Fig. 3From: Autologous cell-coated particles for the treatment of segmental bone defects—a new cell therapy approachOsteogenic gene expression after osteogenic induction for 2 days. a qPCR analysis of early osteogenic markers ALP, SP7 (Osterix), and DLX5 gene expression at day 2 after osteogenic induction. b Time course of the late osteogenic markers SPP1 and IBSP. Values were normalized to day 0. Real-time analysis was done using ΔΔCt method and shown as fold change vs. control group and normalized to the RPLP0 housekeeping gene. Mean ± SEM (n = 6). c FACS analysis revealed that ~ 50% of the cells express SP7 protein after 2 days of osteogenic induction in the 3D systemBack to article page
