Figure 7From: Bone morphogenetic protein 2 gene transduction enhances the osteogenic potential of human urine-derived stem cells Human derived OCN was detected by immunostaining after six weeks. (a) USCs/β-TCP; (b) Lentiviral-BMP2 transduced USCs/β-TCP. The arrows indicate the positive staining of OCN. Scale bar = 100 μm. B-TCP, β-tricalcium phosphate; BMP2, bone morphogenic proteins 2; OCN, osteocalcin; USCs, urine-derived stem cells.Back to article page
