Figure 4

Histological changes in the TMJ disc and cartilage. (a)–(d) Representative images of H&E-stained slides show the middle part of the TMJ disc and cartilage from Con, CFA, CRP, and groups, respectively. (e)–(h) Representative images of safranin O- and fast green-stained slides involving TMJ discs and cartilage from Con, CFA, CRP, and groups, respectively. (i) Photomicrograph showing the disc thickness measurement method (A: anterior band; In: intermediate zone; P: posterior band). (j) Photomicrograph of cartilage thickness measurement, with a blue line indicating the total cartilage thickness (TC), a yellow line indicating the fibrocartilage layer thickness (FL), and a black line indicating the hypertrophic chondrocyte layer thickness (HL). (k) Statistical results of disc thickness in every group. (l) Statistical results of cartilage thickness in every group. (; ; ).
