How to build a mouse: Embryo development captured in stunning detail
Researchers have developed new gene-editing techniques to track cell development in mouse embryos with unprecedented precision. This method allows scientists to map lineage and cell fate in mammals, overcoming previous limitations in observing complex biological growth.
Why it matters
This breakthrough provides a foundational tool for understanding mammalian development and disease, potentially revolutionizing how we study organ formation and genetic disorders.

‘Cell recorders’ based on gene editing have captured mouse development in unprecedented detail.
Two independent teams of scientists published the findings today in Science and in Cell . One team recorded the cell-by-cell development of a two-week-old embryo from a single fertilized egg 1 , and the other captured most of the cell divisions in embryos as organs formed 2 .
