| Abstract: | Objective:To study the characteristics of isolation,culturing,multipotentiality and in-duced differentiation of neural stem cells derived from the spinal cord of embryonic rats.Methods:Serum free and clone culturing and im munocytochemistry were enlisted to observe the in vitro proliferation and differen tiation of the neu ral stem cells derived from the spinal cord and to identify differentiated neu ral cells.Results:The neural stem cells have the ability of proliferation and en dour passage.Nestin positive cells can be found in the daughter clones.In duced by10%serum,they can attach and differenti ate into MAP2,GFAP and GC positive cells.Conclusion:The neural stem cells the derived from the spinal cord of em bryonic rats have the ability of proliferation and multipotentiality. |
