OS-RC-2 Cells
























General information
Description | The OS-RC-2 cell line is a human renal cell carcinoma (RCC) model established from the tumor of a Japanese male patient diagnosed with clear cell RCC. This cell line exhibits hallmark features of RCC, including the presence of numerous long microvilli on its surface and glycogen granules within its cytoplasm, as observed through electron microscopy. These characteristics align closely with the features of proximal tubular epithelial cells, thought to be the origin of clear cell RCC. OS-RC-2 has proven to be tumorigenic in immunocompromised mice, where the histopathological features of xenograft tumors strongly resemble the original patient tumor. Chromosomal analyses of OS-RC-2 reveal a hypodiploid modal number of 40, with evidence of a marker chromosome and a specific translocation between chromosomes 2 and 13. Additionally, a large subset of the cell population exhibits a hypotetraploid karyotype with a modal number of 75. These genetic features make OS-RC-2 a valuable model for studying chromosomal aberrations and tumor biology in RCC. Further research using OS-RC-2 has shed light on the role of cytokines in RCC, including tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6). Studies have demonstrated that while TNF-α does not induce DNA synthesis or cell proliferation in OS-RC-2, it can stimulate IL-6 production at high concentrations. These findings contribute to understanding the complex interplay of cytokines in RCC progression and the tumor microenvironment, making OS-RC-2 a useful tool for investigating therapeutic interventions in RCC. |

Handling
Culture Medium | RPMI 1640, w: 2.0 mM stable Glutamine, w: 2.0 g/L NaHCO3 (Cytion article number 820700a) |
---|---|
Medium supplements | Supplement the medium with 10% FBS |
Passaging solution | 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. |
Split ratio | 1:2 to 1:4 |
Fluid renewal | 2 to 3 times per week |
Freeze medium | 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. |

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. |
