Abstract
We developed a new model for evaluation of the influence of proinflammatory cytokines on intervertebral disc cells in a 3D culture based on co-culturing of these cells with activated macrophage-like THP-1 cells. The levels of TNFα, IL-1β, IL-6, IL-8, IL-10, and IL-12p70 production were assessed by flow cytofluorometry using microspheres. Considerable differences in the level of spontaneous cytokine secretion by normal and degenerated intervertebral disc cells were revealed. A significant increase in the level of IL-1β and IL-8 was observed during co-culturing, which confirms consistency of the developed model.
