The road to gene manipulation in the mouse: Jean Brachet Memorial Lecture of the International Society of Differentiation (delivered June 21, 2023 at Cold Spring Harbor Laboratory).

Genetic manipulation in mammals has progressed rapidly in the past decade with the advent of CRISPR-Cas gene editing tools, promising profound impacts on the understanding of human development, health and disease. However, many years of research in divergent fields of experimental embryology, genetics, reproduction, molecular biology and transgenic technology laid the groundwork and have played critical roles for this progress. This article details various threads of research and the central role of the laboratory mouse that came together in reaching this point, all from the perspective of a scientist whose research was deeply immersed in the field.
