Bladder-colon chronic cross-sensitization involves neuro-glial pathways in male mice

Figure 4 Number of microglia cells in the spinal cord. A and B: Microglial cells in the dorsal horn of the L6-S1 level of the spinal cord were stained green [green fluorescent protein on the fractalkine receptor-positive (CX3CR1^gfp+) mice], while nuclei appear in blue (DAPI) at day 7 after intravesical injections of saline (NaCl 0.9%) (A) or acetic acid 0.75% (B); C: The number of microglial cells per field was compared between the two groups using a Mann-Whitney bilateral test (n = 5 per group, average of 23 slices analyzed per mouse). ^aP < 0.05. Results are expressed as the mean ± standard error of the mean.
