Abstract (original English)
Inorganic polyphosphate [Poly(P)] induces differentiation of osteoblastic cells. In this study, matrix metalloproteinase (MMP)-13 small interfering RNA (siRNA) was transfected into human adipose tissue-derived mesenchymal stem cells (hAT-MSC) to investigate whether MMP-13 activity induced by Poly(P) is associated with osteogenic differentiation. Real-time quantitative polymerase chain reaction, Western blotting, and an MMP-13 activity assay were used in this study. Poly(P) enhanced expression of mature osteoblast markers, such as osteocalcin (BGLAP) and osteopontin (SPP1), osterix (OSX), and bone sialoprotein (BSP), and increased alkaline phosphatase (ALP) activity and calcification capacity in hAT-MSCs. These cells also developed an osteogenic phenotype with increased expression of Poly(P)-induced expression of MMP-13 mRNA and protein, and increased MMP-13 activity. MMP-13 siRNA potently suppressed the expression of osteogenic biomarkers BGLAP, SPP1, OSX, BSP, and ALP, and blocked osteogenic calcification. Taken together, Poly(P)-induced MMP-13 regulates differentiation of osteogenic cells from hAT-MSCs.
