[The study of primary culture methods for hippocampal neurons of newborn rats].

Aim: To compare three different methods for neuron culture, so as to provide a culture technique with higher neuron purity and survival rate.

Methods: Neurons in hippocampal region of newborn SD rats were cultured by common culture method, cytosine arabinoside (Ara-c)-supplementing method, Ara-c and nerve growth factor (NGF)-supplementing method. Then morphology of neurons was observed under microscope.
