Figure 5From: Expression of a Y-located human proto-oncogene TSPY in a transgenic mouse model of prostate cancerSchematic diagram illustrating potential patterns of human prostate cancer development and the neoplastic prostate growth in LADY mouse. A, Human prostate cancer originates from prostate epithelial cells; either basal cells or luminal cells [51–53]. Although primary prostate cancer is regarded as multifocal, advanced prostate cancer is postulated to be monoclonal [3]. Cancer associated stromal cells proliferate in the oncogenic processes [60]. B, In the LADY-mouse prostate, ubiquitously expressed T-antigen oncogene enables various types of cells, including stromal cells, to be hyper-proliferative and oncogenic in multiple regions. As the results, cancer could originate from multiple types of progenitor cells.Back to article page
