Advances in Female Germ Cell Induction from Pluripotent Stem Cells by Maisumu Gulimiheranmu, Xinjie Wang, Junmei Zhou

“…Female germ cells mainly develop during the embryonic stage and pass through subsequent developmental stages including primordial germ cells, oogonia, and oocyte. However, due to the limitation of using early human embryos as in vivo research model, in vitro research models are needed to reveal the early developmental process and related mechanisms of female germ cells. …”

Effect of genomic regions harboring putative lethal haplotypes on reproductive performance in closed experimental selection lines of Nellore cattle by Gustavo R. D. Rodrigues, Joslaine N. S. G. Cyrillo, Lúcio F. M. Mota, Patrícia I. Schmidt, Júlia P. S. Valente, Eduarda S. Oliveira, Lúcia G. Albuquerque, Luiz F. Brito, Maria E. Z. Mercadante

“…The gene networks were involved in metabolic pathways including ovarian steroidogenesis, oocyte meiosis, and insulin secretion. Matings between carrier dam and carrier sire led to a reduction of up to -203.46% in pregnancy success probability, an increase of 275.15% in probability of pregnancy loss, 295.03% for stillbirth occurrence, and 301.40% for pre-weaning mortality when compared to non-carrier dam and sire matings. …”
