Image B Both Stem Cells (IMAGE) University of Oxford Caption (top panels) Both stem cells (green, detecting the gene expression of smedwi-1) and their daughter cells (magenta, detecting the gene expression prog-1) have simple rounded shapes characteristic of stem cells that are still undecided what type of cell to become. In order to move these cells mist form extensions that reach out into the surrounding tissue and then the rest of the cell follows along, allowing them to move.
