The expression of osteogenic and chondrogenic genes in VB-BM versus IC-BM MSCs.

A. The gene expression levels during the osteogenic differentiation of VB-BM and IC-BM MSCs (4 donor-matched pairs) were assessed using TaqMan real time PCR. The gene expressions of samples collected at 1, 2 and 3 weeks of osteogenesis were calculated relative to undifferentiated cells. B. The gene expression levels during the chondrogenic differentiation of VB-BM and IC-BM MSCs (4 donor-matched pairs) were assessed using TaqMan real time PCR. The gene expressions of samples collected at 1, 2 and 3 weeks of chondrogenesis were calculated relative to undifferentiated cells. *: p<0.05. Dotted lines indicate the basal expression level of genes in undifferentiated cells.
