image: Embryonic cells of a roundworm. Plasma membranes are purple, highlighting the boundaries where cells meet, and myosin motors are marked in yellow. The embryo has 26 cells at this stage, and two of the cells are about to become internalized, moving from the surface to the interior. This image relates to a paper that appeared in the Feb. 9, 2012, issue of Science Express, published by AAAS. The paper, by M. Roh-Johnson at the University of North Carolina at Chapel Hill in Chapel Hill, N.C., and colleagues was titled, "Triggering a Cell Shape Change by Exploiting Pre-Existing Actomyosin Contractions." view more
