Embryos shape their limbs: a key discovery of "genetic brakes"
Researchers at the Montreal Clinical Research Institute have identified 'genetic brakes'—specifically Polycomb complexes—that regulate gene expression during limb development in embryos. This discovery explains how cells silence specific genes to ensure proper physical formation and prevent congenital malformations.
Why it matters
Understanding these fundamental genetic mechanisms provides critical insights into the origins of developmental disorders and congenital abnormalities.
