Molecular Characterization of Spinal Tissue

September 15, 2025 updated by: A. Noelle Larson, MD, Mayo Clinic
The researchers are trying to identify molecular mechanisms that control spine deformity and degenerative changes that can be used for therapeutic strategies.

Detailed Description

Discarded surgical material from spinal procedures is collected. RNA analysis and other tests on the tissue is performed to determine markers of pathologic disease and to develop pharmacologic treatment strategies for pediatric spinal disorders.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Spine patients
Patients undergoing spine surgery where spinal tissue is discarded/removed will be recruited. Tissue samples will be used to look at normal and pathologic molecular signatures.
Other: Waste tissues are collected at the time of spinal surgery.
This is a single visit study. Waste tissues are collected at the time of spinal surgery.
