Even amongst planarian
flatworms, famous for their ability to regenerate from random tissue fragments, species exist that have completely lost the ability to regenerate.
The study, entitled "zic-1 Expression in Planarian
Neoblasts after Injury Controls Anterior Pole Regeneration," was reported in PLOS Genetics.
Jacob, who also won a full four-year scholarship to the University of Massachusetts at Boston, studied the eyespots of planarian
(freshwater flatworms) before and after regeneration for his project, Getting NERVEous.
Scientists at the park are monitoring the pink planarian
The ability to follow individual neoblasts opens the door to uncovering the molecular cues that help planarian
stem cells navigate to the site of injury and ultimately may allow scientists to provide therapeutic stem cells with guideposts to their correct destination.
The team, from the University of Nottingham's School of Biology, is studying two types of planarian
flatworms that can regenerate muscles, skin, guts and brains through a unique process of cell division.
Levin's group has taken the observation to a new level and has shown that manipulating electrical properties of cells can produce strange results, such as this four-headed planarian
Contributors are actively involved with the development and use of planarian
stem cells share characteristics with those of humans, the work will aid scientists to understand how stem cells can completely repair damaged tissues and organs.

The first known Texas population of the land planarian
Geoplana arkalabamensis Ogren and Darlington, 1991, is reported.
A pluralistic version of utilitarianism may also justify the intuition that, other things being equal, it is better to use a planarian
than a mouse, and better to use a rat than a chimpanzee.
