Stem cells found in adult skin can be transplanted and function in mouse models of disease

...thing. "Previous work has only dealt with SKPs in culture and their more basic biology. Now we have shown that SKPs can make at least one cell type that functions as predicted in animals," said Dr. Rajiv Midha, study author, a scientist at the Hotchkiss Brain Institute as well as chairman of the Division of...

...re effective anti-HCV therapy. Using the OR6 cell culture assay system, they evaluated the anti-HCV activities of five statins: atorvastatin, fluvastatin, lovastatin, pravastatin and simvastatin. When the statins were tested alone, all except pravastatin inhibited HCV replication. Fluvastatin had the strong...

New technology addresses female fertility preservation

...stern University has developed a three-dimensional culture system that encapsulates follicles and allows immature eggs to grow and mature in vitro. (A follicle is a small spherical group of specialized support cells surrounding each egg.) This novel technology has already led to the live birth of healthy mic...
