Inflammatory Cytokines Induce Fibrosis and Ossification of Human Ligamentum Flavum Cells

Abstract

Inflammatory cytokines (IL-6, TNF-α, PGE2, and NO) seem to play a crucial role in hypertrophy and ossification of LF. Degenerated, herniated intervertebral disks, and facet arthrosis may influence LF through inflammatory cytokines and cause hypertrophy and ossification of LF.
