CERV-186 Cells

The CERV-186 cell line, derived in vitro from the xenotransplant of cervical carcinoma MRI-H-186, serves as a biological model for invasive, large-cell, non-keratinizing squamous cell carcinoma. This cell line was established and adapted for in vivo transplantation under the direction of Dr. Bodgen at the Mason Research Institute. Characterized by its genomic properties, MRI-H186 contains approximately 26 integrated copies of both full-length and truncated forms of the HPV16 genome, which significantly influence its transcriptomic profile.

MRI-H186 cells are distinguished by their robust expression of both full-length and truncated early HPV16 transcripts, notably displaying high levels of E5 full-length (fl) RNA. This transcriptional signature is notably distinct from that observed in other cervical carcinoma cell lines such as CaSki and MRI-H196. Additionally, the transcriptional activity of MRI-H186, in terms of the expression of various other transcripts, shows a close alignment with the patterns observed in the HPK-IA and C3 cell lines, indicating a similar transcriptional behavior across these models. The presence of both full-length and truncated HPV16 genomic integrations in MRI-H186 cells is a key factor in their vigorous expression of early viral transcripts, particularly underscored by the significant expression of E5 fl RNA. This intense transcriptional activity culminates at the early polyadenylation signal, highlighting the unique transcriptional dynamics within the MRI-H186 cell line.

DMEM:Ham's F12, w: 3.1 g/L Glucose, w: 1.6 mM L-Glutamine, w: 15 mM HEPES, w: 1.0 mM Sodium pyruvate, w: 1.2 g/L NaHCO3 (Cytion article number 820400a)

Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium.

After thawing, plate the cells at 5 x 10^4 cells/cm^2 and allow the cells to recover from the freezing process and to adhere for at least 24 hours.

Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

Upon receipt, either store the cryovial immediately at temperatures below -150° C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

For immediate culturing, swiftly thaw the vial by immersing it in a 37° C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

When planning to store a cryovial in liquid nitrogen for future thawing, it is mandatory to adhere to stringent safety measures. Appropriate protective gloves and clothing are essential, and the use of a face mask or safety goggles is required during the transfer of frozen samples to or from the liquid nitrogen tank. This is to mitigate the risk of injury from potential cryovial explosions upon removal, which can result in the projection of sharp fragments.
