Fig. 4From: Characterizing heterogeneity in the response of synovial mesenchymal progenitor cells to synovial macrophages in normal individuals and patients with osteoarthritisDendrogram clustering analysis of cytokines and chemokines secreted from synovial explants. Dendrogram analysis of the inflammatory secretome from normal and OA biopsies after cytokine stimulation with or without clodronate treatment demonstrated that all normal biopsies grouped together under all treatment groups, while OA samples clustered on the presence/absence of clodronateBack to article page
