Autocrine role of senescent cardiac fibroblasts-derived extracellular vesicles.

ABSTRACT: Cellular senescence is a highly stable state associated with cell cycle arrest, that is elicited in response to various stresses. The accumulation of senescent cells in tissues drives age-related diseases. Recent studies have shown that the cellular senescence enhances an extracellular vesicles (EV) secretion. EV are lipid-bilayer-capsuled particles released by various cells mediating cell-to-cell communication. It was recently reported that EV secreted by the senescent cells had several functions such as cancer cell proliferation and immune cell activation. In the present study, we investigated whether senescent cardiac fibroblasts-derived EV play an autocrine/paracrine role in the heart cells. Neonatal rat cardiac fibroblasts (NRCFs) were treated with doxorubicin (DOX) to induce cellular
