AGS Cell Line

General Information
OrganismHomo sapiens, human
Cell Line DescriptionAGS cells are a human gastric adenocarcinoma cell line derived from gastric tissue of a 54-year-old Caucasian female. AGS cell lines exhibit epithelioid morphology, which is characterized by their invasive growth pattern and tumorigenic potential in vivo. These cells are often used as models to study the molecular and cellular mechanisms of gastric carcinogenesis, including the effects of Helicobacter pylori infection, a well-known risk factor for gastric cancer. AGS cells provide a powerful system to explore the interaction between gastric cancer cells and Helicobacter pylori, particularly with regard to how bacterial factors influence cancer cell proliferation, apoptosis, and inflammatory responses.

Additional InfoAGS cells were persistently infected with parainfluenza virus type 5 (PIV5). This cell line has knockdown of the NOD1 gene and expresses DEFB4 in a NOD1-/cagPAI-dependent manner. These cells can be used to further study the role of NOD1 in H. pylori -induced gastric tumors. AGS cells are also valuable for examining the response of the gastric epithelial barrier to various stimuli, including inflammatory cytokines, and for studying signaling pathways related to gastric cancer, such as those involving NF-kB, Wnt, and MAPK.

Protein Expressionp53 positive
TumorigenicYes, in athymic BALB/c mice.
Mycoplasma TestNegative
Culture Conditions and Handling
Subculturing1. Remove old culture medium from adherent cells and wash with calcium- and magnesium-free PBS. For T25 flasks, use 3-5 ml of PBS and for T75 flasks, use 5-10 ml.
2. Then, completely cover the cells with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks.
3. Allow cells to detach by incubating at room temperature for 8-10 minutes.
4. After incubation, resuspend cells by gently mixing with 10 ml of medium and centrifuge at 300xg for 3 minutes.
5. Discard the supernatant, resuspend the cells in fresh medium, and transfer them to a new flask that already contains fresh medium.
Medium Renewal2 to 3 times per week
Subcultivation RatioThe ratio of 1:2 to 1:6 is recommended.
Culture MediumHam's F12 + 2mM Glutamine + 10% Foetal Bovine Serum (FBS).
Culture ConditionsAtmosphere: Air, 95%; CO2, 5%;Temperature: 37°C
CryopreservationCryopreservation Medium or complete growth media with 10% DMSO.
