Deskripsi
<i>Context:</i> Adipose-derived mesenchymal stem cells (ADMSCs) are progenitor cells that shape the tissue’s biological properties. <i>Objective:</i> To examine the adipocytes differentiated from the ADMSCs of lean and obese individuals with/without a metabolic syndrome (MetSx) cytokine secretory profile, as to date, little is known on this topic. <i>Methods:</i> Interleukin, chemokine and growth factor levels in the culture medium were determined using the Human Cytokine kit. <i>Results</i>: We observed a characteristic secretory fingerprint displayed by the cells from the MetSx group and identified a set of putative markers (IL-1β, IL-6, IL-7, IL-10, IL-12, IL-13, VEGF, FGF, GM-CSF, TNF-α, IFN-γ) of the condition. Surprisingly, the concentrations of most of the molecules (except for IL-6, IFN-γ, IP-10, VEGF) decreased when compared with the cells from the lean group. We postulate that the difference stemmed from the fact that in vivo cytokines were mostly secreted by the activated monocytes/macrophages and not adipocytes per se. This may also suggest that the aforementioned upregulated cytokines (IL-6, IFN-γ, IP-10, VEGF) might have been the ones that attracted monocytes and triggered the vicious cycle of tissue inflammation. <i>Conclusions</i>: Our study indicated that the adipocytes newly derived from the ADMSCs of obese patients with metabolic syndrome displayed a secretory fingerprint that may be characteristic to the early stages of the condition.
