To regenerate a head, you first have to know where your tail is Planaria can't replace a missing head until after the tail develops sufficiently.

Understanding this regeneration in planarians is important for understanding this process in other organisms, since the molecular mechanisms that allow the correct regeneration of organs and ...

Next, Fan wanted to know if it was possible to “rescue” the regeneration process, and tested this by removing the planarian’s tail, too, which alerts the tail tissue that there is an injury.

Biologists are keen to understand how a type of flatworm known as a planarian uses powerful stem cells to regenerate an entire body from a headless sliver of itself.

Planarians, or flatworms that live in salt or freshwater, regenerate like crazy, Sánchez Alvarado said. There are about 8,000 species, so they had to choose one.

With an eye to understanding animal regeneration, Alejandro Sánchez Alvarado has turned a freshwater planarian into a model system to watch.

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 ...

Regeneration of tissues and organs is one of the great unsolved mysteries of biology. Whitehead Member Peter W. Reddien works to shed light on that mystery through research on the planarian Schmidtea ...

The Tufts researchers tested the memory of planarians, simple flatworms that are renowned for their regenerative properties. These worms can be cut up into pieces, and then each piece will grow ...
