Snippet from the article/interview:
For over a decade, leading hair biology scientists. Dr. Rolf Hoffmann and Dr. Kevin McElwee, have been studying the potential of dermal sheath cup cells to spark hair regeneration and the rejuvenation of miniaturized hair follicles. Hoffmann, RepliCel’s Chief Medical Officer, discusses his research, the process of developing this treatment, and the critical steps the company is taking along the way to ensure that it is successful.
Interesting reading! What little I know of RepliCel has been written before here, but this interview explains about their study of the dermal sheath cup cells and how this differs from others doing similar research.
