Fig. 5From: Co-expression of 1α-hydroxylase and vitamin D receptor in human articular chondrocytesWestern blots targeting VDR and 1α-hydroxylase in chondrocyte suspension cultures (a) and monolayer cultures (b) exposed to IL-1β (10 ng/mL) or 1α,25(OH)2D3 (10−8 M) for 24 h; controls are untreated cells. Graphs show the corresponding protein expression by densitometry in samples from three different donors. Error bars represent 95% CIBack to article page
