  1. ASCs had the greatest effect on M1 macrophages on day 5. Gene expression of inflammation-, degradation-, matrix production-, and tendon differentiation-related factors after one day (top) and five days (bottom) of co-culture with macrophages (M0, M1) or tri-culture with macrophages and ASCs (M0 + ASC, M1 + ASC). Data from each group were normalized first to untreated TFs and then to their paired control (that is, (M0 + ASC)/M0, (M1 + ASC)/M1). Data are presented as mean ± SD; N = 5 for day 1, N = 2 to 3 for day 5. This data is presented graphically in the supplemental document, Additional file 1: Figure S6. ASCs, adipose-derived mesenchymal stromal cells; biglycan; COL, collagen; COX, cyclooxygenase; DCN, decorin; IL-1β, interleukin-1β; MMP, matrix metalloproteinase; SCX, scleraxis; TFs, tendon fibroblasts; TNF, tumor necrosis factor; TNMD, tenomodulin.
