Figure 7.

Electron micrograph of a maturing GB. GB appears as a nodular structure with a centrally placed lipid-containing cell (lip) and comprised of several different cell types: E, endothelial cells; P, pericytes; lip, lipid-containing cell with a cytoplasmic lipid body, LB; MO, monocyte; F, fibroblasts. Cells were identified by examination of this same field at higher magnification, using standard electron microscopic criteria. 59,60 Multiple small vascular lumens (L), many but not all containing red blood cells, are lined by endothelial cells; lesser numbers of pericytes are scattered in between. Scale bar, 10 μm.
