A-I. Correlative light electron microscopy (CLEM) showing Prom1 at the plasma membrane of primary hepatocytes. Primary hepatocytes were isolated from 12-week-old male WT (Prom1+/+) or KO ( Prom1cre-ert2-nlacz) mice. The boxed areas in panel (A, D, G) and (B, E, H) were magnified and presented as panel (B, E, H) and (C, F, I), respectively. Scale bar; 5 μm (A, D and G), 1 μm (B, E and H), and 0.2 μm (C, F and I).
