title: Rescue and isolation of Rb-deficient prostate epithelium by tissue recombination.
abstract: The ability to rescue viable prostate precursor tissue from Rb-/-fetal mice has allowed for the generation of Rb-/-prostate tissue and Rb-/-prostate epithelial cell lines. Herein, we provide a protocol for the rescue of urogenital precursor tissue from mouse embryos harboring the lethal Rb-/-mutation. The rescued precursors can matured as subrenal capsule grafts in athymic mice. Subsequently prostatic tissue can be used as a source for Rb-/-epithelium in a tissue recombination protocol for the generation of chimeric prostate grafts in athymic male mouse hosts. We have also provided a detailed description for isolating and propagating the Rb-/-epithelium from such tissue recombinants as established cell lines. Methods for characterizing the grafts and cell lines by determining the retention of prostate-specific epithelial expression markers, including cytokeratins, the androgen receptor, estrogen receptor beta and the dorsolateral prostatic secretory protein (mDLP) are given.
