Comments: The VK2/E6E7 (ATCC CRL-2616 cell line was established in 1996 from the normal vaginal mucosal tissue taken from a premenopausal woman undergoing anterior-posterior vaginal repair surgery. [52983]

The ectocervical Ect1/E6E7 (ATCC CRL-2614) and endocervical End1/E6E7 (ATCC CRL-2615) cell lines were established in 1996 from normal epithelial tissue taken from a premenopausal woman undergoing hysterectomy for endometriosis. [52983]

Cells at passage 3 were immortalized by transduction with the retroviral vector LXSN-16E6E7 in the presence of polybrene. Clones were selected in medium containing G418. [52983]

The endocervical cell line expresses characteristics of simple columnar epithelium, whereas the ectocervical and vaginal cell lines express characteristics of stratified squamous nonkeratinizing epithelia. [52984]

Without stimulation, all three cell lines produce macrophage colony-stimulating factor (M-CSF), transforming growth factor beta1, interleukin 8 (IL-8), prostaglandin E2, the secretory leukoproteinase inhibitor, and the polymeric immunoglobulin receptor. [52984]

The endocervical cell line (End1/E6E7), but not the others, also produce the lymphopoietic cytokines IL-6, IL-7, and consistently detectable levels of the chemokine known as "regulated-upon-activation, normal T cell expressed and secreted" (RANTES). [52984]

Stimulation with interferon gamma and tumor necrosis factor alpha (TNF alpha) induces or significantly up-regulates expression of several of the cytokines and chemokines as well as major histocompatibility complex (MHC) class II antigens in the lines. [52984]

Piliated, but not nonpiliated, Neisseria gonorrhoea strain F62 variants actively invade these epithelial cell lines.VK2/E6E7細胞 Invasion of these cells by green fluorescent protein-expressing gonococci is characterized by colocalization of gonococci with F actin. [53415]

These cell lines may provide the basis for valid, reproducible in vitro models for studies on cervicovaginal physiology and infections and for testing pharmacological agents for intravaginal application.

Propagation: ATCC complete growth medium: Keratinocyte-Serum Free medium (GIBCO-BRL 17005-042) with 0.1 ng/ml human recombinant EGF, 0.05 mg/ml bovine pituitary extract, and additional calcium chloride 44.1 mg/L (final concentration 0.4 mM)

Atmosphere: air, 95%; carbon dioxide (CO2), 5%

Temperature: 37.0°C

Subculturing: Protocol: The cells should not be allowed to become confluent, subculture at 60 to 90% of confluence. Remove medium, and rinse with 0.25% trypsin, 0.53mM EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37C) until the cells detach.VK2/E6E7細胞 Neutralize the trypsin by adding a 1:1 mixture of Dulbecco's modified Eagle's medium and Ham's F12 medium containing 10% fetal bovine serum. Centrifuge the cell suspension at 1000 rpm for 10 minutes, resuspend the pellet in fresh serum-free growth medium, aspirate and dispense into new flasks. Cells will not attach well for 24 hours after subculture.

Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:5 is recommended

Medium Renewal: Every 2 to 3 days

Preservation: Freeze medium: A 1:1 mixture of Dulbecco's modified Eagle's medium and Ham's F12 medium, 85%; fetal bovine serum, 10%; DMSO, 5%

Storage temperature: liquid nitrogen vapor phase

Doubling Time: 24 hrs
