Figure 4From: Responses of human adipose-derived mesenchymal stem cells to chemical microenvironment of the intervertebral discThe proliferation of ADMSCs under IVD-like chemical conditions. MTT assay of ADMSCs cultured for 1 week or 2 weeks under IVD-like chemical conditions. Data were presented as mean ± SD with P < 0.05 for n = 6 (young males) and n = 6 (mature males). Statistically significant differences were indicated with asterisks, *** P < 0.001.Back to article page
