One of the champions of nature. The new worm can grow up healthy, even from smaller pieces, cut off from the adult.
Forcing the "silent" gene named smedwi-2, biologists have deprived these worms the ability to regenerate. Moreover, the worms die not only for partitioning, but also on damage and dangerous diseases.
As it turned out, the work of this gene provides the possibility of regeneration, was responsible for the correct operation of stem cells, which supply a worm and just acts as a "patch" that require regeneration.
When you turn off smedwi-2 stem cells did not respond to tissue damage, and if as a result of stem cell division progeny appeared - it was not able to migrate to the right body parts. Moreover - the daughter cells "knew" how to differentiate.
In other words, in this gene have been statements that stem cells performed immediately at the time when it was time to heal the wound. This work may be important for medicine, because genes that resemble smedwi-2, found in humans.
