Abstract
We hypothesize that adhesion molecules known to be involved in intrauterine embryo implantation are also involved in tubal embryo implantation. We also hypothesize that the embryo, by producing hCG, may increase expression of tubal adhesion molecules. Thus, we examined expression of CD44, osteopontin (OPN), L-selectin ligand (LSL) and trophinin (TRO) by human fallopian tube ex vivo or cultured in the presence and absence of hCG. Since methods for tubal culture are not well established, the effect of time in culture in the presence and absence of fetal calf serum (FCS) was also investigated.
