The effects of exosomes on tube formation by HUVECs. (A) HUVECs tube formation was studied by growing cells in Matrigel in M200 medium containing 0, 50, or 100 μg/mL hiPSC-MSC-Exos. Scale bar = 250 μm. Total tube lengths (B) and branch points (C) of HUVECs following growth in M200 medium containing 0, 50, or, 100 μg/mL hiPSC-MSC-Exos for 4, 6, or 18 h. * P < 0.05.
