What this research studies
This project will build high-resolution 3-D anatomical models of knee nerves using tissue-clearing, ribbon-scanning confocal, and lightsheet imaging on mouse and human samples. The team will label different nerve types and apply single-cell and spatial transcriptomics to create a cell atlas showing gene activity in knee-innervating neurons. They will compare nerves from young, aged, injured, and osteoarthritic knees to document how patterns and molecular signals change. The maps and interactome data aim to reveal nerve–joint connections that could guide new pain-relief strategies.
Who could benefit from this research
Good fit: Ideal participants are people with knee osteoarthritis or patients undergoing knee surgery who can donate tissue or allow their tissue to be studied.
Not a fit: People without knee problems or those not able or willing to donate tissue are unlikely to get direct benefit from participating.
Why it matters
Potential benefit: If successful, this work could reveal specific nerve cell targets or pathways that lead to better treatments for knee pain and osteoarthritis.
How similar studies have performed: High-resolution imaging and single-cell profiling have helped identify pain-related nerve types in other tissues, but a comprehensive 3-D nerve atlas specific to the knee is largely new.
