endocrine/exocrine glands
• at P15 and P18

integument
• at P15 and P18
• at P12, mice exhibit defects in the hair shaft
• beginning at P5, mice exhibit abnormal hair follicles
• hair follicles undergo epidermalization unlike in wild-type mice
• at P12, mice exhibit defects in the inner root sheath with continued proliferation of outer root sheath cells in catagen and telogen unlike in wild-type mice
• at P9, follicles have not develop hair bulbs and exhibit abnormal undifferentiated shafts with no keratinized medulla unlike in wild-type mice
• at P18, mice fail to exhibit upward movement of the hair shaft and formation of the club structure in the upper hair bulb as in wild-type mice
• by telogen phase P20, hair follicles undergo regression and fail to re-initiate the hair cycle as in wild type mice
• at P15, P18 and P26, proliferation of hair follicle cells is increased compared to in wild-type mice
• the dermis is thickened and hypercellular compared to in wild-type mice
• at P15 and P18, utricles develop in the epidermis unlike in wild-type mice
