Hair follicle neogenesis induced by cultured human scalp dermal papilla cells.
Qiao J,-et al
AIM: To develop a method by which human hair follicle dermal papilla cells can be expanded in vitro while preserving their hair-regrowth potential for use in follicular cell implantation, a cellular therapy for the treatment of hair loss. ...snip..
RESULTS: ....( Hair follicle ) cultures from numerous donors reproducibly resulted in an expansion that averaged approximately five population doublings per passage. Furthermore, the cells consistently induced hair formation in an in vivo graft assay. Grafted DP cells appeared in DP structures of newly formed hairs, as well as in the dermal sheath and in the dermis surrounding follicles. Induced hair follicles persisted and regrew after being plucked 11 months after grafting. A process for the propagation of human DP cells has been developed that provides significant expansion of cells and maintenance of their hair-regrowth inductive capability, overcoming a major technical obstacle in the development of follicular cell implantation as a treatment for hair loss.
