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.
Hypothalamic kisspeptin neurons are master regulators of mammalian reproduction. Yamada et al. generated novel Kiss1 (kisspeptin gene)-Cre rats and investigated the developmental changes and sex differences in visualized Kiss1 neurons of Kiss1-Cre-activated tdTomato reporter rats (Yamada et al.; Sex difference in developmental changes in visualized Kiss1 neurons in newly generated Kiss1-Cre rats, p. 227–238). Histological analysis revealed that Kiss1 neurons, which were visualized by tdTomato, were sexually dimorphic in the anteroventral periventricular nucleus (AVPV), arcuate nucleus, and medial amygdala. As shown on the cover page, neonatal AVPV visualized Kiss1 neurons were detected only in males (upper left; compared to the AVPV in neonatal females on the upper right), but a larger number of visualized Kiss1 neurons were detected in the AVPV in females (lower right) than in males (lower left) in adulthood. The Kiss1-Cre and Kiss1-visualized rats could be valuable tools for further detailed analyses on the sexual differentiation and physiological role of kisspeptin neurons.
