ligamentum flavum (LF), which leads to lumbar spinal stenosis (LSS). The fibroblast growth
factor (FGF) family is a key mediator of fibrosis. However, acidic fibroblast growth factor (FGF-
1) expression and function are not well understood in LF. This study sought to evaluate FGF-
1 expression in the hypertrophied and non-hypertrophied human LF, and to investigate its
function using primary human LF cell cultures. Methods We obtained hypertrophied lumbar …
