A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

A research team led by Associate Professor Hirofumi Nishizono and graduate student Masaki Kato from the Research Support ...

Around eight days after fertilization, the human embryo implants in the endometrium (the tissue that lines the uterus). After implantation, it enters a developmental phase that is not well understood ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive – particularly for egg-laying ...

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...

By Dr. Priyom Bose, Ph.D. A newly revealed “aging cliff” in sperm RNA marks a conserved molecular transition from youth to later life, offering fresh insight into how a father’s age may influence the ...

Infertility is a major healthcare concern. Understanding the molecular regulators governing fertilization, early embryonic ...
