Figure 2From: Human amniotic fluid-derived and dental pulp-derived stem cells seeded into collagen scaffold repair critical-size bone defects promoting vascularizationRadiological analysis of rat calvariae dissected 4 or 8 weeks after surgery. Images are representative of (A) intact bone (left panel) and the bone healing in the cranial defects (right panel), (B) scaffolds alone, and scaffold seeded with (C) dental pulp stem cells or (D) amniotic fluid stem cells.Back to article page
