Evaluating the long-term effect of space radiation on the reproductive normality of mammalian sperm preserved on the International Space Station Open
The effect of space radiation on offspring was evaluated using mouse freeze-dried spermatozoa preserved on the Space Station.

New cellular imaging of oocytes and preimplantation embryos using Lumitein™: Evaluation of oocyte quality and new information on protein dynamics within the perivitelline space during the one-cell oocyte stage in mice Open
The extracellular matrix between the oocyte and zona pellucida (ZP) plays an important role in mammalian fertilization and preserves the specific environment of the perivitelline space (PVS) during the development of a preimplantation embr…

A heterozygous deficiency in protein phosphatase Ppm1b results in an altered ovulation number in mice Open
Ppm1b, a metal‑dependent serine/threonine protein phosphatase, catalyzes the dephosphorylation of a variety of phosphorylated proteins. Ppm1b‑/‑ mouse embryos die at the fertilized oocyte stage, whereas Ppm1b+/‑ mice with a C57BL/6 backgro…

Non-suckling starvation of neonatal mice promotes primordial follicle formation with activation of ovarian autophagy Open
Around the time of oocyte meiotic arrest, germ cell nest breakdown occurs, and primordial follicle (PF) formation is initiated at the perinatal stage. Recently, autophagy was implicated in this process. Autophagy is induced by nutrient sta…
