Neural stem cells which can be provided stably and which are free from the problem of compatibility in transplantation are disclosed. The stem cells are separated from human amniotic mesenchymal cell layer and express vimentin, nestin and BrdU which are markers of neural stem cells. The stem cells can also ix differentiated to cells expressing alkaline phosphatase, that is, osteocytcs, and to cells expressing collagen type II, that is, chondrocytes. |
