Figure 6From: Silencing Dkk1 expression rescues dexamethasone-induced suppression of primary human osteoblast differentiation Primary human osteoblasts transfected with siRNA targeting Dkk1 expression or scrambled control RNA. Dkk1 protein expression assessed using ELISA to confirm knockdown. **p < 0.01, ***p < 0.001 versus transfection control and scrambled control.Back to article page
