Human Embryo Skin (8-9 week EGA)

TEM of embryonic epidermis showing periderm and basal layer.

Desmosomes are circled and enlarged in k, and the area of the basal cell enlarged in i is enclosed within the box. Note that cells of both layers are filled primarily with glycogen. (I) TEM of a periderm cell showing fine bundles of keratin filaments (arrows).
