To understand how these observations may relate to differences between mesenchymal stromal/stem cells from healthy subjects and subjects with fibrosis, we have characterized the fibrogenic and adipogenic potential of adipose-derived mesenchymal stromal/stem cells from systemic sclerosis patients, from mice with fibrotic lung and skin disease induced by systemic bleomycin treatment, and from healthy controls. Early passage systemic sclerosis adipose-derived mesenchymal stromal/stem cells have a profibrotic/anti-adipogenic phenotype compared to healthy adipose-derived mesenchymal stromal/stem cells (low caveolin-1, high ¦Á-smooth muscle actin, high HSP47, low pAKT, low capacity for adipogenic differentiation). This phenotype is mimicked by treating healthy adipose-derived mesenchymal stromal/stem cells with transforming growth factor beta or caveolin-1 small interfering RNA and is reversed in systemic sclerosis adipose-derived mesenchymal stromal/stem cells by treatment with caveolin-1 scaffolding domain peptide, but not scrambled caveolin-1 scaffolding domain peptide. Similar results were obtained with adipose-derived mesenchymal stromal/stem cells from systemic sclerosis patients and from bleomycin-treated mice, indicating the central role of caveolin-1 in mesenchymal stromal/stem cell differentiation in fibrotic disease %K Caveolin-1 %K fibrosis %K adipogenesis %K mesenchymal stem cells %K scleroderma %U https://journals.sagepub.com/doi/full/10.1177/2397198318821510
