Abstract: A method for screening materials with neuronal regeneration effect using a tissue fragment of the spinal cord is provided to be usefully used to develop a therapeutic agent of neuronal diseases. A method for screening neuronal regeneration materials comprises the steps of: (a) culturing a tissue fragment obtained from the spinal cord; (b) treating the tissue fragment under the culturing with a toxic compound to damage the tissue fragment; (c) treating the damaged tissue fragment with a candidate material expected to have the neuronal regeneration effect; and (d) screening the candidate material showing significant neuronal regeneration effect by comparing the result with a negative control group not-treated with the candidate material, wherein the candidate material is a compound, a growth factor, cytokine, a mesenchymal stem cell derived factor, an extracellular matrix protein, a protein involved with growth of axon, or a factor involved with intracellular signal transduction and the toxic compound is lysolecithin inducing demyelination of the axon of the spinal cord. Further, the damage is demyelination.

Abstract: A method for inducing differentiation of mesenchymal stem cells using pre-inductions and neuronal induction media(NIM) supplemented with butylated hydroxyanisole, forskolin and VPA is provided to differentiate the mesenchymal stem cells into neurons or motor neurons effectively, thereby being used as a cell therapeutic agent of neurodegenerative diseases. A method for inducing differentiation of mesenchymal stem cells into neurons comprises the steps of: (a) performing pre-induction of mesenchymal stem cells twice; and (b) inducing differentiation of the pre-differentiated mesenchymal stem cells of the step(a) in a neuronal induction medium containing butylated hydroxyanisole(BHA), forskolin and valproic acid (VPA) for 2-8 hours, wherein the content of beta-mercaptoethanol added for the second pre-induction is increased 1.5-2 times from the content added for the first pre-induction. The second pre-induction time is reduced to 1/4-1/8 of the first pre-induction time and the neuronal induction medium contains 100-200 muM of BHA, 9-11 muM of forskolin and 1.5-2.5 muM of VPA.
