Japanese team identifies molecule controlling embryonic growth in fish

A group of researchers has identified a molecule regulating the normal growth of fish embryos that clears maternal genes and switches to their own, according to a study published in the U.S. Science magazine on Thursday.
Kunio Inoue, assistant professor of developmental biology at Kobe University, and other researchers in the team believe that the findings may help resolve the mechanism controlling the early phase of life.
