Summary
Prostate enlargement, including benign prostatic hyperplasia (BPH) and cancer, is poorly understood due to its complex cell types. Research highlights prostatic stem cells in basal layers as key to normal growth and disease development.
Area of Science:
- Urology
- Cell Biology
- Oncology
Context:
- Prostate gland diseases, including benign prostatic hyperplasia (BPH) and prostate cancer, significantly impact men's health.
- The complex cellular and anatomical structure of the prostate contributes to the poor understanding of disease pathogenesis.
- Normal growth and neoplastic disorders uniquely involve different prostatic compartments.
Purpose:
- To review new concepts on the morphogenesis of normal and abnormal growth in the human prostate.
- To elucidate the role of prostatic stem cells in benign and malignant prostate diseases.
- To summarize current understanding of premalignant and malignant transformations within the prostate.
Summary:
- Prostatic stem cells in the basal cell layer are implicated in normal growth, BPH, and prostate cancer development.
- High-grade prostatic intraepithelial neoplasia is a likely precursor to peripheral zone prostate cancer.
- Malignant transformation involves differentiation abnormalities, altered gene expression, and genetic instability, with stromal invasion marked by loss of basal cell phenotype.
Impact:
- Understanding prostatic morphogenesis and stem cell roles can advance BPH and prostate cancer prevention and treatment.
- Identifying premalignant changes and molecular alterations aids in early cancer detection.
- Characterizing androgen-responsive and -insensitive cell populations informs therapeutic strategies for advanced prostate cancer.
