Sequential fluorescent labeling of bone formation and mineralization. Bone formation and mineralization in the defect area of the non-irradiated (a) and irradiated (b) rats at 8 weeks. Red, green and yellow represent labeling by Alizarin Red S (AL), calcein (CA) and tetracycline hydrochloride (TE). The upper panels show the overall image of each group (×15).
