How bladder support cells control the lining and bladder pain

Official title: Signal integration by specialized mesenchyme in urothelial homeostasis and Interstitial Cystitis / Bladder Pain Syndrome

Funded at Stanford University · NIH-11378890 · Data updated 2026-11-12

Researchers are exploring whether special support cells in the bladder control nerve overgrowth and damage to the bladder lining in people with interstitial cystitis/bladder pain syndrome (IC/BPS).

Who could benefit from this research

Could help

People diagnosed with interstitial cystitis/bladder pain syndrome (IC/BPS), especially those with frequent flare-ups or Hunner’s lesions, would be the most relevant candidates.

Less likely to help

People whose pelvic pain comes from non-bladder causes or who do not have IC/BPS-related urothelial or nerve changes may not benefit from these findings.

What this research studies

The team uses mouse models and single-cell RNA sequencing to identify a specific group of bladder mesenchyme (support) cells that help regulate both nerve supply and the protective urothelial lining. They will study the signals these cells send and how those signals affect nerve growth and the bladder barrier. The work connects these cell behaviors to features of IC/BPS such as increased sensitivity, frequent flare-ups, and the severe loss of the urothelial barrier seen in cases with Hunner’s lesions. Findings are intended to point toward ways to prevent nerve overgrowth or restore the bladder lining.

Why it matters

Potential benefit: If successful, this work could point to new treatments that reduce bladder pain and urgency by preventing nerve overgrowth or repairing the bladder lining.

How similar studies have gone: Single-cell and mouse studies have successfully identified key cell types and signals in other organs, but applying this cell-type and signaling approach specifically to IC/BPS is relatively new.
