To date, no adequate implant material for the correction of soft tissue defects such as after extensive deep burns, tumor resections or in congenital defects is available. A biohybrid composed of viable adipose precursor cells and an optimised matrix could help towards a solution. Morphologically, preadipocytes resemble fibroblasts and have not yet built a(More)
BACKGROUND Oxidative damage of vascular endothelium represents an important initiation step in the development of atherosclerosis. Recently, we reported about protection of inducible nitric oxide synthase (iNOS)-derived high-output NO in endothelial cells. Because iNOS activity critically depends on the availability of its substrate l-arginine, the present(More)
BACKGROUND There is a major clinical need for strategies for adequately reconstructing the soft tissue defects found after deep burns, tumor resection, or trauma. A promising solution is adipose tissue engineering with preadipocytes, stem-cell derived precursors of the adipose tissue, implanted within biomaterials. This pilot study evaluated hyaluronan gels(More)
In endothelial cells, the expression of the inducible nitric oxide synthase (iNOS) and the resulting high-output nitric oxide synthesis have often been assumed as detrimental to endothelial function, but recent publications have demonstrated a protective role resulting from iNOS espression and activity. To address this question, we used antisense-mediated(More)
