A notable population of extracellular vesicles (EVs) is generated during apoptosis, known as apoptotic vesicles (apoVs). These apoVs are increasingly the subject of studies concerning their identity and mechanisms of production, which have been revealed unique biological and functional characteristics that are emerging as crucial regulators for diverse processes. Furthermore, apoVs have been gradually noticed for their essential role in regulating the physiology of various organ systems <i>in vivo</i>, and growing evidence suggests that apoV dysregulation contributes to age- and pathology-associated tissue alterations. Importantly, apoVs can be therapeutically harnessed to unleash their potential in treating several diseases such as immune disorders, osteoporosis, cutaneous wound and acute liver failure; these vesicles, mainly derived from cultured mesenchymal stem cells, hold great translational promise.

Intercellular communication analysis revealed defects in brain-derived neurotrophic factor (BDNF)-TrkB signaling cascade in old NSCs. Carboxypeptidase E (CPE) was found to be highly enriched in NSCs, and played a crucial role in mature/proBDNF balance and adult neurogenesis. Diminishment of CPE with aging resulted in impaired generation of BDNF, thus limiting the neurogenesis in old neurogenic niches.
