| Research Abstract |
This research project demonstrated that canine hair follicle stem cells are located in a bulge area of hair follicles and high proliferation potency in the hair follicle stem cells. Stem cell marker proteins, K15, follistatin were stained intensely in the bulge area and related genes such as SOX9, LHX2, TCF4 and NFATC1 were expressed in hair follicle cells of bulge area. In vivo transplant of canine hair follicle stem cells with dermal papilla cells to nude mice successfully reconstituted the hair follicle and its adnexa in nude mouse skin. These results may give a new insight not only to canine hair follicle biology but also to human medicine.
