Fig. 6From: 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 defectThree-dimensional reconstruction images (a) of the defect sites by micro-CT in different groups at 4 and 12 weeks. BV percentage (b) and BMD in the implanted scaffolds (c) were quantified (*p  < 0.05 compared with the control group, #p  < 0.05 compared with the co-inducted group)Back to article page
