Results Trunk neural crest stem cells were successfully isolated and cultured. The immuocytochemcal result showed that the cells were nestin-and P75-positive. Trunk neural crest stem cells grew through adhering to chitosan fiber after inoculation. Under an electon microscope, the spindle-shaped trunk neural crest stem cells were proliferated and migrated along the fiber.
