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.

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 ...

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment.

The International Society for Stem Cell Research (ISSCR) Embryo Models Working Group has released updated recommendations for the oversight and regulation of stem cell-based embryo models (SCBEM ...
