Electron microscopy confirms the presence of melanocytes and mast cells in transgenic mice. (a) TG1 mouse with membrane/soluble epidermal SCF has numerous dermal mast cells (arrowheads) as well as dermal melanocytes (arrows). Asterisks, the boundary of the dermis and hair follicle. Higher magnification images of mast cell and melanocyte are shown in b and c, respectively. Original magnifications: (a) 2,750, (b) 9,000, (c) 11,750.
