How support cells (interstitial fibroblasts) may cause prostate overgrowth

Interstitial fibroblasts drive prostate branching morphogenesis

NIH-funded research Ut Southwestern Medical Center · NIH-11320704

This project looks at whether support cells called interstitial fibroblasts cause prostate tissue to grow and form the nodules seen in benign prostatic hyperplasia (BPH) in adult men.

What this research studies

Researchers will map which signaling molecules these fibroblasts produce in developing human prostates and in BPH tissue using advanced spatial transcriptomics. They will test those signals on adult prostate epithelial cells and lab-grown prostate tissue to see if the signals drive cell growth and branching. The team will also use live models to study how fibroblast-derived signals control prostate epithelial behavior over time. Together these steps aim to trace how embryonic-like signaling might be reactivated in BPH.

Who could benefit from this research

Good fit: Men with benign prostatic hyperplasia or men undergoing prostate surgery who can donate tissue samples would be the most relevant participants.

Not a fit: People without a prostate or men without prostate enlargement seeking immediate symptom relief are unlikely to benefit directly from this research.

Why it matters

Potential benefit: If successful, the work could reveal specific signals that drive prostate enlargement and point to new targets to prevent or shrink BPH nodules.

How similar studies have performed: Cell-mapping and ex vivo organ experiments have helped uncover growth signals in other organs and the team's preliminary data suggest this approach can reveal new drivers of BPH, though applying it to adult prostate branching is a novel step.
