Fig. 2From: Activation of dopamine receptor D1 promotes osteogenic differentiation and reduces glucocorticoid-induced bone loss by upregulating the ERK1/2 signaling pathwayDex inhibited the differentiation of osteoblasts and reduced D1R expression in vitro. A Representative images of western blots probed with antibodies against ALP, OSX, Runx2, and D1R. B–E Quantification of ALP, OSX, Runx2, and D1R protein levels. n = 3 per group. NS: Not statistically significant, * p < 0.05, ** p < 0.01, vs. the Dex (−) group at the same time point. F Representative images showing immunofluorescence staining of D1R.
