Abstract
In order to provide a method for producing neural stem cells easily and quickly by inducing differentiation of somatic cells directly into neurospheres, dedifferentiation factors are introduced into somatic cells, which are then cultured in suspension in the presence of growth factors to produce the neurospheres, thereby allowing the neural stem cells to be produced quickly without establishing iPS cells.
