Scientists have uncovered a new way embryonic cells divide when conventional mechanisms fail. Cell division underpins all ...

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 ...

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 ...

New findings offer insight into why some embryos fail to develop past zygotic genome activation (ZGA), pointing to an unexpected root of human infertility. A critical point in early development is ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...

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 ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

Over the past year or two, we have been exploring what we termed the origins—or the embryology—of human development. We examined the three pillars of development: Feelings (Affects), Language, and ...
