Aims and Scope

The Journal of Reproduction and Development (JRD) is an international, peer-reviewed Open Access publication, and the official journal of the Society for Reproduction and Development. In six issues per year, JRD publishes basic studies of reproductive biology in vertebrates, including gametogenesis, early embryonic development, placenta development, implantation, reproductive endocrine function and reproductive organ development. JRD also welcomes applied and clinical studies that contribute to the control of reproduction in wild, domestic and laboratory animals, and to the development of new technology to address issues in the field of reproduction. Human clinical case reports are not published by the journal.

Cover Story:

To understand the cellular processes associated with non-invasive mode of conceptus implantation to the maternal endometrium, Yamada et al. observed the conceptus implantation process via adhesion of trophoblast cells to the uterine epithelium (Yamada et al., Epithelial-mesenchymal transition and bi- and multi-nucleated trophoblast cell formation in ovine conceptuses during the peri-implantation period, pp. 110–117). Similar to human syncytiotrophoblast, ruminant trophoblasts form bi- and multi-nucleated trophoblast cells. Using pregnancy associated glycoproteins (PAGs) specific antibody, bi- and multi-nucleated trophoblast cells in cross sections of day 21 ovine uteri (day 0 = day of estrus), including elongated conceptuses, were observed, and it was found that bi- and multi-nucleated trophoblast cells existed on the uterine epithelium or next to the uterine stroma. These results suggest that the formation of bi- and multi-nucleated trophoblast cells facilitates the placental formation in ruminants.
