The identification of endplate chondrocytes. (a) Endplate chondrocytes were stained by HE. HE staining showed that majority of endplate chondrocytes were polygonal or spindle-shaped. (b) Endplate chondrocytes were labeled by toluidine blue. The cytoplasm of endplate chondrocytes exhibited blue after being labeled by toluidine blue. (c) Immunofluorescence staining for type II collagen. Type II collagen was distributed in the cytoplasm of endplate chondrocytes.
