Figure Lengend Snippet: Human ectocervical cells (ECT1) were pretreated with fibronectin to block integrin-ligand interactions and then infected with MHV68; 24h after infection, MHV68 was found to be partially blocked from cells treated with fibronectin (Fibronectin) compared to cells treated with MHV68 but no fibronectin (NT)(3 independent experiments) (A). Western blot analysis showed integrin alpha 3 and beta 1 were upregulated in the pregnant cervix of infected mice (B) n=3. Antibodies blocking integrin alpha 3 (MHV68 + anti-integrin a3 ab) partially blocked MHV68 infection, while treatment with non specific IgG (MHV68 + IgG) did not block MHV68 infection as compared to cells only treated with MHV68 (MHV68 only) (Representative of 3 independent experiments with a minimum of 3 animals per group) (C). Significance is denoted by bars and is p <.05.
Article Snippet: Cell culture Immortalized human ectocervical cells (ECT1, ATCC, CRL-2614) were cultured in keratinocyte serum free medium (17005-042, Gibco, Grand Island, NY) with bovine pituitary extract and hEGF supplementation as recommended by ATCC under 5% CO2 at 37°C.
