5637 is a bladder carcinoma cell line isolated from the urinary bladder of a 68-year-old man with grade II carcinoma. 5637 cells produce and secrete several growth factors, such as SCF, IL-1, IL-6, G-CSF, and GM-CSF. These cytokines are functionally active and can be a valuable source for the culture of growth factor-responsive or dependent hematopoietic primary cells and cell lines. The karyotype modal chromosome number of 5637 cells is 67, ranging from 59 to 71. The stemline modal chromosome number is 67 at 36% and polyploidy at 0.6%. Fourteen marker chromosomes are common to these cells, including 3q+, 11q+, i(13q), t(9q21q), i(17q), i(21q). Additional markers, like der(5)t(5,7)(q31,p11) and 1p, were only found specific to a minor subpopulation, as well as microchromosomes and double minutes (DM). Some cells include one or occasionally two Y chromosomes. 5637 cells are tumorigenic and have been shown to induce tumours in nude mice inoculated subcutaneously. The doubling time of 5637 cells is approximately 24 hours. The isoenzyme profile of 5637 cells consists of isoform 1 of AK-1, ES-D, Me-2 and PGM1, isoform 1 and 2 of GLO-I, isoform B of G6PD, as well as isoform 2 of PGM3. In terms of oncogenes, 5637 cells are positive for FGFR3, PIK3CA, HRAS, KRAS, NRAS, TERT, and CDKN2A but negative for TP53 and belong to the molecular bladder cancer subtype l5637 is a bladder carcinoma cell line isolated from the urinary bladder of a 68-year-old man with grade II carcinoma. 5637 cells produce and secrete several growth factors, such as SCF, IL-1, IL-6, G-CSF, and GM-CSF.

In conclusion, 5637 cells are a valuable tool for cancer research, especially with respect to the study of growth factors, cell division, oncogenes, and bladder cancer.
