Panc02

The Panc02 cell line is a widely used murine model for studying pancreatic ductal adenocarcinoma (PDAC), the most common and aggressive form of pancreatic cancer. Panc02 cells were originally derived from a chemically induced pancreatic tumor in a C57BL/6 mouse. This cell line is highly relevant in preclinical research because it can be implanted orthotopically in syngeneic mice, mimicking the natural tumor environment and offering insights into the immune responses and therapeutic resistance mechanisms of PDAC.

Research using Panc02 has provided significant insights into PDAC’s immunosuppressive microenvironment. One study showed that Panc02 tumors are heavily infiltrated by regulatory T cells (Tregs), which suppress the antitumor immune response. Treatment with low-dose gemcitabine was found to selectively deplete Tregs in Panc02 tumor-bearing mice, leading to an enhanced antitumor immune response and a modest increase in survival. This suggests that immunomodulation could be a promising therapeutic strategy for PDAC.

In addition to immunotherapy studies, Panc02 has also been used to investigate necroptosis, a form of programmed cell death. Inhibition of Aurora Kinase A in Panc02 cells has been shown to induce necroptosis, which is important for overcoming resistance to apoptosis in PDAC. This provides a potential therapeutic approach to target apoptosis-resistant cancer cells by promoting non-apoptotic cell death pathways.

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.
