Figure 5From: Responses of human adipose-derived mesenchymal stem cells to chemical microenvironment of the intervertebral discmRNA expression of aggrecan and collagen-I in ADMSCs under the IVD-like chemical conditions. RT-PCR analysis of aggrecan and collagen-I mRNA levels in ADMSCs cultured for 1 week or 2 weeks under IVD-like chemical conditions. Statistically significant differences were indicated with asterisks, * P < 0.05, ** P < 0.01, *** P < 0.001.Back to article page
