How developmental signals keep spinal discs healthy
Role of Developmental Signaling Pathways in Maintenance of Spinal Discs
This research looks at whether a developmental signal called sonic hedgehog (SHH) helps keep adult spinal discs healthy and prevents age-related disc breakdown.

What this research studies
The team will combine lab work in mice with analysis of human spinal disc tissue to learn how developmental signals maintain disc cells and structure. They will use genetic mouse models and lineage tracing to track cells that make the SHH signal, and organ culture experiments that mix young and old tissue to test repair potential. High-throughput gene expression techniques will identify which pathways change with age. Human disc samples will be analyzed to compare findings from mice to people.
Who could benefit from this research
Good fit: Adults with degenerative intervertebral disc disease or chronic low back pain, especially those having spine surgery or tissue donation, would be most relevant to this work.
Not a fit: People whose back pain is due to acute injury, nerve disorders unrelated to disc degeneration, or who need immediate pain relief may not directly benefit from this basic/translational research.
Why it matters
Potential benefit: If successful, this work could point to new ways to slow or reverse disc degeneration and reduce chronic back pain.
How similar studies have performed: Prior laboratory and animal studies indicate SHH influences disc cell behavior, but translating these findings into human treatments remains largely untested.
