X-ray slice and histological sections. (A) X-ray slice of 12 weeks after BMSCs are transplanted into nude mouse indicates that high density calcified shadow is detected in experimental side, but not detected in control side (indicated by the arrow). (B) Histological section of experimental side with HE staining indicates that mature bone tissue can be detected between muscular tissues (×100). (C) Histological section of control side with HE staining indicates immature bone and cartilage tissue between muscular tissues (×100). (D) Bone tissue in control side appears as green fluorescence under the fluorescence microscope.
