BOSTON, June 3, 2013 /PRNewswire/ -- Technology exclusively licensed by Follica Inc. from the Perelman School of Medicine at the University of Pennsylvania has been used to demonstrate a new approach to regenerate hair follicles in adult mammals which could be used therapeutically in humans. The paper describing the data was published advanced online in Nature Medicine. The paper's principal investigator, George Cotsarelis, MD, chair of Dermatology in the Perelman School of Medicine...

Male baldness, long considered the bane of men all over the world, may become a thing of the past after researchers found a biological clue that could raise the prospect of stopping and perhaps even reversing hair loss. The researchers, from University of Pennsylvania's Perelman School of Medicine, have identified an abnormal amount of protein called Prostaglandin D2 (PGD2) in the bald scalp of men with male pattern baldness. Lab studies were conducted using mice and cultured human hair...

New research suggests that male-pattern baldness may result from stem cells in the scalp failing to give rise to progenitor cells, which are the cells responsible for growing hair. Researchers write in the Journal of Clinical Investigation that stem cells could be a potential treatment to grow new hair. "Even in a bald scalp, there are stem cells there that you could activate to get new hair," said Dr. George Cotsarelis, chair of the Department of Dermatology at the University of...

Given the amount of angst over male pattern balding, surprisingly little is known about its cause at the cellular level. In a new study, published in the Journal of Clinical Investigation, a team led by George Cotsarelis, MD, chair of the Department of Dermatology at the University of Pennsylvania School of Medicine, has found that stem cells play an unexpected role in explaining what happens in bald scalp.Using cell samples from men undergoing hair transplants, the team compared follicles...

BOSTON, May 16 /PRNewswire/ -- Technology licensed by Follica Inc. from the University of Pennsylvania School of Medicine has been used to generate completely new hair follicles for the first time in normal adult mammals. The paper describing the experiment was published in the May 17th issue of the scientific journal Nature.
