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.

In their new study, the team of RIKEN BDR researchers set out to characterize the nature of the DNA replication process in early-stage embryos. They used their homemade single-cell genomics ...

During animal development, cells divide and arrange themselves in a coordinated way, eventually forming the embryo. The cells communicate with one another during this process through cell-surface ...

Stem cell-based embryo models (SCBEMs) are three-dimensional biological structures that mimic aspects of early human embryo development. They can be created in the lab from stem cells, and can ...

Nr1h2 activation was sufficient to enhance the functional and genetic fidelity of stem cell-derived embryo models. To test Nr1h2's potential, the team treated embryonic stem cells with the small ...

New report urges guidelines — and some restrictions — on stem cell-based embryo models. The recommendations focus on the U.K. but could be seen as a template in other nations.

Researchers from Japan and France have successfully reconstituted the development of mouse egg cells, known as oocytes, from ...

Eight healthy babies were born in Britain with the help of an experimental technique that uses DNA from three people to help ...

During embryogenesis, the initially fertilized egg divides, as do each new set of daughter cells. By the third day after fertilization, an embryo has undergone three divisions and contains 16 cells.
