Fig. 2From: Injury induced expression of caveolar proteins in human kidney tubules - role of megakaryoblastic leukemia 1Parietal epithelial cells of Bowman’s capsule display a high density of caveolae as demonstrated by electron microscopy. Panels a and b show presence of caveolar invaginations in apical and basal plasma membranes of PECs, marked by arrowheads (insets show higher magnification views). Scale bar: 0,5 μm. Panel c shows the size distribution of caveolae in PECs as compared to human detrusor smooth muscle cells, showing a median size of 80 nmBack to article page
