Abstract (original English)

Background and objectives Adipose tissue is a source of mesenchymal stem cells, which have the potential to differentiate into various types of cells. Adipose-derived stem cells (ADSCs) are now recognized as an accessible, abundant, and reliable stem cells suitable for tissue engineering and regenerative medicine applications. However, few literatures gave a comprehensive report on the capacities of ADSCs harvested from different sites. Especially, the capacities of ADSCs from aged mice remained unclear. In this study, we investigated several main capacities of brown adipose derived stem cells (B-ADSCs) and white adipose derived stem cells (W-ADSCs) from both young and aged mice. Methods and results When isolated from young mice, B-ADSCs showed a stronger proliferation rate and higher osteogenic, adipogenic and myocardial differentiation ability than W-ADSCs. Carboxy fluorescein diacetate succinimidyl ester (CFSE) labeling test suggested no significant difference in immunosuppression capacity between B-ADSCs and W-ADSCs. Similarly, no difference between these two were found in several immune related molecules, such as programmed death-ligand 1 (PD-L1), intercellular cell adhesion molecule (ICAM-1), vascular cell adhesion molecule (VCAM-1), inducible nitric oxide synthase (iNOS), tumour necrosis factor- α (TNF- α ), interleukin 10 (IL10), and suppressor of cytokine signaling 1 (
