Fluoroscopic images demonstrating newly expressed neural stem/progenitor cells (co-expression of BrdU and Nestin). A : Sham group (Immunofluorescence, ×20). B : SCI-vehicle group (Immunofluorescence, ×20). C : SCI-curcumin group (Immunofluorescence, ×20). D : The bar graph reveals the quantification of cells positive for both BrdU and nestin in the spinal cord. Values in the histogram represent the means±standard deviation. *p<0.05, compared with the respective sham control. ^†p<0.05, compared with the respective vehicle control. Bars=50 μm. BrdU : Bromodeoxyuridine, SCI : spinal cord injury.
