摘要
A contusive model of spinal cord injury at spinal segment T8-9 was established in rats. Huantiao （GB30） and Huatuojiaji （Ex-B05） were punctured with needles, and endogenous neural stem cells were labeled with 5-bromo-2＇-deoxyuridine （BrdU） and NG2. Double immunofluorescence staining showed that electroacupuncture markedly increased the numbers of BrdU＋/NG2＋cells at spinal cord tissue 15 mm away from the injury center in the rostral and caudal directions. The results suggest that electroacupuncture promotes the proliferation of endogenous neural stem cells and oligodendrocytes in rats with spinal cord injury.
