Oxidation is believed to play a role in atherosclerosis. Oxidized lipids, sterols and proteins have been detected in early, intermediate and advanced human lesions at elevated levels. The spectrum of oxidized side-chain products detected on proteins from homogenates of advanced human lesions has been interpreted in terms of the occurrence of two oxidative(More)
Adult mesenchymal stem cells secrete a variety of angiogenic cytokines and growth factors, so we proposed that these paracrine mechanisms may be used to promote vascularization and growth for tissue engineering in vivo. We tested whether or not human adipose-derived stem cells (ASCs) promote tissue formation in rats. ASCs were evaluated in vitro for mRNA(More)
BACKGROUND/AIMS Biological and synthetic scaffolds play important roles in tissue engineering and are being developed towards human clinical applications. Based on previous work from our laboratory, we propose that extracellular matrices from skeletal muscle could be developed for adipose tissue engineering. METHODS Extracellular matrices (Myogels)(More)
The interaction of extracellular matrix with cells regulates their adhesion, migration and proliferation, and it is believed that damage to vascular matrix components is a factor in the development of atherosclerosis. Evidence has been provided for a role for the haem enzyme MPO (myeloperoxidase), released by activated monocytes (and possibly macrophages),(More)
Previous studies have provided compelling evidence for the presence of oxidized proteins and lipids in advanced human atherosclerotic lesions. The catalyst responsible for such oxidation is unknown and controversial. We have previously provided evidence for elevated levels of iron in lesions. In this study we hypothesized that if iron ions catalyzed protein(More)
Proteins associated with poly-beta-hydroxybutyrate (PHB) granules were purified from four Acinetobacter strains isolated from modified activated sludge treatment plants. Four predominant proteins of 64 kDa, 41 kDa, 38 kDa and 13 kDa were identified. N-terminal amino acid sequencing of the 64-kDa and 13-kDa proteins from Acinetobacter RA3849 identified these(More)
The ability to generate controlled amounts of adipose tissue would greatly ease the burden on hospitals for reconstructive surgery. We have previously shown that a tissue engineering chamber containing a vascular pedicle was capable of forming new fat; however, further refinements are required to enhance fat formation. The development and maintenance of(More)
