The sham (ldlr−/− high-fat fed) mice had reduced osteoblast number, surfaces, and bone formation rate (BFR) in the distal femoral metaphysis. BFR per osteoblast (BFR/Ob) was decreased in the sham mice. Chronic kidney disease (CKD) stimulated osteoblast number (Ob.N.) per bone length (BL) and osteoblast surface per bone surface (Ob.S./BS). There was a trend of CKD to increase BFR/BS. BFR/Ob was decreased by CKD. RAP-011 treatment reversed the effects of CKD on osteoblast numbers and surface, decreased BFR/BS, and increased BFR/Ob. **P < 0.01 for comparisons between wild type (WT) and sham, between sham and chronic kidney disease mice treated with vehicle (CKD V), and between CKD V and CKD R. CKD R, CKD+RAP-011.
