Abstract (original English)

Osteoporosis is characterized by osteopenia and bone tissue microstructure degradation. Adipose-derived stem cells (ADSCs) are multipotent adult stem cells that have the ability to yield mesenchymal stem cells and have the potential to undergo osteogenesis and bone regeneration. Therefore, ADSCs have the potential to treat osteoporosis, but the molecular mechanism of these cells in the process of osteogenesis and osteoclasts is still not clear. In the present study, we collected serum samples from 10 clinical osteoporosis patients to detect long noncoding RNA-neighboring enhancer of FOXA2 (lncRNA-NEF) and miR-155 expression levels. Half of these patients were senile and half were postmenopausal women, and nine of them have used steroids for a long time, in which ADSCs were cultured and induced to adipogenic and osteogenic differentiations. Quantitative real-time polymerase chain reaction was used to detect the expression of genes in ADSCs. Overexpression of lncRNA-NEF in ADSCs were undertaken to verify its regulatory function on cell osteogenic and adipogenic differentiations. A luciferase activity experiment was performed to determine the relationship between miR-155 and phosphatase and tensin homologue deleted on chromosome 10 (PTEN). The level of lncRNA-NEF was downregulated, and miR-155 was upregulated, in serum samples from patients with clinical osteoporosis. LncRNA-NEF s
