Ultrahistochemistry of matrix vesicles in elastic cartilage.
Matrix vesicles in the elastic cartilage of epiglottis were negative for acid phosphatase, alkaline phosphatase, and ATPase. This is in agreement with the very rare occurrence of mineralization of elastic cartilage. Only the lysosomes of the chondrocytes showed a positive reaction for acid phosphatase, and a positive reaction for alkaline phosphatase and ATPase was found in relation to the cells of the perichondrium.
