چکیده

Methods. Bovine lens epithelial cells (BLECs) obtained from the central zone of the anterior capsule were cultured in complete medium (F-12 nutrient mixture supplemented with 5% fetal bovine serum). Human aqueous humor was obtained from 11 patients during cataract surgery. Medium was removed and replaced with medium containing various concentrations of porcine platelet-derived TGF-/?2 or 10% human aqueous humor, with or without anti-TGF/?2 neutralizing antibody. The number of cells was counted at 96 hours.

Inhibitory effect of TGF-beta 2 in human aqueous humor on bovine lens epithelial cell proliferation.

PURPOSE To determine whether transforming growth factor-beta 2 (TGF-beta 2) in human aqueous humor inhibits the proliferation of lens epithelial cells. METHODS Bovine lens epithelial cells (BLECs) obtained from the central zone of the anterior capsule were cultured in complete medium (F-12 nutrient mixture supplemented with 5% fetal bovine serum). Human aqueous humor was obtained from 11 pati...

Effect of cataract surgery on aqueous TGF-beta and lens epithelial cell proliferation.

PURPOSE To study lens epithelial cell (LEC) regulation after experimental cataract surgery in rabbits. The effect of aqueous humor (AqH) on LECs in vitro was investigated and the AqH concentrations of basic fibroblast growth factor (bFGF) and transforming growth factor-beta (TGF-beta) were determined. METHODS Aqueous humor was aspirated immediately before, and 1, 5, 10, 15, and 30 days after ...

Effect of Cataract Surgery on Aqueous TGF-jS and Lens Epithelial Cell Proliferation

RESULTS. Aqueous humor collected after surgery triggered LEC growth on each occasion, except on (postoperative) day 30, in contrast to the effect of normal AqH. Lens epithelial cell proliferation peaked on day 1, displaying a sixfold increase. The bFGF concentration in AqH increased 6to 10-fold after surgery and remained high throughout the experimental period. The AqH concentration of active T...

Identification of transforming growth factor-beta as an immunosuppressive factor in aqueous humor.

The anterior chamber of the eye is an immunologically privileged site. Over the past 15 years, numerous laboratories documented that the privileged status of this unique site is mediated by multifactorial immunoregulatory processes. Among the participating factors is the aqueous humor that circulates in the anterior chamber and is in contact with most of the tissues in the anterior segment of t...

Effect of Transforming Growth Factor-β (TGF-β) on proliferation of gastric epithelial cells in culture

Objective: Helicobacter pylori has a well-established role in the development of gastric cancer. In vitro studies reveal increased proliferation of the gastric mucosa in the presence of H. pylori infection. It has been also shown that production of some cytokines, such as interleukin-1 beta (IL-1b) is in...
