Fig 1: Catalase and GPx activity in HUVEC plated on different ECMs. In-gel assays to assess the activity of catalase and GPx (band intensity) in HUVEC cultured in gelatin or laminin showed that (A) catalase activity was similar between cells cultured in the two ECMs, whereas (B) GPx activity in cells cultured in the presence of laminin was lower than when cultured in the presence of gelatin (a.u., arbitrary units; values show the mean and SEM; N=5; two-tailed Student's t test, **p=0.005).
