Abstract (original English)

To compare the phenotype and adipogenic and osteogenic differentiation capacities of adipose-derived mesenchymal stem cells (AMSCs) isolated from patients with psoriasis vulgaris and healthy donors, and to explore the effects of astragaloside IV, a Traditional Chinese Medicine, on the immunoregulatory function of AMSCs. AMSCs were isolated from human adipose tissue and cultured for three generations in vitro. Cell phenotype and cell cycle analysis were performed by flow cytometry. Adipogenic and osteogenic differentiation of AMSCs was examined by lipid (oil red O) and alkaline phosphatase staining, respectively. Expression of inflammatory mediators was examined by real-time quantitative polymerase chain reaction analysis, and proliferation was quantified using the cell counting kit-8 assay. Expression of CD29, CD44, and CD73 was higher in AMSCs from healthy donors than psoriasis patients, while the reverse was true for expression of CD45, CD31, and HLA-DR. AMSCs from psoriasis patients had a greater ability to undergo adipogenic differentiation than cells from healthy donors, whereas there was no significant difference in osteogenic differentiation between AMSCs from the two sources. Compared with AMSCs from healthy donors, psoriasis patient-derived AMSCs expressed lower levels of the anti-inflammatory cytokines interleukin-10 and trans-forming growth factor-β (TGF-β) and the i
