FIG. 4.

MicroCT analysis of regenerated bone. (A) Representative microCT images. The BMP2 group regenerated bone localized to the inner module, and EPO+BMP2 regenerated bone in the outer module pores as well as in the inner module. Red arrow=bone, red circle=pore space, red star=PCL scaffold. (B) EPO+BMP2 resulted in significantly more total regenerated bone compared with the BMP2 group at 4 weeks (*p<0.05). MicroCT, microcomputed tomography. Color images available online at www.liebertpub.com/tec
