Characteristics of the isthmus and infundibulum, and hair bulb of nude-mouse pelage follicles after transplantation of the upper part of whisker follicles from ND-GFP mice. (a) Longitudinal section of a nude-mice pelage follicle from isthmus to infundibulum in the mice transplanted with upper part of whisker follicles from ND-GFP mice or non-transplanted control mice. Scale bar = 50 µm. (b) Transverse section of a nude-mice pelage follicle at the isthmus in the transplanted mice or non-transplanted control mice. Scale bar = 25 µm. (c) Longitudinal section of a nude-mice pelage follicle at the hair bulb in the transplanted mice or non-transplanted control mice. Scale bar = 50 µm. (d) Transverse section of nude-mice pelage follicle at the hair bulb in the transplanted mice or non-transplanted control mice. Scale bar = 25 µm. White dotted lines outline the pelage follicle. White arrowheads indicate the HAP stem cells which jumped to the pelage follicle.
