Figure 4.

Vesicles and caveolae of CTs. Many vesicles (arrowhead) or coated vesicles (white arrowhead) are present in the telopodes. In addition, many caveolae are present in the membrane of the cell body and telopode (small triangle). The opening site of caveolae faces the extracellular space, and some vesicles or coated vesicles are located near the opening site of caveolae (A‐C). C: Collagen and extracellular matrix; CT: Cardiac telocyte; M: Cardiomyocyte; Mt: Mitochondria; N: Nucleus. Scale bar: Size as shown in the figures; Tp: Telopode
