A72

A72 cells are a canine fibrosarcoma cell line derived from a spontaneously occurring tumor in a dog. These cells are used primarily in veterinary oncology research to study the biology, behavior, and treatment responses of canine fibrosarcomas. Their relevance extends to comparative oncology studies, where insights gained from canine cancers can be applied to human cancer research due to the biological similarities between certain canine and human tumors.

The A72 cell line exhibits an adherent, fibroblast-like morphology and is known for its aggressive growth in vitro. It has been utilized to investigate various aspects of cancer cell biology, including proliferation, metastasis, and tumor cell interactions with the extracellular matrix. These cells are particularly valuable for assessing the efficacy of chemotherapeutic agents and exploring new therapeutic strategies, including immunotherapy and targeted therapies.

A72 cells also provide a useful model for studying the molecular pathways involved in tumor growth and progression, such as signaling through the PI3K/Akt, MAPK, and other related pathways. They are instrumental in understanding the genetic and molecular underpinnings of fibrosarcoma, which can help identify potential biomarkers for diagnosis and targets for treatment in both veterinary and human oncology.

37°C, 5% CO₂, humidified atmosphere.

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

2. 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.

3. 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.

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

5. 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.

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

7. 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.

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

Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods.

To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections.

For long-term preservation, place vials in vapor-phase liquid nitrogen at about −150 to −196 °C. Storage at −80 °C is acceptable only as a short interim step before transfer to liquid nitrogen.

Cryopreserved cell lines are shipped on dry ice in validated, insulated packaging with sufficient refrigerant to maintain approximately −78 °C throughout transit. On receipt, inspect the container immediately and transfer vials without delay to appropriate storage.
