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.

In this study, our main interest was to demonstrate the high level of neurobiological development of the Onychophora, as shown by the presence of cephalic ganglion, well-differentiated neurons characterized by a high production of synaptic vesicles, and having a proportionality of their cytoplasm and nucleus very much similar to that of planarian neurons (Reuter 1981, Biserova et al.
Because 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.

Chop a planarian into two pieces and each piece will develop the missing parts and become a separate planarian; the bead of one (or the left side) is identical to the corresponding part of the original; the tail of the other (or the right side) is identical to the tall of the original.
