Ultrastructural Evidence of Exosome Secretion by Progenitor Cells in Adult Mouse Myocardium and Adult Human Cardiospheres
Figure 4
Transmission electron micrographs showing exosomes (≈75 nm diameter; Exo. (a)) and microvesicles (≈200 nm diameter; (b)) secreted by cardiac progenitor cells (CPC) in a human CS in vitro. Exosomes in adult mouse myocardium ((c)-(d); TC: telocyte; ESC: extracellular space).
