In recent years, research in the areas of stem cells has dramatically increased, including studies of cellular adhesion to a substrate. We sought to determine the adhesive properties of human adipose-derived stem cells (hASCs) for extracellular matrix proteins. The adhesion of hASCs to collagens and laminin was completely inhibited by a monoclonal antibody,(More)
We investigated whether transplantation of three-dimensional cell masses (3DCM) of human adipose-derived stromal cells (hASCs) cultured on a basic fibroblast growth factor-immobilized substrate improved hind limb functional recovery by stimulating angiogenesis in an immune-competent rat ischemic limb model. In vitro experiments confirmed that cells within(More)
The aim of this study was to investigate the effects of low-level laser therapy (LLLT) on transplanted human adipose-derived mesenchymal stem cells (hASCs) spheroid in a hind limb ischemia animal model. LLLT, hASCs spheroid and hASCs spheroid transplantation with LLLT (spheroid + LLLT) were applied to the ischemic hind limbs in athymic mice. The survival,(More)
We investigated whether low-level light irradiation prior to transplantation of adipose-derived stromal cell (ASC) spheroids in an animal skin wound model stimulated angiogenesis and tissue regeneration to improve functional recovery of skin tissue. The spheroid, composed of hASCs, was irradiated with low-level light and expressed angiogenic factors,(More)
PURPOSE We examined whether fractional exhaled nitric oxide (FeNO) levels are associated with atopy profiles in terms of mono-sensitization and poly-sensitization in asthmatic children. METHODS A total of 119 children underwent an assessment that included FeNO measurements, spirometry, methacholine challenge, and measurement of blood eosinophil count,(More)
In this paper, we investigated alginate microspheres as a low-cost adsorbent for strontium (Sr(II)) removal and recovery from seawater. Alginate microspheres have demonstrated a superior adsorption capacity for Sr(II) ions (≈110 mg/g). A Freundlich isotherm model fits well with the Sr(II) adsorption of an alginate microsphere. The mechanism of Sr(II)(More)
Moving picture experts group (MPEG)-4 visual conformance standard specifies methods to verify whether bitstreams and decoders meet the requirements at a specified profile and level. The test of decoders can be divided into two parts: static and dynamic tests. The static test can be performed by comparing images from a decoder under test with those from a(More)
To investigate the tolerance factor of Saccharomyces cerevisiae KNU5377 against various types of environmental stress during fermentation, we identified the protein that is upregulated at high temperatures. The highly upregulated protein was high-score-matched as a cytoplasmic peptidyl-prolyl cis-trans isomerase, cyclophilin (Cpr1p), by matrix-assisted(More)
Human adipose-derived mesenchymal stem cells (hASCs) are attractive cell source for skin tissue engineering. The aim of this study was to investigate the effects of low-level light therapy (LLLT) on transplanted cluster hASC in a skin wound animal model. The hASCs were cultured in monolayer or clusters. The LLLT, hASCs, hASC clusters, and hASC clusters(More)
