are difficult to obtain and complicated to prepare and coordinate. This new cooperation will allow many more of our patients, suffering with complex joint injury, to be treated in a timely and effective manner," Crawford said. Crawford who perfor...
Researchers first to map gene that regulates adult stem cell growth
... in blood marrow transplants. Currently, stem cell transplants
with cord blood can only be used in children because cord blood does not contain enough stem cells for an amount needed to be transplanted into an adult. The only stem cell population that has been examined for effects of Latexin to date is in bone...
Stem cell transplants explored at Stanford as a possible treatment for hearing loss
...two different approaches - new drugs and stem cell transplants
- are important because drug treatments are unlikely to help everyone. For some people with genetically caused hearing disorders, he explained, no drug is likely to help. "For them, stem cell transplantation may be the answer," he said But for...
