The results obtained in histochemical examination of the stroma of mammary gland carcinomas allow to draws the following conclusions. The reaction for alkaline phosphatase proved suitable for detecting proliferation zones in the stroma of mammary gland carcinoma. Proliferation of fibroblasts, myofibroblasts, endothelial cells, and possibly also of other cells is involved.
