---|---|---|---|---|---|---|
0 h | 1 h | 2 h | 3 h | 4 h | 5 h | |
With Matrigel | 141 ± 14 | 144 ± 20 | 146 ± 4 | 147 ± 8 | 144 ± 9 | 136 ± 15 |
Without Matrigel | 161 ± 11 | 174 ± 4 | 166 ± 6 | 165 ± 3 | 157 ± 5 | 156 ± 5 |
TER of Matrigel-grown cells was significantly reduced from that of cells grown without Matrigel only at 2 and 3 h (P = 0.004 and 0.017 respectively, t test). Baseline readings for Matrigel only or filters alone were significantly lower than TER values for cells grown with and without Matrigel (data not shown).
