Obesity occurs when an excessive dietary fat intake leads to expansion of adipose tissue, which mainly consists of adipocytes that arise from proliferating and differentiating adipose stem cells, the preadipocytes. Obesity is a consequence of both adipocyte hypertrophy and hyperplasia. Knowledge about preadipocyte differentiation is relatively well established, whereas the mechanism responsible...
BACKGROUND Brown adipocytes are specialised in dissipating energy through adaptive thermogenesis, whereas white adipocytes are specialised in energy storage. These essentially opposite functions are possible for two reasons relating to mitochondria, namely expression of uncoupling protein 1 (UCP1) and a remarkably higher mitochondrial abundance in brown adipocytes. METHODOLOGY/PRINCIPAL FINDI...
The aim of this study was to evaluate a new approach for adipose tissue regeneration based on the utilization of human adipose tissue-derived mesenchymal stem cells (ASC) and biodegradable hydrogels as supporting matrix. Adipose tissue provides large stem cell numbers and tissue harvesting can be performed minimally invasive. ASC exhibit multilineage differentiation potential (e.g. osteogenic a...
This study is the first documentation of the isolation and extensive characterization of mesenchymal stem cells from canine adipose tissue. Methods previously used by our group to isolate and differentiate human adipose-derived mesenchymal stem cells (hAD-MSCs) have been modified and optimized for derivation of similar cells from canine adipose tissues. The canine adipose tissue-derived mesench...
Cell number is an important determinant of adipose tissue mass, and the coordinated proliferation and differentiation of preadipocytes into mature lipid-laden adipocytes underpins the increased adipose tissue mass associated with obesity. Despite this, the molecular cues governing such adipose tissue expansion are poorly understood. We previously reported that fibroblast growth factor-1 (FGF-1)...
BACKGROUND The total body adipose tissue volume is regulated by hormonal, nutritional, paracrine, neuronal and genetic control signals, as well as components of cell-cell or cell-matrix interactions. There are no known locally acting homeostatic mechanisms by which growing adipose tissue might adapt its volume. PRESENTATION OF THE HYPOTHESIS Mechanosensitivity has been demonstrated by mesench...
