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
Warnings are being issued by experts of the dangers of medical tourism saying that unproven stem cell therapy overseas could leave patients worse off.
Signing up for stem cell therapy is worth the risk for many people who are suffering with conditions like spinal injury, multiple sclerosis, motor neuron or Parkinson’s disease.
A medical journal reported earlier this year that an Israeli teenager developed brain tumors after experimental injections at a Russian clinic.
There are alternate reports also of patients contracting meningitis after treatments in China.
A handbook will be released by the Australian Stem Cell Centre to help patients analyze radial stem

First and foremost, the new international guidelines on stem cells, with four Italians among the authors, need to be clear, eliminating false illusions, incredible exaggerations, and confusion due to excess emphasis placed on the therapeutic properties of adult stem cells compared to embryonic stem cells.
The International Society for Stem Cell Research (ISSCR) has decided to impart some order in a field of research which, for various reasons, is growingly involved in issues that have little to do with research.
“Regulation is necessary,” according to the Society, commenting about studies that risk creating exaggerated controversy or omitting risks regarding
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

A study published this week reinforces the potential value of stem cells in repairing major injuries involving the loss of bone structure.
The study shows that delivering stem cells on a polymer scaffold to treat large areas of missing bone leads to improved bone formation and better mechanical properties compared to treatment with the scaffold alone. This type of therapeutic treatment could be a potential alternative to bone grafting operations.
“Massive bone injuries are among the most challenging problems that orthopedic surgeons face, and they are commonly seen as a result of accidents as well as in soldiers returning
