Primary stromal cells isolated from human various histological/pathological prostate have different phenotypes and tumor promotion role

Background Prostate stromal cells are known to regulate epithelial growth as well as support and maintain epithelial function. However, how stromal cells regulate epithelial cells and what differences among various histological/pathological prostate stromal cells in prostate cancer progression still remain unclear. This study aimed to investigate the different phenotypes of human various histological~pathological prostate stromal cells, and their role in tumor promotion. Methods The different phenotypes of the human normal prostatic peripheral zonal primary stromal cells （NPPF）, transitional zonal primary stromal cells （NPTF）,
