Repairing and Analgesic Effects of Umbilical Cord Mesenchymal Stem Cell Transplantation in Mice with Spinal Cord Injury

Figure 5

GFP and GFAP expression in the spinal cord tissue of each group. In the frozen sections of the spinal cord tissue, DAPI was used to stain the nucleus, and the expression of GFP and GFAP in the tissue of the model and treatment groups was detected by fluorescence microscopy. While there was no GFP expression in the spinal cord of the model group, a small amount of GFP/GFAP immunofluorescence double-positive cells was shown in the treatment group. DAPI: 4,6-diamino-2-phenylindole; GFP: green fluorescent protein; GFAP: glial fibrillary acidic protein. Scale bars: 100 μm.
