Background: Though plausible candidate adhesion systems have been identified, current knowledge of embryo-maternal attachment in human is limited by the inability to conduct well-controlled functional investigations. We have sought a viable medium-throughput model for the identification and functional assessment of molecular markers in the initial epithelial phases of implantation. An ideal mod...
The Fas-Fas ligand (L) system is one of the major signalling pathways to induce apoptosis in various cells and tissues. The aim of this study was to investigate the expression of the Fas-Fas L system in rat and human oocytes and preimplantation embryos. We determined the expression of Fas and Fas L mRNA of rat oocytes and embryos up to the blastocyst stage, and of human embryos at the 2- or 4-c...
Purpose: To compare effects of polarized epithelial monolayer prepared from human oviduct and uterus on mouse one and two-cell embryo development. Materials and Methods: Human oviduct and endometrial tissue was obtained from patients who had undergone total hysterectomy. The epithelial cells were isolated from tissue and cultured on extracellular matrix (ECM) Gel coated Millipore filter insert...
