DGs play a role in Caco-2-BBE cell attachment and spreading on laminin-1 and laminin-2. The time courses of capacitance were measured at 40 kHz during attachment and spreading of Caco-2-BBE cells on electrodes precoated with 10 μg/ml laminin-1 (A1): cells transfected with empty vector (black: t1/2 = 3.00 ± 0.34 h, s = 0.60 ± 0.10 nF/h, n = 4), cells overexpressing DG (gray: t1/2 = 2.75 ± 0.60 h, s = 0.64 ± 0.13 nF/h, n = 4); electrodes precoated with 10 μg/ml laminin-2 (B1): cells transfected with empty vector (black: t1/2 = 16.5 ± 0.8 h, s = 0.16 ± 0.01 nF/h, n = 4), cells overexpressing DG (gray: t1/2 = 31.2 ± 3.5 h, s = 0.10 ± 0.01 nF/h, n = 4). Each trace and bar represents an average of n wells. Half times (t1/2) and apparent spreading rates (s) were determined on laminin-1 (A2) and on laminin-2 (B2). *P ≤ 0.05, **P ≤ 0.005 vs. vector-transfected Caco-2-BBE cells.
