New callus structure at days 14 and 42 after fracture as assessed by micro-CT. (A1, B1) Representative micro-CT 3D reconstructed images of newborn callus at day 14 after fracture (original bone removed). (A2, B2, C) Representative micro-CT 3D reconstructed images at day 42 after fracture. Callus with BMSCs, AMD3100, and BMSCs or saline injected at day 1 (A1, A2), 7 (B1, B2), and 14 (C) post-fracture. (D) The region of interest (highlighted in green) is the newborn callus volume excluding the original cortical bones and the medullary canal volume
