EGFR is a pivotal regulator of thrombin-mediated inflammation in primary human nucleus pulposus culture

Abstract We found that the coagulation and cytokine pathways were important mechanisms involve in the degeneration of intervertebral discs (IVD) using a microarray approach to analyze gene expression in different grades of specimens. Furthermore, using a cytokine/chemokine array, a significant incre...
