Follica Developing Breakthrough Discovery to Treat Hair Loss, Wounds and Other Degenerative Skin Disorders
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.
By studying wound healing on a molecular level, Dr. George Cotsarelis
and colleagues discovered that the skin has the ability to revert to a more
primitive or “embryonic” state as stem cells migrate to the affected area,
thereby achieving a regenerative capacity not previously appreciated to
occur in adults.
The researchers were able to control the regenerative response,
including the extent of new hair follicle formation, by manipulating
genetic pathways during this “embryonic window” when new follicles formed.
The new hair follicles functioned normally, cycled through the normal
stages of hair growth and exhibited normal architecture, including a full
complement of stem cells. Cotsarelis and colleagues showed that the
induction of this primitive state triggered corresponding embryonic
molecular pathways distinct from those active in corresponding cells in
adult skin, opening up new treatment options not previously thought to have
therapeutic benefit in normal adult skin.
“The ‘embryonic window’ gives us the opportunity to develop disease
treatments that act in entirely novel ways,” said Daphne Zohar, PureTech
Ventures founding managing partner and Follica CEO. “The clinical
translation of this technique involves straightforward, safe dermatological
procedures, and we are studying the impact of multiple drugs and drug-like
compounds on this regenerative response as we advance in preclinical
“This is an extremely exciting discovery and shows promise for
treatment of follicular disorders such as hair loss and unwanted excess
hair,” noted Dr. Vera Price, co-founder of the National Alopecia Areata
Foundation, director of the University of California, San Francisco (UCSF)
Hair Research Center and a founding scientific advisory board member of
“The hair follicle is an elegant structure that plays many different
roles for human skin, aside from growing hair,” said Dr. Rox Anderson,
Professor of Dermatology at Harvard Medical School, Director of the Wellman
Center for Photomedicine at Massachusetts General Hospital, and founding
chairman of Follica’s scientific advisory board. "George Cotsarelis’
insights into the biology of hair follicles provide new strategies for
preventing and treating a variety of skin and hair disorders."
