An enzyme prevents the formation of multiple heads and axes in freshwater polyp Hydra

In the animal kingdom, specific growth factors control body axis development. They are produced by a small group of cells at one end of the embryo to be distributed in a graded fashion toward the opposite pole. Through this, discrete spatial patterns arise that determine the correct formation of the head-foot axis. Researchers have discovered an enzyme in the freshwater polyp Hydra that shapes this process by limiting the activity of certain growth factors.
