It’s long been known that individual genes play a role in early development, but a new study has shed light on the extent to which these genes are involved. Scientists at the University of California, Los Angeles, have identified nearly 1,000 genes that are essential for the earliest stages of development in mice. The findings provide new insights into how these genes interact and the roles they play in the very earliest stages of life. This could potentially lead to a better understanding of how genetic mutations can cause birth defects and other disorders.
