Key result
Injection of cortical bone stem cell-derived exosomes at the onset of reperfusion elicited cardioprotection by decreasing small nucleolar RNA signaling within cardiac fibroblasts.
Why the study?
Does stem-cell-derived exosome therapy elicit cardioprotection in post-ischemia-reperfusion wounded hearts?
Does stem-cell-derived exosome therapy elicit cardioprotection in post-ischemia-reperfusion wounded hearts?
Stem cell-derived exosomes provide cardioprotection in ischemia-reperfusion injury by modulating fibroblast activation via decreased snoRNA signaling.

May support exosome cardioprotection in reperfusion injury; leaves open human translation.
Our work is noteworthy due to the identification of factors within stem cell-derived exosomes (dEXOs) that alter fibroblast activation through the hereto-unknown mechanism of decreasing small nucleolar RNA (snoRNA) signaling within cardiac fibroblasts. The study also shows that the injection of stem cells or a stem-cell-derived exosome therapy at the onset of reperfusion elicits cardioprotection, emphasizing the importance of early treatment in the post-ischemia-reperfusion (I/R) wounded heart.

Schena et al. (2021) studied Myocardial ischemia-reperfusion and cardiac remodeling. Cortical bone stem cell-derived exosomes (dEXOs) was evaluated on Cardioprotection and fibroblast activation. Injection of cortical bone stem cell-derived exosomes at the onset of reperfusion elicited cardioprotection by decreasing small nucleolar RNA signaling within cardiac fibroblasts.
