CAL-62 Cells
General information
Description | The CAL-62 cell line was established from the right lobe of the thyroid gland of a 70-year-old Caucasian woman in 1988 and has been extensively used in the study of thyroid anaplastic carcinoma. These human epithelial-like cells exhibit a distinctive monolayer growth pattern and demonstrate pronounced tumorigenic properties, making them a significant model for in vivo studies of thyroid cancer progression. When transplanted into immunodeficient nude mice, CAL-62 cells have shown a robust capability to form tumors, providing a practical and effective model to analyze tumor dynamics and evaluate potential therapeutic strategies in real-time biological settings. Characterized by a rapid proliferation rate with a doubling time of approximately 24 hours, CAL-62 enables accelerated research outputs in studies that are time-sensitive, enhancing the efficiency of experimental workflows in cancer research. Genetic characterization of this cell line reveals the presence of the KRAS p.G12R mutation and alterations at the 9p21.3 locus, indicating complex genetic underpinnings associated with thyroid anaplastic carcinoma. This cell line?s stable epithelial phenotype and inherent radioresistance further underscore its utility in uncovering novel insights into the pathophysiology of aggressive thyroid cancers and in the development of new therapeutic modalities. The unique attributes of CAL-62, including its aggressive tumor-forming ability and genetic markers, make it a pivotal resource in the ongoing efforts to better understand and treat thyroid anaplastic carcinoma. |

Handling
Culture Medium | DMEM, w: 4.5 g/L Glucose, w: 4 mM L-Glutamine, w: 1.5 g/L NaHCO3, w: 1.0 mM Sodium pyruvate (Cytion article number 820300a) |
---|---|
Medium supplements | Supplement the medium with 10% FBS |
Passaging solution | Accutase |
Doubling time | 24 hours |
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. |
Split ratio | 1:2 to 1:5 |
Fluid renewal | 2 to 3 times per week |
Freeze medium | CM-1 (Cytion catalog number 800100) or CM-ACF (Cytion catalog number 806100) |
Handling of cryopreserved cultures |

Quality control / Genetic profile / HLA
Sterility | 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. |
