Research has found that a molecule gives the stem cells of the worm, known as a planarian, regenerative power. A planarian can grow an entire new worm from a tiny piece of any part of its body except for the pharynx (a digestive organ) and the region in front of its light-sensing eye spots.</p> St. Louis Post-Dispatch via Philadelphia Inquirer https://freerepublic.com/focus/f-news/1683195/posts#comment Mon, 14 Aug 2006 04:33:58 GMT
