Fig. 3From: Pirt contributes to uterine contraction-induced pain in miceSmall-diameter DRG neurons innervate the uterus. Bright-field (a) and fluorescence (b) imaging of Dil-labeled DRG. c Overlapping images from a and b permit differentiation between traced and untraced fibers. Scale bar 20 µm. d Most DRG neurons that received input from the uterus had a small soma size, with a surface area ranging from 100 to 600 μm2 (1599 labeled neurons in T13 DRG)Back to article page
