Caption: An organ-shaping gene has been found in the microscopic worm Caenorhabditis elegans, or C. elegans for short. The gene and the protein it makes are responsible for shaping the gonad, a complex reproductive organ. Similar genes and proteins are probably at work in other animals, including humans. The new finding by University of Wisconsin-Madison biochemist Judith Kimble and graduate student Robert Blelloch advances the prospect of one day growing complete organs for transplant.
