[Hormone-dependent characteristics of the myocyte cell surface in the human myoma and myometrium cultured in diffusion chambers].

The normal and the pathologically changed human myometrium was cultured in the diffusion chamber implanted in the subcutaneous cellular tissue of the rat. In the absence of hormonal influence the growth of myometrium culture is only insignificant, while no myoma cell growth was found at all. Estradiol stimulates the growth and development of the myometrium culture and the myoma. A combined action of estradiol and progesterone stimulates the collagen formation.
