(A, B) Immunohistochemical analysis of neuron proliferation related proteins. Samples were incubated with antibodies to the neural stem cell proliferation related proteins BrdU and nestin and to Tuj1, Ng2+, and GFAP, which are markers for neurons, oligodendrocytes and astrocytes, respectively. rTMS and hUCB-MSCs transplantation promoted the proliferation of neuron stem cells, oligodendrocytes and astrocytes. * p<0.05 and ** p<0.01 compared with rats subjected to SCI alone; ^# p<0.05 compared with rTMS.
