MSCs increase the secretion of angiopoietin-1, keratinocyte growth factor (FGF-7) [63], fibroblast growth factor-2 (FGF-2), vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF) [64,65] and a number of unique proteins and signaling molecules [66] which are pivotal in the restoration of tissue disrupted by COVID-19. The gene discussed is HGF; the disease is COVID-19.
