Bone features of 12-week-old female transgenic mice (Tg) with Epor deletion in osteoblasts and littermate controls (wt) with 10 daily administration of recombinant EPO. (A) 3D images of trabecular bones of wt and Tg female mice receiving 1200 IU/kg of EPO for ten days. (B-G) Micro-CT quantitation of trabecular BMD, trabecular BV/TV, number, spacing, thickness and connectivity density. (H-J) Micro-CT quantitation of cortical BMD, BV and thickness. (n=4–6/group, *p<0.05, **p<0.01).
