As shown in Figure 7, there was a tendency towards a decrease in basic fibroblast growth factor (bFGF) and neurotrophin-3 (NT-3) mRNA expressions in the diabetes + vehicle rats and an increase in nerve growth factor (NGF), bFGF, and NT-3 mRNA expressions in the diabetes + DPSC-SFs rats and an increase in NT-3 mRNA expression in the diabetes + DPSCs rats. This evidence concerns the gene NGF and diabetes mellitus.
