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.

- cultureMedium: RPMI 1640, w: 2.0 mM stable Glutamine, w: 2.0 g/L NaHCO3 (Cytion article number 820700a)
- supplements: Supplement the medium with 10% FBS
- dissociationReagent: Accutase
- subculturing: 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.
- freezeMedium: As a cryopreservation medium, use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress.
