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 ...

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 ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

The work appears in Cell. "Understanding embryo implantation and embryo development just after implantation has significant clinical relevance as these stages are particularly prone to failure," said ...

"Understanding embryo implantation and embryo development just after implantation has significant clinical relevance as these stages are particularly prone to failure," said Dr. Peter Rugg-Gunn, ...

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 ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...
