TABLE 3.

Transendothelial electrical resistance (TEER) of bEnd3 monolayers exposed to different culture conditions.

Serum-free media (% of 10% FBS control) Astrocyte-conditioned media (% of 10% FBS control)
Day 1 89.7 ± 4.6 97.5 ± 3.0
Day 2 94.9 ± 5.4 98.4 ± 4.3
Day 3 86.9 ± 10.7 79.0 ± 3.0
Day 4 81.7 ± 11.0 92.7 ± 7.3
Day 7 96.2 ± 7.0 92.2 ± 2.7

bEnd3 cells were grown on Transwell™ filters and exposed to different culture media for 4 days. Values are given as percent of control (10% FBS) TEER readings. There was no significant change in TEER readings with any of the culturing conditions used. Control (10% FBS) TEER readings ranged from 100–140 Ω·cm2, n=3–8 measurements, mean ± SEM.
