Fig. 2From: The combinatory effect of sinusoidal electromagnetic field and VEGF promotes osteogenesis and angiogenesis of mesenchymal stem cell-laden PCL/HA implants in a rat subcritical cranial defectMorphology of rBMSCs observed under microscope after 1 week induction of SEMF (1 mT, 15 Hz, 4 h/day) and VEGF (50 ng/ml). Scale bar = 100 μm (a). Proliferation of MSCs treated with SEMF and VEGF was tested using CCK-8 at 1, 4, and 7 days (b). Relative ALP activity of rBMSCs inducted by SEMF and VEGF at 1, 4, and 7 days (c). Data represents mean ± SD (n = 3, *p < 0.05)Back to article page
