Ultrastructural changes in cells of transplanted mammary gland carcinoma at different stages of their development.
The process of development and death of cells of primary mammary gland carcinoma was studied in rats in various hormonal situations, using electron microscopy. It was shown that the death of cancer cells is not preceded by their differential and specific functioning, which is postulated by certain authors. The problem of hormonal induction of the phenomenon of differentiation of malignantly degenerated cells is discussed.
