The pathway of ERK can be mixed up in protein kinase pathway which is activated by mitogen. The adipose-derived stem cells’ osteogenic reaction would be decreased by ERK1/2 signaling pathway inhibition [25]. Nevertheless, Lund et al. [26] pointed that the prohibition of the SNS-032 signaling pathway of ERK1/2 augmented the osteogenic reaction in hMSCs, which may be dependent on the cell type or treatment used. In our research, DHA could promote expression of RUNX2 and the ERK. RUNX2 is a key transcription factor for osteogenesis. However, when using U0126 to inhibit the ERK1/2 signaling pathway, we found that the matrix mineralization and protein expression of RUNX2 were adequately decreased, demonstrating that the pathway of ERK1/2 significantly affects DHA-induced osteogenic differentiation. Another significant pathway that is included in osteogenesis is the Wnt/and SNS-032 ERK signaling pathways existing. Third, we did not SNS-032 conduct an in vivo experiment to prove that DHA promoted fracture healing. In conclusion, our study indicates that DHA has no significant effect on the proliferation of hMSCs but SNS-032 enhances osteogenic differentiation via the signaling pathways of Wnt/as well as ERK1/2 (Figure 6).
