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 ...

Lab-grown embryo models are getting more realistic. Scientists are getting more concerned
Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...
Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late developmental stages but resemble one another more during mid-embryogenesis, a ...
University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development - including the ...
Live imaging of embryos at different stages. Chromosomes are labeled in magenta. 4-cell sister blastomeres are shown, along with 3D-reconstructed images of 2-to-4-cell and 4-to-8-cell divisions.
