Planaria are freshwater flatworms that have become a key model for studying regeneration and stem cells, as they can regenerate any part of the body, even the head. But how does the animal know what ...

For those of us whose memory of high school biology hasn't faded entirely, planarians will probably sound very familiar. They're generally used as an example of one of the extreme ends of regenerative ...

Nelson Hall wants you to know that the googly-eyed flatworm he just sliced into four pieces is going to be OK. In fact, it's going to be great. Three of the flatworm's four pieces have started to ...

A mouse injured on one leg experiences an “awakening” of stem cells in the other leg as if the cells are preparing to heal an injury. Something similar happens in axolotls, which are masters at limb ...

Researchers at the University of Utah are among the first to use large-scale genetics to study the planarian Schmidtea mediterranea, which contains a genome thought to contain insight into adult stem ...

A West Virginia University biologist is studying why some animals can regenerate while others cannot and has identified the genes that play a role in the process. Christopher Arnold, assistant ...

Among their many extraordinary feats, some planarian flatworms reproduce by tearing off pieces of themselves to regenerate new worms. Now, researchers have discovered that this process is controlled ...
