Contractility of Myometrial Transplants
Long-term observation of activity of the myometrium during pregnancy, parturition, and Puerperium in the woman is for obvious reasons difficult to carry out. The individual factors that might influence the initiation of parturition are not possible to study in situ, as the tissue is continuously subject to changes of mechanical, hormonal, and nervous character. In vitro studies of isolated strips of myometrium have rendered information of great importance, but this technique gives only an impression of the immediate situation and never of the preceding or following states of the same tissue. Therefore, the ideal system would permit in vivo study of individual factors having myometrial influence. The technique of grafting seems to have been overlooked for its possibilities in the study of the physiology of the myometrium.
