The objective is to establish a model of spinal cord organotypic culture in vitroof Sprague Dawlay rat.

Study Design. An experimental study to investigate the in vitro gene expression of neurotrophic factors and receptors in cultured rat spinal cord cells subjected to cyclic mechanical stretch forces.

Aim: To observe the differentiation, immigration, and improvement of behavior after infusion human cord blood mononuclear cells (HCMNCs) in rat spinal cord injury model.
