Genomic Insights into the Origin, High Fecundity and Environmental Adaptation of Hu Sheep
Advanced Science, EarlyView.The Hu sheep diverged from the Small‐tailed Han sheep ≈1330 years ago, and subsequently migrated from northern to warm and humid southern regions. The genes BMPR1B, UNC5C, and GRID2 play a synergistic role in the superior reproductive traits of Hu sheep.

From Skin Cells to Ovarian Follicles? [PDF]
Cell Cycle, 2006 Generating oocytes from cells derived from skin in vitro may provide a valuable model for identifying factors involved in germ cell formation and oocyte differentiation. In addition, the "oocytes" produced could potentially be useful for therapeutic cloning, and thus offer new possibilities for tissue therapy.

Advanced Science, EarlyView.Meiosis is a specialized form of cell division that has different regulation and mechanisms with mitosis in numerous aspects. Particularly, meiosis I is unique and occurs only in germ cells to separate homologous chromosomes. Thus, determining how this unusual chromosome segregation behavior is established is central to understanding germ cell ...

Initial and Cyclic Recruitment of Ovarian Follicles* [PDF]
Endocrine Reviews, 2000 AbstractMammalian ovaries consist of follicles as basic functional units. The total number of ovarian follicles is determined early in life, and the depletion of this pool leads to reproductive senescence. Each follicle develops to either ovulate or, more likely, to undergo degeneration.

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT This study aims to elucidate the role of the ZSWIM7 gene in the etiology of infertility, focusing on its potential association with premature ovarian insufficiency and azoospermia. We investigated an 18‐year‐old female patient who presented with primary amenorrhea, hypoplasia of the uterus and ovaries, Tanner stage II breast and pubic hair ...

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.ABSTRACT Women with the FMR1 premutation (FXpm) are at heightened genetic vulnerability for depression, with risk compounded by the stressors of parenting a disabled child. Although risk factors persist as FXpm women age, depression in FXpm mothers during midlife and old age is poorly characterized. This study used an accelerated longitudinal design to

Stromal Senp1 promotes mouse early folliculogenesis by regulating BMP4 expression
Cell & Bioscience, 2017 Background Mammalian folliculogenesis, maturation of the ovarian follicles, require both growth factors derived from oocyte and surrounding cells, including stromal cells.

A comparative study of human ovarian tissue xenotransplantation in two different strains of rats
Animal Models and Experimental Medicine, EarlyView.The study involved performing ovariectomy on female Hooded and Wistar rats 14 days prior to transplantation. Following ovariectomy, the rats received cyclosporine starting five days before surgery to suppress the immune response and prevent graft rejection.
