5-HT regeneration correlates to LUT function recovery.

<p>Pearson correlation coefficient (<i>r</i> value) comparing bladder recovery to the number of regenerating (A-D) 5-HT and (E-H) TH fibers found in the caudal cord 200μm or 500μm from the PNG-cord interface. The number of regenerated 5-HT fibers below the lesion site shows a significant correlation with the improvement of CMG parameters. There is no significant correlation between regeneration of the TH fibers and CMG parameter analysis. Only animals whose spinal cord was processed and cut sagittally were included in the analysis. n = 7.
