This part of early embryonic development transforms a simple ball of cells and begins to define cell fate and the body axis. In a study published in <i>Science</i> magazine in March 2012, NIGMS grantee Bob Goldstein and his research group studied how contractions of actomyosin filaments in <i>C. elegans</i> and <i>Drosophila</i> embryos lead to dramatic rearrangements of cell and embryonic structure. This research is described in detail in the following <a href=http://www.sciencemag.org/content/335/6073/1232.abstract target="_blank"> article</a>: "Triggering a Cell Shape Change by Exploiting Preexisting Actomyosin Contractions." In these images, myosin (green) and plasma membrane (red) are highlighted at four timepoints in gastrulation in the roundworm <i>C. elegans</i>. The blue highlights in the top three frames show how cells are internalized, and the site of closure around the involuting cells is marked with an arrow in the last frame.
