Epigenetic reprogramming during the maternal‐to‐zygotic transition
MedComm, 2023 After fertilization, sperm and oocyte fused and gave rise to a zygote which is the beginning of a new life. Then the embryonic development is monitored and regulated precisely from the transition of oocyte to the embryo at the early stage of ...

Birth of Normal Mice Following Round Spermatid Injection Without Artificial Oocyte Activation
Journal of Reproduction and Development, 2011 For fertilization using round spermatid injection (ROSI) in mice, oocytes need to be artificially preactivated because of the lack of oocyte-activating capacity in round spermatids of this species. However, when round spermatids were frozen-thawed before microinjection, 11-71% of injected oocytes developed into 2-cell embryos without any artificial ...

Sperm Sexing in Selected Animals and Humans: Methods, Applications, and Future Prospects
Andrology, EarlyView.ABSTRACT Background Sperm sexing is a technique that enables the selection of offspring sex by sorting spermatozoa based on their sex chromosomes. This technology has gained increasing attention due to its potential applications in both animal breeding and human‐assisted reproduction.

Analysis of Human Uniparental Embryonic Stem Cells Reveals New Putative Imprinted Loci
Cell Proliferation, EarlyView.To identify novel imprinted genes, parthenogenetic, androgenetic and biparental human embryonic stem cells and their differentiated neural progenitors were analysed by methylome and transcriptome profiling. This approach uncovered 12 putative novel imprinted genes, including a clustered region on chromosome 19, expanding the current catalogue of ...

Journal of Fish Biology, EarlyView.Abstract The Malabar red snapper (Lutjanus malabaricus) is a high‐value tropical marine species receiving growing attention for aquaculture development in Singapore and Southeast Asia. At present, seed production relies primarily on uncontrolled mass spawning in sea cages, a practice that lacks consistency, biosecurity and control of genetic ...

Women in space: A review of known physiological adaptations and health perspectives
Experimental Physiology, EarlyView.Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.
