Effect of hWMSCs and endothelial-differentiated hWMSC transplantation in a wound-healing model. A) Representative images of wounds at day 1 (top panels) and 12 (lower panels) after injury and subcutaneous injection of hWMSCs, hWMSC trans-differentiated into endothelial cells for 14 days (hWMSC-End14d) or 30 days (hWMSC-End30d), or control (PBS). B) Wound healing quantified in PBS (○), hWMSC (•), hWMSC-End14d (□) or hWMSC-End30d (▪) treated mice (n = 5 independent experiments, in duplicate). Values are expressed as mean±S.E.M, +P<0.05 in hWMSC-End30d v/s hWMSC, hWMSC-End14d, at the corresponding time; **P<0.03 in hWMSC-End30d v/s PBS; *P<0.001 in hWMSC-End30d v/s PBS; # P<0.01 in hWMSC-End30d v/s PBS.
