Transmission electron microscopy. (a) Electron microphotograph of a newly formed capillary tube from the mouse aortic explant in the collagen gel. A cross-section shows a capillary tube with a lumen that contains cell debris. Pericyte-like cells () surround the tube. The edges of the cells are in contact with each other. Scale bar = 2 μm. (b) Electron microphotograph of a longitudinal section of a capillary tube. Pericyte-like cells () surround the tube. Scale bar = 2 μm.
