it has been concluded from the studies on the activity and location of atpase and 5-nucleotidase in mammary and gastric tumours that some neoplasms of the mammary gland and stomach showing a high atpase activity are histochemically related , in the former case , to the lobular myoepithelium and in the latter case , to non-differentiated cells of gastric glands which acquired a capacity for intestinal metaplasia and preserved it in the course of malignant transformation .
