Histoenzymologic study of hyalocytes in tissue culture.
The mitochondrias of the hyalocytes contain lactic dehydrogenase but no glucose-6-phosphate dehydrogenase, so that only aerobic respiration is possible. Among the lysosomal enzymes, acid phosphatases and beta-glucuronidase are found, the latter facilitating the turnover of the hyaluronic acid. There is no galactosidase, as the hyaluronic acid of the vitreous does not contain galactose.
