Differentiated cells stained positively with Alizarin Red (Figure 4A) and both RUNX2 and ALP genes increased during differentiation of Normal-MSCs (P < 0.04), however, ALP (P = 0.02) but not RUNX2 (P = 0.96) increased during differentiation of IUGR-MSCs. This evidence concerns the gene RUNX2 and fetal growth restriction.
