we have studied in regenerating endothelium of rat thoracic aortas ( a ) organization of tight and gap junctions by means of morphometry using freeze-fracture electron microscopy , ( b ) development of cytoplasmic actin microfilament bundles ( stress fibers ) by means of morphometry using thin section electron microscopy , and ( c ) distribution of filipin-sterol complexes in the endothelial plasma membrane using thin section and freeze-fracture electron microscopy .
