Effect of iPSC-derived megakaryocytes and platelets on gene expression of HUVEC
Platelet-rich plasma (PRP), which is prepared by concentrating platelets in autologous blood, shows efficacy in chronic skin wounds via multiple growth factors. However, it exhibits heterogeneity across patients, leading to unstable therapeutic efficacy. Human induced pluripotent stem cell-derived megakaryocytes and platelets (iMPs) are capable of providing a stable supply, holding promise as materials for novel therapies. Thus, we evaluated the effect of iMPs on wound healing in vitro. iMPs specifically released FGF2 and exhibited superior enhancement on HUVEC proliferation compared to PRP. RNA-seq revealed that iMPs induce polarization to stalk cells and enhance ANGPTL4 gene expression in HUVECs. These mechanisms were suggested to provide the superior effects of iMPs.
