  • Title: Prostate cell cultures as in vitro models for the study of normal stem cells and cancer stem cells.
    Author: Miki J, Rhim JS.
    Journal: Prostate Cancer Prostatic Dis; 2008; 11(1):32-9. PubMed ID: 17984999.
    Abstract:
    Current existing therapies for prostate cancer eradicate the majority of cells within a tumor. However, most patients with advanced cancer still progress to androgen-independent metastatic disease that remains essentially incurable by current treatment strategies. Recent evidence has shown that cancer stem cells (CSCs) are a subset of the tumor cells that are responsible for initiating and maintaining the disease. Understanding normal stem cells and CSCs may provide insight into the origin of and new therapeutics for prostate cancer. Normal stem cells and CSCs have been identified in prostate tissue by the use of several markers or techniques. Although research on stem cells has been limited by the lack of suitable in vitro systems, recent studies show that not only primary cells but also several established cell lines may exhibit stem cell properties. This review discusses various in vitro culture systems to propagate normal prostate stem cells and prostate CSCs together with molecular markers. These in vitro cell culture models should be useful for elucidating the differentiation of prostatic epithelium and the biological features of prostate cancer.
