A gut feeling about neural stem cells
Proper function of the digestive system requires coordinated contraction of the muscle in the wall of the intestinal tract, regulated by the enteric nervous system. Damage or loss of these neurons can result in intestinal motility disorders, such as Hirschsprung's disease, for which there is a dearth of effective treatments. In principle, disorders of the enteric nervous system could be treated by cell therapy, but it was previously unknown whether transplanted stem cells could migrate to the appropriate location in the gut and then become neurons that could properly innervate the bowel. In this issue of the Journal of Clinical Investigation, Heather Young and colleagues at the University of Melbourne, isolated neural stem cells from mice, cultured them to promote the formation of neural precursor cells, and implanted them into the muscle in the colons of recipient mice. Young and colleagues found that these cells were able to migrate away from the transplantation site and develop into neurons that provided stimulation to the portions of the gut the regulate motility. These findings suggest that the transplantation of neural stem cells is a promising therapeutic avenue for the treatment of gastrointestinal motility disorders.

A cellular adhesion protein protects against inflammation
Cellular inflammation is mediated by a group of proteins known as the inflammasome. In this issue of the Journal of Clinical Investigation, Ziad Mallat and colleagues at Addenbrooke's Hospital in Cambridge, England, identified a protein, MFGE8, that blocks inflammasome activity. Using a mouse model of stroke, Mallat and colleagues determined that expression of MFGE8 inhibited the production of pro-inflammatory products and limited the area of injury after stroke. These results identify MFGE8 as an important regulator of inflammation that could potentially serve as a useful therapeutic target in inflammatory disease.
