Caption Electron micrographs of yolk sac visceral endodermal cells from wild-type and Apobtm3Sgy/Apobtm3Sgy mice. Embryos were dissected in saline. Portions of the yolk sac membranes were removed for genotype analysis of Southern blotting, and the remainder were transferred to a fixation buffer. Sections were stained for lipids using imidazole-buffered osmium tetroxide. Sections from wild-type (A), Apobtm3Sgy/Apob+ (+/-, B), and Apobtm3Sgy/Apobtm3Sgy (-/-, C) yolk sacs are shown. Intracellular cytosolic lipid droplets (LD) located at the basal aspect of the visceral endodermal cells are rarely observed in wild-type cells but are evident in increasing amounts in heterozygous and homozygous mutant cells. Arrows point to Golgi apparatus regions, which stain for lipids intensely in wild-type cells, much less intensely in heterozygous cells, and not at all in homozygous cells. Magnification, 5,600x.
