FIG. 6.

Influence of heat-killed bacteria on TER of polarized uterine epithelial cell cultures. Polarized rat uterine epithelial cells, grown on NUNC cell culture inserts, were fed with F12K complete medium prior to treatment with heat-killed (HK) E. coli (A) or heat-killed L. rhamnosus (B) in the apical compartment (control wells received medium). TER was measured after a 24-h incubation with bacteria. Values shown are mean TERs ± standard errors for groups of three to four wells per treatment group. For E. coli, n = 5; for L. rhamnosus, n = 3.
