Elastic cartilage

Elastic cartilage from the pinna of the ear is stained with a dye specific for elastin. The abundant elastic fibers and additional elastic material in the central regions of the cartilage obscure individual fibers. However, they can be readily seen on the edges. Note the numerous chondrocytes but infrequent isogenous groups. 200x
