Ampullae explanted from mice at different stages of the estrous cycle were able to maintain the development of zygotes transferred to them in organ culture. A cyclical variation was observed; the maximum number of zygotes developed into blastocysts within ampullae explanted at metestrus 1, and the l

Abstract
Explanted oviducts from 13β and 16βday embryonic female chicks responded to estradiol (1 to 4 ΞΌg/ml) in the culture medium by forming a thickened epithelium folded into crypts and containing goblet cells and by development of the stroma. In medium containing 3 ΞΌg/ml estradiol and 0.125 ΞΌg/ml hydrocortisone, 13βday embryonic oviducts exhibited further development: The columnar epithelial cells formed cilia and tubular glands were formed.

Successful development of porcine embryos from the one-cell stage to the blastocyst stage has been accomplished using mouse oviducts in organ culture. One-cell embryos were transferred to mouse oviducts maintained in organ culture and were cultured for 6 days. Control embryos from each donor pig wer
## Abstract This study provides a quantitative analysis of the active movements of the chick embryo and of the contractions of the amnion over the entire developmental period of 21 days. Four types of embryo movements are distinguished. The motor activity of the embryo shows two characteristic peak
