Changes in endometrial vascularity during implantation and pregnancy in the rabbit

Changes in endometrial vascularity during implantation and pregnancy in the rabbit Sixty‐five pregnant rabbits were autopsied at different stages of pregnancy 2 to 28 days post coitum (p.c.). The vascularity of the endometrium and placenta was studied using intervascular injections of neoprene latex cast, by clearing injected specimens and by the study of frozen and paraffin embedded sections. At 6 days p.c. the implantation sites were identified; the endometrium at the inter‐conceptus was similar to that during pseudopregnancy. The subepithelial capillary plexus increased in thickness, reaching a maximum at 6–11 days p.c. Marked endometrial branching occurred 10 days p.c. After 15 days p.c. the endometrium formed a thin irregular layer. Most of the endometrial epithelial cells showed cytoplasmic projections at 6 days p.c. and were transformed into syncytial epithelial cells 8 days p.c. At 24–28 days p.c. the conceptus and interconceptus areas were unidentifiable. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png American Journal of Anatomy Wiley

Abstract

Sixty‐five pregnant rabbits were autopsied at different stages of pregnancy 2 to 28 days post coitum (p.c.). The vascularity of the endometrium and placenta was studied using intervascular injections of neoprene latex cast, by clearing injected specimens and by the study of frozen and paraffin embedded sections. At 6 days p.c. the implantation sites were identified; the endometrium at the inter‐conceptus was similar to that during pseudopregnancy. The subepithelial capillary plexus increased in thickness, reaching a maximum at 6–11 days p.c. Marked endometrial branching occurred 10 days p.c. After 15 days p.c. the endometrium formed a thin irregular layer. Most of the endometrial epithelial cells showed cytoplasmic projections at 6 days p.c. and were transformed into syncytial epithelial cells 8 days p.c. At 24–28 days p.c. the conceptus and interconceptus areas were unidentifiable.
