- The purpose of this study was to investigate the anti-inflammatory effect of platelet-rich plasma (PRP) with collagen matrix on human nucleus pulposus (NP) cell in response to pro-inflammatory cytokines such as tumor necrosis factor-alpha (TNF-α) and interleukin-1 (IL-1). NP cells from human disks were cultured in a monolayer and maintained in the collagen matrix prior to the addition of recombinant human IL-1 and TNF-α. After applying IL-1 and TNF-α, PRP prepared by using a commercially available platelet concentration system was added. The response was investigated using real-time PCR for mRNA expression of type II collagen, aggrecan, matrix metalloproteinase-3 (MMP-3), and cyclooxygenase-2 (COX-2). The combination of IL-1β and TNF-α led to decrease of matrix synthesis gene expression such as collagen type II and aggrecan and increase of the degradation gene expression of COX-2 and MMP-3, compared to the control. Consecutive PRP exposure significantly recovered the down-regulated gene expression of collagen type II and aggrecan and significantly reduced the increased MMP-3 and COX-2 gene expression, compared to that of control groups with pro-inflammatory cytokines. The administration of PRP with collagen matrix markedly suppressed cytokine-induced pro-inflammatory degrading enzymes and mediators in the NP cell. It also rescued gene expression concerning matrix synthesis, thereby stabilizing NP cell differentiation.
