A Micro-CT images of the knee joints. B BMD and BV/TV. C ALP-stained cells in tendon to bone interface (400× magnification). Black arrows indicated the ALP-positive cells. D, E The expression of OCN and OPN was assessed by immunohistochemistry (800× magnification). Black arrows indicated the OCN and OPN-positive cells in tendon to bone interface. #p < 0.05, ##p < 0.01; NS not significantBack to article page
