Intravital fluorochrome labeling. Most of the callus was created during the early, calcein green (CG)-labeled period in endosteal and dorsal regions. P values of <0.05 were considered to be significant (* value differs significantly from CG area of same group; ^∆ value differs significantly from alizarin red area of same group). The last chart presents the total callus for all stained periods
