Figure 6 (A) The newly formed cartilage tissue is highlighted in dark blue and is shown with a white star. The black star in this picture shows the fibrous connective tissue that has not healed. The presence of isogenous groups indicates the normal histological structure of the cartilage tissue. The irregularity of the cartilage surface (white arrowhead) in contrast to Groups C and D indicates that there is no healing in this tissue. (B) The newly formed cartilage tissue is marked with a dark blue color and is shown with a white asterix. The black asterix in this picture shows the fibrous connective tissue that has not healed. The presence of isogenous groups indicates the normal histological structure of the cartilage tissue. The smoothness of the cartilage surface (white arrowhead) indicates healing in this tissue. (C) The newly formed cartilage tissue is marked with a dark blue color and is shown with a white asterix. The presence of isogenous groups indicates the normal histological structure of the cartilage tissue. The smoothness of the cartilage surface (white arrowhead) indicates healing in this tissue. The black arrow clearly shows the prominence of the tidemark. (D) The newly formed cartilage tissue is marked with a dark blue color and is shown with a white asterix. The presence of isogenous groups indicates the normal histological structure of the cartilage tissue. The smoothness of the cartilage surface (white arrowhead) indicates healing in this tissue. The black arrow clearly shows the prominence of the tidemark.
