Derivation	C4 cells were isolated from a human prostate cancer LNCaP cell subcutaneous xenograft tumor of castrated mouse. LNCaP cells were isolated from a patient lymph node metastasis of prostate cancer.
Comments	The human prostatic carcinoma cell line, LNCaP (1 x 106 cells; passage # 29) as described in Horoszewiez, JS et al. Cancer Research 43:1809-1818, 1983; was co-inoculated into an athymic male nude mouse with (1 x 106) human fibroblasts derived from an osteosarcoma (cell line MS). The nude mouse host was castrated after 8 weeks incubation. A tumor specimen was excised after a total of 12 weeks. The C4 cell line constitutes the in vitro cultured subline grown from the murine host’s tumor. When the C4 sub-line was subsequently co-inoculated with MS osteosarcoma fibroblasts in a castrated athymic male nude mouse host for another 12 weeks by the same protocol described above. Prostatic epithelial cells cultured from the resultant tumor in this host constituted the C4-2 subline. Tumorigenicity & Osseous Metastasis: Orthotopic administration of 1 x 106 resuspended C4-2 cells in both intact and castrated athymic male nude mice yielded 100% tumorigenicity (20/20 and 14/14, respectively). Osseous prostate cancer metasteses were detected in both intact and castrated murine hosts (2/20 and 3/14, respectively

Complete Growth Medium	The base medium for this cell line is 400 mL DMEM plus 100 mL Ham’s F12. To make the complete medium add 10% fetal bovine serum (ATCC 30-2020; heat-inactivate before using), 5 μg/ml insulin, 13.6 pg/ml triiodothyronine, 5 μg/ml transferrin, 0.25 μg/ml biotin, and 25 μg/ml adenine.
Subculturing	Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes. Corning® T-75 flasks (catalog #430641) are recommended for subculturing this product. Remove and discard culture medium. Briefly rinse the cell layer with Dilute 1:5 - 0.05% Trypsin (ATCC catalog # PCS-999-003) in PBS (ATCC catalog # 30-2200)0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor. Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes). Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting. Add appropriate aliquots of the cell suspension to new culture vessels. Cultures can be established between 3x 104 and 6 x 104viable cells/cm2. Incubate cultures at 37°C. Interval: Maintain cultures at a cell concentration between 3 X 104 and 1 X 105 cell/cm2. Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:8 is recommended Medium Renewal: 2 to 3 times per week
Culture Conditions	Atmosphere: air, 95%; carbon dioxide (CO2), 5% Temperature: 37°C
