Transforming growth factor-beta 1-mediated collagen gel contraction by cardiac fibroblasts.
OBJECTIVE Myofibroblasts and transforming growth factor-beta(1) (TGF-beta(1)) are key elements of cardiac tissue fibrosis development. The aim of this study was to determine whether the ability of TGF-beta(1) to affect the contractile activity of cardiac fibroblasts depends on their differentiation into myofibroblasts. METHODS Cardiac fibroblasts (from male adult Wistar rats) from passage two...
متن کاملTransforming growth factor-β1-mediated collagen gel contraction by cardiac fibroblasts
Results TGF-β1 dose-dependently increased the contraction of collagen gel mediated by cardiac fibroblasts, reaching a maximal effect at 100 pmol/L TGF-β1. TGF-β1 also stimulated H-thymidine incorporation and total protein content in cardiac fibroblasts in the collagen gel lattice. TGF-β1 dose-dependently induced an increase in αsmooth muscle actin, a marker of myofibroblasts. The TGF-β1-induced...
متن کاملStimulation of collagen production by transforming growth factor-beta1 during differentiation of cardiac fibroblasts to myofibroblasts.
The aim of the present study was to elucidate how transforming growth factor-beta(1) (TGF-beta(1)) can stimulate collagen deposition in cardiac tissue by interstitial cells via stimulation of fibroblasts, via myofibroblasts, or via differentiation of fibroblasts to myofibroblasts. The dose- and time-dependent stimulation of collagen production and of expression of alpha-smooth muscle actin (alp...
متن کاملTransforming growth factor-beta 1 promotes contraction of collagen gel by bovine corneal fibroblasts through differentiation of myofibroblasts.
PURPOSE To determine whether the ability of transforming growth factor-beta (TGF-beta) to influence the contractile activity of corneal fibroblasts depends on their differentiation into myofibroblasts. METHODS Bovine corneal fibroblasts were cultured on collagen gel in MED 5 medium (F-12 nutrient mixture supplemented with 5% fetal bovine serum) with or without TGF-beta 1 (0.01-10 ng/ml). To e...
متن کاملIntegrin-mediated collagen gel contraction by cardiac fibroblasts. Effects of angiotensin II.
Angiotensin II (Ang II), a vasoactive octapeptide, has been implicated in cardiac growth and the development of hypertrophy and fibrosis secondary in hypertensive disease. These consequences of Ang II imply an effect on the function and morphology of cardiac interstitial cells (fibroblasts). The present investigation was designed to (1) determine whether neonatal heart fibroblasts (NHFs) posses...
