Functional Properties of Suburothelial Microvessels in the Rat Urinary Bladder

• Supplementary video 1
  Spontaneous constrictions of a suburothelial venule. An arteriole (above) did not develop spontaneous constrictions.
• Supplementary video 2
  Spontaneous Ca²⁺ transients in smooth muscle cells of a suburothelial venule. Smooth muscle cells in an arteriole (below) did not exhibit spontaneous Ca²⁺ transients.
• Supplementary video 3
  Spontaneous Ca²⁺ transients in perivascular ICs network of a suburothelial venule.
• Supplementary video 4
  Spontaneous Ca²⁺ transients in perivascular ICs network of a suburothelial venule that had been treated with wortmannin (1 μM) to minimize movement artifacts.
• Supplementary video 5
  Asynchronous spontaneous Ca²⁺ transients in perivascular ICs of a suburothelial venule that had been treated with nicardipine (1 μM).
