In this study, we did not investigate the differences of the secreted factors (secretome) between adult pMSCs and UC-MSCs from newborn babies, but other studies show that as compared with UC-MSCs, the adult AD-MSCs produce more growth factors (e.g., VEGF, insulin-like growth factor, bFBF) and SDF-1 or less pro-apoptotic thrombospondin-1 [62–64]. Here, THBS1 is linked to Alzheimer disease.
