How flatworms regrow their eyes
Flatworms have uncanny regenerating abilities: they can regrow into a whole organism from a body piece as small as one-279th of the original size. Researchers now have shown that specialized cells hidden throughout the body act as guides for regeneration. When the flatworm Schmidtea mediterranea is growing new eyes, the cells help eye neurons to grow connections to the brain. Similar guidepost cells have an important role in embryo development in many animals, says biologist Peter Reddien, but are absent in typical adult organisms.
