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 ...
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 ...
Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...
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 ...
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 ...
A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...
Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...
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 ...
