Barcelona, Spain: For the first time in the world scientists have succeeded in developing human embryonic stem cells (hESCs) from a single cell, or blastomere, of a 4-cell stage embryo ...

During embryonic development, thousands of cells divide and move collectively to sculpt the main body axes. Understanding the ...

For the first time in the world scientists have succeeded in developing human embryonic stem cells (hESCs) from a single cell, or blastomere, of a 4-cell stage embryo, the 24th annual conference of ...

The 4-cell embryo can now be seen as a transitional stage during which uniform DNA replication becomes sequential, while still showing slow fork movement characteristic of 1- and 2-cell embryos.

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.

trained a neural network to predict the precise developmental time for every cell. "Even though the collected samples contained embryos with slightly different ages within a 2- or 4-hour time ...

Researchers use these spatially organized colonies to study gene expression and the role of cell density in embryo development. (4) Post-Implantation Embryo Models: Scientists differentiated PSCs ...
