...Helmuth Vorherr; Ute F. Vorherr In rats fertilized during the 1 st or 2nd day postpartum (second consecutive pregnancy), suckling induces intrauterine blastocyst dormancy and delays implantation for 8–22 days. In spite of this relatively long time of blastocyst dormancy, associated with greatly...

...David R. Garris The ultrastructural aspects of the appositional phase of interstitial blastocyst implantation in the guinea pig have been investigated using scanning and transmission electron microscopy. Blastocysts measured 28–34 µm in diameter and were encased in the zona pellucida. Trophoblast...

...D.A. Tutton; D.H. Carr Pre-implantation blastocysts or trophoblast, obtained from ectoplacental cones, were transferred to the right oviducts of both pregnant and nonpregnant mice. Blastocysts which remained within the oviductal lumen did not show evidence of further differentiation...

...Amos Fein; Vladimir Toder; Laslo Nebel Preimplantation rat blastocysts were examined in vitro for concanavalin A agglutinability and antigenic properties on the 5 th day of development after flushing and after 24 h in culture, following regional differentiation. Differences were found between...
