Cancer stem cells (CSCs) drive tumor formation and metastasis in solid tumors. This perspective defines CSCs, reviews prostate stem cells, and proposes methods to identify CSCs for improved prostate cancer diagnosis and therapy.

Area of Science:

  • Oncology
  • Stem Cell Biology
  • Prostate Cancer Research

Background:

  • Solid tumors harbor rare cancer stem cells (CSCs) responsible for tumor initiation, maintenance, and metastasis.
  • The normal human prostate (NHP) is susceptible to hyperproliferative diseases like benign prostate hyperplasia (BPH) and prostate cancer (PCa).

Purpose of the Study:

  • To define cancer stem cells (CSCs).
  • To review normal prostate stem/progenitor cells and their role in prostate cancer.
  • To present methodologies for identifying tumor-reinitiating CSCs.

Main Methods:

  • Literature review and synthesis of current knowledge on CSCs and prostate stem cells.
  • Discussion of methodologies for CSC identification.
  • Development of a hypothetical model for prostate cancer cell hierarchy.

Main Results:

  • Evidence suggests stem/progenitor cells exist in cultured PCa cells, xenograft tumors, and patient tumors.
  • Proposed methodologies for identifying putative CSCs.
  • A hypothetical model for hierarchical organization of human PCa cells.

Conclusions:

  • CSCs play a critical role in prostate cancer development and progression.
  • Understanding CSCs and their hierarchical organization can inform novel diagnostic, prognostic, and therapeutic strategies for prostate cancer.
  • Further research into CSC identification and targeting is crucial for advancing prostate cancer treatment.
