Donor MSCs release apoptotic bodies to improve myocardial infarction via autophagy regulation in recipient cells.

abstract：:In macroautophagy (hereafter autophagy), a morphological hallmark is the formation of double-membrane vesicles called autophagosomes that sequester and deliver cytoplasmic components to the lysosome/vacuole for degradation. This process begins with an initial sequestering compartment, the phagophore, which expands int...
