Skin histologic changes during gestation. In whole mount, the skin of 17 dpc CD-1 fetuses appeared more translucent (A) than that of 19 dpc fetuses (C). H&E-stained sections of dorsal skin from 17 dpc fetuses had thinner epidermal (E) and dermal papillary (DP) layers and contained fewer hair follicles (asterisks) than H&E-stained sections of skin from 19 dpc fetuses (B and D).
