A stem cell capable of regenerating both bone and cartilage has been identified in bone marrow of mice. The discovery by researchers at Columbia University Medical Center (CUMC) is reported today in the online issue of the journal Cell.

Tracing Cancer Back to Its Origins

Some bladder cancers look like tiny fingers. Others look like flat bed sheets.

The differences are obvious and they have clinical implications. The “fingers” of papillary tumors often grow back after surgery, but flat carcinoma in situ cancers are typically more aggressive and more likely to spread.

“The big question is why,” says Cathy Mendelsohn, PhD, a professor of urology, pathology & cell biology, and genetics & development, who has been studying bladder development and regeneration at Columbia. “Because if we understand how cancers arise, and why some lesions invade and others don’t, we may be able to develop more precise techniques for diagnosis and better therapies for treatment.”
