Abstract

Epithelial and fibroblast cells were obtained from cultures of amniotic fluid cells. Epithelial cells demonstrated high activities of histidase. In contrast, histidase activity was not detected in fibroblasts derived from the same original culture. This observation indicates that cultures of amniotic fluid cells consist of cells with different biochemical properties as well as morphological characteristics.
