Fig. S5: Contact between CTs and cardiomyocytes. The CT cell body does not contact or form a junction with cardiomyocytes. Many microfilaments that are arranged as a vertical and horizontal network with collagen fill the gap to link the CT cell body with cardiomyocytes (A-F). In addition, the cell body of one CT is able to closely connect with the cell body of another CT (D), and the cell body of one CT is able to form a nanometer-range connection with the telopode of another CT (E,F; circle). Distinct from contacts between the far ends of telopodes from different CTs, two telopodes from different CTs are able to form a nanometer-range connection via a gap-juction-like structure (E, F; dotted line circle). Scale bar: Size as shown in the figures. CT: Cardiac telocyte. C: Collagen and extracellular matrix. Mt: Mitochondria. M: Cardiomyocyte. Tp: Telopode. Image published in: Lv L et al.
