About the Lab:

The Cotsarelis laboratory works on the role of hair follicle stem cells in hair growth, alopecia, wound healing and skin regeneration. Dr. Cotsarelis first localized hair follicle stem cells to the bulge region of the hair follicle and has developed multiple tools for studying these cells. He is a world-renowned expert on both clinical and basic science aspects of hair physiology and pathophysiology. As such he is an excellent role model of a physician scientist for our trainees. Research in the Cotsarelis lab is well funded by NIH and other granting agencies.

Training Information:

Trainees participate in all areas of research, gaining expertise in stem cell and regenerative biology and specific practical training in areas including molecular biology, generation and analysis of genetic mouse models, FACS analysis, and xenografting. Current and previous trainees are highly productive, and several previous trainees are now tenure-track PI’s at a range of institutions.
