HE histological Staining
Representative samples of the control group and histological staining with HE under magnification of 100, 200, and 400 times and labelling of newly formed bone, residual biomaterial, soft tissue, osteoblasts at the boundary between newly formed bone and residual biomaterial, osteocytes in newly formed bone and Howship lacunae in the bone bed with a blood vessel indicating the integration of biomaterials and newly formed bone (Representative samples of the test group and histological staining with HE under magnification of 100, 200, and 400 times and labeling of newly formed bone, residual biomaterial, soft tissue, osteoblasts at the boundary between newly formed bone and residual biomaterial, osteocytes in newly formed bone and Howship lacune in the bone bed with a blood vessel indicating the integration of biomaterials and newly formed bone (Representative samples of the control group and histological staining with HE under magnification of 100, 200, and 400 times and labeled fibroblasts and fibrocytes in the soft tissue and cells of the monocyte–macrophage system around the residual biomaterial, indicating biomaterial degradation (Representative samples of the test group and histological staining with HE under magnification of 100, 200, and 400 times and labelled fibroblasts and fibrocytes in the soft tissue and cells of the monocyte–macrophage system around the residual biomaterial, indicating the decomposition of the biomaterial (
