| Organism | Homo sapiens, human |
| Cell Line Description | 5637 is a cell line that exhibits epithelial morphology and was isolated from the bladder of a 68-year-old Caucasian male patient with grade II carcinoma. The karyotype of 5637 cells has a modal chromosome number of 67, ranging from 59 to 71. 5637 cells produce and secrete multiple growth factors such as SCF, IL-1, IL-6, G-CSF, and GM-CSF. 5637 cells are tumorigenic and have been shown to induce tumors in nude mice inoculated subcutaneously. Oncogene-wise, 5637 cells are positive for FGFR3, PIK3CA, HRAS, KRAS, NRAS, TERT, and CDKN2A, but negative for TP53, belonging to the molecular bladder cancer subtype luminal. 5637 cells are a valuable tool in cancer research, especially in the study of growth factors, cell division, oncogenes, and bladder cancer. |

| Culture Conditions and Handling |
| Subculturing | 1. First, remove the old medium from the adherent cells and wash with PBS without calcium and magnesium. For T25 flasks, use 3-5 ml PBS and for T75 flasks, use 5-10 ml.
2. Then, completely cover the cells with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks.
3. Let the cells incubate at room temperature for 8-10 minutes to allow them to detach.
4. After incubation, gently mix the cells with 10 ml of medium to resuspend, then centrifuge at 300xg for 3 minutes.
5. Discard the supernatant, resuspend the cells with fresh medium, and transfer them to a new flask that already contains fresh medium. |
| Medium Renewal | 2 to 3 times weekly |
| Subcultivation Ratio | The ratio of 1:4 to 1:8 is recommended. |
| Culture Medium | 90% RPMI 1640 + 10% h.i. FBS |
| Culture Conditions | Atmosphere: Air, 95%; CO2, 5%; Temperature: 37℃ |
