Depending on the inflammatory milieu, injury can result either in a tissue's complete regeneration or in its degeneration and fibrosis, the latter of which could potentially lead to permanent organ failure. Yet how inflammatory cells regulate matrix-producing cells involved in the reparative process is unknown. Here we show that in acutely damaged skeletal(More)
The absorption, disposition, metabolism and excretion study of orally administered 2,2',4,4',6-pentabromodiphenyl ether (BDE-100) was studied in conventional and bile-duct cannulated male rats. In conventional rats, >70% of the radiolabelled oral dose was retained at 72 h, and lipophilic tissues were the preferred sites for disposition, i.e. adipose tissue,(More)
Fourier Transform spectroscopy is beginning to flourish. However, unlike the almost explosive growth following a discovery in some fields, such as gas chromatography or lasers, the use of scanning interferometer systems to measure spectra has had to pass through a long period of quiescence. The latter was, essentially, enforced through the lack of(More)
Fibro/adipogenic progenitors (FAPs ) are tissue-resident mesenchymal stromal cells (MSCs). Current literature supports a role for these cells in the homeostasis and repair of multiple tissues suggesting that FAPs may have extensive therapeutic potential in the treatment of numerous diseases. In this context, it is crucial to establish efficient and(More)
The effects of 1-O-hexadecyl-2-O-methyl-sn-glycero-3-phosphocholine (ET-16-OCH3-GPC) and its metabolite 1-O-hexadecyl-2-O-methyl-sn-glycerol (AMG) on the activity of diacylglycerol kinase (DGK) in WEHI-3B cells were investigated. Treatment of WEHI-3B cells with 200 nM 12-O-tetradecanoylphorbol-13-acetate (TPA) for 5 min leads to the activation of cytosolic(More)
Acute skeletal muscle injury triggers an expansion of fibro/adipogenic progenitors (FAPs) and a transient stage of fibrogenesis characterized by extracellular matrix deposition. While the perpetuation of such phase can lead to permanent tissue scarring, the consequences of its suppression remain to be studied. Using a model of acute muscle damage we were(More)
Fibro/Adipogenic Progenitors (FAPs) are a multipotent progenitor population resident in skeletal muscle. During development and regeneration, FAPs provide trophic support to myogenic progenitors that is required for muscle fiber maturation and specification. FAPs also represent a major cellular source of fibrosis in degenerative disease states, highlighting(More)
