The myometrium is the middle layer of the uterine wall, consisting mainly of uterine smooth muscle cells (also called uterine myocytes), but also of supporting stromal and vascular tissue. Its main function is to induce uterine contractions.
Because the myometrium of the uterus is comprised of smooth muscle, it stands to reason that CCBs could be effective in suppressing early uterine contractions. Moreover, levels of p21 in cell line HT1 are higher than that of the normal myometrium.
