Study identifies 5 genetic themes key to keeping stem cells in a primitive, flexible state

...ain their identity is key to the emerging field of regenerative medicine. “These findings may help us to understand how the key genes which control cell fate are regulated, and how, when dysregulated, they can lead to disease. This may ultimately allow us to develop targeted therapies to stimulate adult stem cell...

Adult stem cells from human cord umbilical cord blood successfully engineered to make insulin

...embryonic stem cells, doctors practicing so-called regenerative medicine eventually might be able to extract stem cells from an individual’s blood, then grow them in the laboratory to large numbers and tweak them so that they are directed to create a needed organ. In this way, he said, physicians might avoid the ...

First demonstration of new hair follicle generation in an animal model

...rally believe that mammals had essentially no true regenerative qualities. (The liver can regenerate large portions, but it is not de novo regeneration; some of the original liver has to remain so that it can regenerate.) In this study, researchers found that wound healing in a mouse model created an “embryoni...

The sturdier sex? -- Study by Pittsburgh scientists finds female stem cells work better

...ology, is the first ever to report a difference in regenerative capabilities of muscle stem cells based on sex. ...sed on these results, future studies investigating regenerative medicine should consider the sex of the stem cells to be an important factor. Furthermore, investiga...

Cloned mice created from fully differentiated cells, a milestone in cloning research

...urrent studies may have important implications for regenerative medicine, since the findings suggest the potential of adult stem cells in this arena may be more limited than previously thought. However, of particular interest to Dr. Cheng is the relevance of their findings to cancer stem cell research. "An inte...

Stem cells engage in dialogue with the cells that regulate their futures

...hola-Baker added that stem cells hold high hope in regenerative medicine: tapping into the ways cells repair the body to create therapies to fix or replace injured tissues. She mentioned that it is thought that most, if not all, adult tissues contain stem cells. Through self-renewing division," she explained, ...

Diabetes slows nerve recovery after heart transplant

...lanted heart as a very specific model to study the regenerative capacity of the heart's sympathetic nervous system, we determined that reinnervation--or the heart's ability to develop new nerves to replace damaged ones--is slower in diabetic patients," said Frank M. Bengel, a visiting associate professor of radio...
