“…Cell culture. Primary cultures of microvascular bovine retinal endothelial cells (BRECs) were isolated from freshly isolated calf eyes by homogenization and a series of filtration steps, as described previously (19). Primary BRECs were cultured in microvascular endothelial cell basal medium (MECBM) with growth supplement (TCS CellWork, Buckingham, U.K.) in fibronectin-coated dishes.…”

“…Tube formation assay. BRECs were sandwiched between two layers of type I collagen gels in 24-well plates at 2.5 ϫ 10 4 cells/well, as previously described (19). The gel was covered with MCDB131 media containing 1% FCS with or without the growth factors, and in vitro tube formation was assessed for defined periods.…”

“…Variations of VE-cadherin expression have also been documented in different in vitro systems. In human umbilical vascular endothelial cells, gamma linoleic acid, a potent inhibitor of tumour-induced angiogenesis, has been shown to decrease VE-cadherin expression and reduce tube formation in matrix (Cai et al 1999). Hepatocyte growth factor/scatter factor, a cytokine increasing migration, motility, and dissociation of human umbilical vascular endothelial cells, was also shown to decrease VE-cadherin expression (Martin et al 2001).…”

“…Um importante estudo mostrou que o GLA inibe não só o VEGF como também a motilidade das células vasculares endoteliais (Cai et al, 1999a). Molecularmente, o GLA é capaz de inibir a angiogênese induzida pelo tumor em células endoteliais vasculares humanas (HUVEC) em parte pela diminuição de VE-caderina e β-catenina, cujo complexo é essencial para a formação e manutenção de novos capilares (Cai et al, 1999b). Um estudo recente demonstrou que o GLA pode aumentar a expressão do RNAm da ocludina, aumentando a resistência elétrica transepitelial (Yamagata et al, 2003), mostrando que esse ácido graxo é importante para regular o crescimento, permeabilidade e diferenciação das células endoteliais.…”
