MSC-Exos increase HUVEC SPF and PIndex. HUVECs were cultured for 24 h with 50 µg/mL of MSC-Exos or MSC-Exo + NPs. The DNA content of the HUVECs was measured by propidium iodide staining using flow cytometry. a FACS plots representative of one of three experiments. b Averaged SPF and PIndex of three independent experiments. Bar = SD. *P < 0.05 vs. HUVEC group
