Abstract
The a thickening of the basal aspect of the epidermal melanocyte was studied with the electron microscope. A 250–330 A cytoplasmic electron zone abuts on the internal leaflet of that portion of the trilaminar melanocyte plasma membrane that is apposed to the basal lamina; this electron zone is not seen where the melanocyte plasma membrane is apposed to that of a keratinocyte. Melanocyte cytoplasmic filaments do not appear to converge on this zone. 50–70 A anchoring filaments apparently arising from the basal lamina appear to insert into the external leaflet of that portion of the melanocyte plasma membrane subjacent to the cytoplasmic electron zone. The similarities to and differences from basal cell hemidesmosomes are enumerated. This structure probably represents a melanocyte-basal lamina attachment device. It is suggested that Odland's (5) original designation, dense plate, be retained.
