title: Development. A degrading way to make an organ.
abstract: Working out how organs form during embryonic development is a fascinating area of research. In a witty Perspective, Jeff Hardin describes new findings (Nishiwaki et al.) that reveal the many intricate steps needed for gonads to form in the worm C. elegans. Two key players, GON-1 and MIG-17, are metalloproteases that may help migration of distal tip cells by degrading extracellular matrix components.
