The Immortalized Adult Mouse Ventral Prostate Cells (INK4 -/- VP) were derived from a subline of the INK4a mouse, a transgenic knockout that lacks p16INK4a and p19ARF. Both p16INK4aand p19ARF are specific inhibitors of cyclin-dependent kinases Cdk4 and Cdk6 that regulate cell cycle progression. The cells were isolated from the ventral prostate (VP), which is lined by columnar epithelium that exhibits focal folding. The luminal secretory cells in the epithelium produce homogenous slightly basophilic secretion into the lumen of the ventral prostate. This cell line is a useful model for studying the prostate storma-epithelium signalling way, which plays an important role in prostate development and cancer progression.Immortalization Method: Isolated from p16INK4aand p19ARF Knockout Transgenic Mice BioSafety Level: IISpecies: MouseSource Organ: Ventral Prostate Growth Properties: AdherentMorphology: Fibroblast-likePopulation Doubling: N/ASeeding Density: Thaw entire contents into an appropriate T25 flask as specified in the Propagation instructions.Markers: N/ADonor Age: N/ADonor Gender: N/ADonor Ethnicity: N/APropagation: The base medium for this cell line is Prigrow IV medium available at abm, Cat.
