Directionally migrating eukaryotic cell
WebEukaryotic cells, apart from the cytoskeleton, are distinctive than Prokaryotic cells for having membrane-bound organelles. Organelles speak of a higher level of organization. That requires more space, because there are more and more organelles which need to be able to fit into one cell while not being squashed tightly into each other. There ... Webvance for cell migration in vivo. Our approach involves using non-directionally migrating cells, in this study, primordial germ cells (PGCs) (15), as bioprobes. In many vertebrates and invertebrates, PGCs migrate within the early embryo, using an evolutionarily con-served robust migration mode similar to that of the single-celled
