Inadditional studies, the researchers found that regressing BCC cellscould be reprogrammed to differentiate into various epithelial celltypes, ultimately capable of assembling fully-formed hair follicles.These results suggest that BCCs contain cells capable of multi-lineagedifferentiatio...

Weill Cornell Research Reveals Secrets Of Trafficking Within Cells

...It's an incredibly important life process, and now researchers at Weill Medical College of Cornell University in New York City have used an exciting new technology to better understand how one key player -- a protein called clathrin -- helps regulate endocytosis like a well-oiled machine. It may also give us ins...
