Scientists have struggled with the mystery of why stem cells can't generate neurons in a lab dish, but Duke University Medical Center researchers believe that a network of cells surrounding stem cells in the brain, called ependymal cells, is what allows stem cells to continue making new neurons.
When neural stem cells are harvested for growth in culture, however, the ependymal cells are not removed along with them, and this can be a problem.
The scientists found that neighbouring "epithelial-like" ependymal cells - not stem cells themselves - maintain a special structure that keeps neural stem cells "neurogenic," able to make new neurons.
