Embryonic stem cells, reprogrammed skin cells have inherent differences

Kathrin Plath

UCLA researchers have found that embryonic stem cells and skin cells reprogrammed into embryonic-like cells have inherent molecular differences, demonstrating for the first time that the two cell types are clearly distinguishable from one another.

The data from the study suggest that embryonic stem cells and the reprogrammed cells, known as induced pluripotent stem (iPS) cells, have overlapping but still distinct gene expression signatures. The differing signatures were evident regardless of where the cell lines were generated, the methods by which they were derived or the species from which they were isolated, said William Lowry, a researcher with

Milestone of 8000 animals treated with Vet-Stem cell therapy

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

Indian doctors cure thalassaemia using stem cells

When others of her age played with dolls, eight-year-old Thamirabharani was taking blood transfusions.
Born with thalassaemia, she has, however, found hope. She was detected with the disease when she was a year and a half and has been undergoing regular blood transfusions since.

Haematologist Revathy Raj and his team from Apollo Gleneagles hospital in Chennai gave a new lease of life to the little girl from Coimbatore through stem cell transplantation. Doctors said she is now fully cured and has not needed a single transfusion since March.

Doctors claimed this is the first success story in India using the stem cells

Hysterectomies a stem cell source

Discarded fallopian tubes from hysterectomies could be a good source of donor stem cells, say researchers.
Work shows they are an abundant source of the immature cells that have the potential to become a variety of the body’s tissues, like muscle and bone.

The discovery offers another “ethical” route to creating stem cell treatments for diseases like arthritis without using embryos.
The findings are published in The Journal of Translational Medicine.
Experts have already shown that getting mesenchymal stem cells from umbilical cords, menstrual blood, teeth and fat tissue is viable.

Discarded tissue

The latest work by a Brazilian team from the University of São

ITALY – New Method Found to Program Adult Stem Cells

A new method to reprogram adult cells making them similar to stem cells has been discovered. The key protein in the discovery is Wnt, already known to scientists for its involvement in numerous phases of development in vertebrates and invertebrates. The study, conducted by the Telethon Institute of Genetics and Medicine (TIGEM) in Naples by Maria Pia Cosma, was published in the online version of Cell Stem Cell magazine. The study involved various types of adult cells including fibroblasts, thymus cells, and neural precursor cells, which were fused with embryonic stem cells in the presence of the
