SF upregulates MMP13 expression in hucMSCs via a MAPK-AP1 pathway. A Protein bands and quantitation of their expression in hucMSCs treated with SF. B hucMSCs treated with SF and p38 inhibitor. C hucMSCs treated with SF and Erk1/2 inhibitor. D hucMSCs treated with SF and JNK inhibitor. E hucMSCs nuclei treated with SF and p38 inhibitor. F hucMSCs nuclei treated with SF and Erk1/2 inhibitor. G hucMSCs nuclei treated with SF and JNK inhibitor. Values are presented as mean ± SD. ^#P < 0.05 and ^##P < 0.01 versus NC group; ^*P < 0.05 and ^**P < 0.01 versus SF group. All experiments were repeated at least three times
