic cavitation to dissociate the fat cells and blood vessels contained within the adipose tissue, thereby obtaining multi-potent, mesenchymal or stromal vascular fractions for use in human subjects. These methods do not include the use of any exogenous dissociating enzymes such as collagenase and result in increased number of cells which constitute the multi-potent, mesenchymal or stromal vascular fractions (about ten folds greater than methods which use collagenase to isolate these cells).

Dr. Steven Victor, the inventor, and CEO of IntelliCell BioSciences commented “we are extremely excited to have filed this patent in the US and around the world. The use of ultrasonic cavitation allows physicians to use less than 60cc’s of adipose tissue (fat) to manufacture approximately a half billion to 1.4 billion stromal vascular fraction cells (SVF cells) within five to ten minutes. The use of sound and water allows this manufacturing method to be utilized by physicians in the US underneath FDA (PHS Act Section 361 1271.10 (a)) of the health bill passed by Congress in 2009.

This manufacturing method has significant cost and time advantages over any other method of producing SVF cells. These cells have been used around the world for conditions caused by inflammation, such as lower back pain, migraines, MS, autism, fibromyalgia, tinnitus, arthritis; tissue repair, such as growing cartilage for bone on bone knee repair; bone and gingival tissue (gum disease): cosmetic indications such as fat grafting, wrinkle removal and other cosmetic procedures. The success rate for these patients has been approximately 80% plus. We believe that the use of non-enzymatic SVF cell therapy will find its first applications in treating sports related injuries. We are proud to have numerous luminaries on our advisory board who are leaders in the sports medicine world. We anticipate significant revenues from the utilization of SVF cells from the various IntelliCell BioSciences Centers of Excellence in the year 2012.

An Iranian scientist managed to develop a new method to propagate human spermatogonial stem cells from small testicular biopsies to obtain adequate number of cells for successful transplantation for 18000-fold in vitro, leading to protection of the fertility of immature boys suffering from cancer.

The research carried out jointly with Amsterdam University in Holland is the first developed method in the world.

Hooman Sadri-Ardekani, Ph.D in Reproductive Medicine and a Professor in Avicenna Institute-ACECR told ISNA, “Young boys treated with high-dose chemotherapy are often confronted with infertility once they reach adulthood and cryopreserving testicular tissue before chemotherapy and auto transplantation of spermatogonial stem cells at a later stage could theoretically allow for restoration of fertility.”

A new cornea may be the only way to prevent a patient going blind – but there is a shortage of donated corneas and the queue for transplantation is long. Scientists at the Sahlgrenska Academy have for the first time successfully cultivated stem cells on human corneas, which may in the long term remove the need for donators.

Approximately 500 corneal transplantations are carried out each year in Sweden, and about 100,000 in the world. The damaged and cloudy cornea that is turning the patient blind is replaced with a healthy, transparent one. But the procedure requires a donated cornea, and there is a severe shortage of donated material. This is particularly the case throughout the world, where religious or political views often hinder the use of donated material.

As former House speaker Newt Gingrich courts evangelical voters in advance of Tuesday’s Florida primary, he is drawing an increasingly hard line against the use of embryonic stem-cell research — a position that contrasts not only with that of former Massachusetts governor Mitt Romney, but also with statements that Gingrich himself has made on the subject in the past.

Speaking at a Baptist church in Winter Park on Saturday, the former speaker received a standing ovation when he declared that embryonic stem-cell research amounts to “the use of science to desensitize society over the killing of babies.”

And in a news conference Sunday, he said he would ban all embryonic stem-cell research, including that done on discarded embryos created by in vitro fertilization.

Mouse skin cells can be converted directly into cells that become the three main parts of the nervous system, according to researchers at the Stanford University School of Medicine. The finding is an extension of a previous study by the same group showing that mouse and human skin cells can be directly converted into functional neurons.

The multiple successes of the direct conversion method could refute the idea that pluripotency (a term that describes the ability of stem cells to become nearly any cell in the body) is necessary for a cell to transform from one cell type to another. Together, the results raise the possibility that embryonic stem cell research and another technique called “induced pluripotency” could be supplanted by a more direct way of generating specific types of cells for therapy or research.

This new study, published online Jan. 30 in the Proceedings of the National Academy of Sciences, is a substantial advance over the previous paper in that it transforms the skin cells into neural precursor cells, as opposed to neurons. While neural precursor cells can differentiate into neurons, they can also become the two other main cell types in the nervous system: astrocytes and oligodendrocytes. In addition to their greater versatility, the newly derived neural precursor cells offer another advantage over neurons because they can be cultivated to large numbers in the laboratory — a feature critical for their long-term usefulness in transplantation or drug screening.

In the study, the switch from skin to neural precursor cells occurred with high efficiency over a period of about three weeks after the addition of just three transcription factors. (In the previous study, a different combination of three transcription factors was used to generate mature neurons.) The finding implies that it may one day be possible to generate a variety of neural-system cells for transplantation that would perfectly match a human patient.

Vet-Stem Inc. announced that over 8000 animals have now been treated with Vet-Stem cell therapy.

Vet-Stem began providing stem cells to veterinarians in 2004 and has now provided stem cells for the treatment of over 8,000 animals. Vet-Stem was the first company to introduce rapid turnaround stem cell services in the US.

After providing stem cells for thousands of horses, Vet-Stem pioneered stem cell therapy in dogs and cats and is now the world leader in Regenerative Veterinary Medicine. The rapid adoption of stem cell therapy by equine veterinarians and horse owners provided a springboard for use in small animal veterinary medicine.

Greater than 75% of horses treated with Vet-Stem cell therapy for tendon and ligament injuries are able to return to their previous level of performance. Dog owners report that greater than 80% of dogs treated with Vet-Stem cell therapy have an improved quality of life.
