Figure 2: The effect of neurosteroid hormones on the oligodendroglial differentiation of adult hMSCs. At the most effective concentrations (i.e. 100nM for E2 and DHT and 250nM for PROG; *p<0.01), ratios for the increased expression of A2B5 +ve cells (A) and the decreased expression of nestin +ve cells (B) were calculated in comparison with hormone-deficient (standard) cultures.
