Fig. 3From: Characterizing heterogeneity in the response of synovial mesenchymal progenitor cells to synovial macrophages in normal individuals and patients with osteoarthritisPrinciple component analysis of cytokines and chemokines secreted from synovial explants. Supernant from 8 OA and 4 normal biopsies was examined using the Luminex platform. Normal biopsies clustered together in all treatment groups (IFNγ, TNFα, IL-4 or IL-10), regardless of the presence or absence of clodronate. OA biopsies demonstrated no discernable pattern with the exception of IL-10 treatment in which all biopsies treated with or without clodronate clustered togetherBack to article page
