Popis: Human adipose mesenchymal stem cells are a heterogeneous population, where cell cultures derived from single cell-expanded clones present varying degrees of differential plasticity. This work focuses on the immunomodulatory/anti-inflammatory properties of these cells. To this end, 5 single cell clones were isolated (generally called 1.X and 3.X) from 2 volunteers. Regarding the expression level of the lineage-characteristic surface antigens, clones 1.10 and 1.22 expressed the lowest amounts, while clones 3.10 and 3.5 expressed more CD105 than the rest and clone 1.7 expressed higher amounts of CD73 and CD44. Regarding cytokine secretion, all clones were capable of spontaneously releasing high levels of IL-6 and low to moderate levels of IL-8. These differences can be explained in part by the distinct methylation profile exhibited by the clones. Furthermore and after lipopolysaccharide stimulation, clone 3.X produced the highest amounts of pro-inflammatory cytokines such as IL-1β, while clones 1.10 and 1.22 highly expressed IL-4 and IL-5. In co-culture experiments, clones 1.X are altogether more potent inhibitors than clones 3.X for proliferation of total, CD3+T, CD4+T and CD8+T lymphocytes and NK cells. The results of this work indicates that adipose stem cell population is heterogeneous in cytokine production profile, and that isolation, characterization and selection of the appropriate cell clone is a more exact method for the possible treatment of different patients or pathologies.
