MKN-45 gastric cancer cells have c-Met amplification, wild-type p53, and E-cadherin mutation, widely used for gastric cancer mechanism and therapy testing.
MKN-45 is a human gastric cancer cell line derived from a poorly differentiated gastric adenocarcinoma. These cells originate from the liver and are widely used in research focused on gastric cancer development and the assessment of therapeutic agents. The MKN-45 cell line exhibits wild-type TP53, homozygous deletions of p16^INK4A (CDKN2A) and p15^INK4B (CDKN2B), amplification of the c-MET oncogene, and epigenetic silencing of E-cadherin (CDH1) via promoter hypermethylation – all hallmarks of its diffuse-type gastric cancer origin. MKN-45 cells exhibit a phenotype that includes both normal and metaplastic gastric mucosa, with retained differentiation capacity. MKN-45 is commonly used to study the molecular mechanisms underlying gastric cancer and evaluate potential treatments. The MKN-45 cell line is also routinely used to subculture cells for experiments requiring consistent growth behavior and reproducible gastric cancer modeling.

MKN-45 cells are a human gastric adenocarcinoma cell line commonly used in gastric cancer research, drug screening, and anti-cancer therapy studies.
Thawing cells: Quickly thaw frozen cells in a 37°C water bath for no more than 2 minutes. Gradually transfer the cells into pre-warmed RPMI 1640 complete medium with 10% fetal bovine serum (FBS).
Seeding cells: Transfer the cell suspension to a culture flask and incubate at 37°C in a 5% CO₂ incubator.
Collecting cells:
Suspension cells: MKN-45 cells are partially adherent and partially in suspension. Gently shake the flask to evenly distribute the suspension cells.
Adherent cells: Use trypsin to detach adherent cells. First, remove the old medium and add a small amount of trypsin solution to cover the cells, then incubate at 37°C for 1-2 minutes.
Stopping trypsinization: Add fresh pre-warmed complete medium to neutralize the trypsin, and gently pipette up and down to detach the cells completely.
Centrifugation: Transfer the cell suspension to a centrifuge tube and centrifuge at 300xg for 5 minutes.
Resuspending cells: Carefully remove the supernatant and resuspend the cell pellet in pre-warmed complete medium.
Seeding new flasks: Dilute the cell suspension to the desired density and seed into new culture flasks.
Regularly observe cell morphology under a microscope, noting any changes in shape, confluency, and the presence of abnormal cells or contaminants.
