Resumo:
Obesity affects the functional capability of adipose-derived stem cells (ASCs) and their effective use in regenerative medicine through mechanisms still poorly understood. Here we employed a multiplatform (LC/MS, CE/MS, GC/MS) metabolomics untargeted approach to investigate the metabolic alteration underlying the inequalities observed in obese-derived ASCs. The metabolic fingerprint (metabolites within the cells) and footprint (metabolites secreted in the culture medium) from humans or mice, obese and non-obese derived ASCs, were characterized by providing valuable information. Metabolites associated to glycolysis, TCA, pentose phosphate pathway and polyol pathway were increased in the footprint of obese-derived human ASCs indicating alterations in the carbohydrate metabolism; whereas from the murine model, deep differences in lipid and amino acid catabolism were highlighted. Therefore, new insights on the ASCs metabolome were provided that enhance our understanding of the processes underlying the ASCs stemness capacity and its relationship with obesity, in different cell models.
