Fig. 4From: Polycaprolactone nanofiber scaffold enhances the osteogenic differentiation potency of various human tissue-derived mesenchymal stem cellsThe expression of osteo-specific genes ALP, BMP-2, RUNX2, and COLL1A1 among three kinds of human MSCs. a–d Real-time PCR was employed to examine the expression of osteo-specific genes ALP, BMP-2, RUNX2, and COLL1A1 in UC-MSC, BM-MSC, and AD-MSC on PCL nanofiber scaffolds. * P < 0.05; ** P < 0.01; *** P < 0.001.
