Neural stem cell transplantation for treatment of cerebral palsy / 中国组织工程研究

ABSTRACT

BACKGROUND:Transplanted neural stem cel s can survive, proliferate and differentiate into neurons and/or glial cel s in the host, thereby promoting partial function recovery in the host. OBJECTIVE:To study the therapeutic effects of neural stem cel transplantation on cerebral palsy rats. METHODS:Twenty-four rats were randomly divided into three groupscontrol group, model group and transplantation group. Animal models of cerebral palsy were made in the latter two groups. One week after modeling, rats in the transplantation group were injected 1 mL stem cel suspension (1×105) via the jugular vein, and rats in the control and model group were given the same volume of normal saline. Toe distance, step length and elevated body swing test in rats were detected, and histopathological changes in the rat brain were observed 3 weeks after transplantation. RESULTS AND CONCLUSION:In the model group, the toe distance and step length of the front left palm were significantly lower than those of the front right palm (P body, but rats in the other two groups exhibited symmetric swing of the body (P<0.05). Additional y, the ratio of right to left hemispheric areas was significantly higher in the transplantation and control groups compared with the model group (P<0.05). In conclusion, neural stem cel transplantation via the jugular vein can improve brain function and restore motor function in rats with cerebral palsy.
