(Weizmann Institute of Science) Weizmann Institute scientist Prof. Naama Barkai and her colleagues have developed a mathematical model to describe interactions that occur within genetic networks of an embryo, answering the age-old question of how half embryos are able to maintain their tissues and organs in the correct proportions despite being smaller than a normal sized embryo.

Understanding the processes that govern embryonic cell development, may lead, in the future, to scientists being able to repair injured tissues.
