The cancer stem cell (CSC) model is experimentally supported, with varying CSC frequencies explained by cancer type and host. Plasticity between stem cells and differentiated cells could impact CSC models and cancer therapies.
Area of Science:
- Oncology
- Stem Cell Biology
- Cellular Plasticity
Background:
- The existence of cancer stem cells (CSCs) is debated, with some studies questioning their validity.
- Understanding the relationship between normal stem cells and CSCs is crucial for cancer research.
Purpose of the Study:
- To examine the experimental evidence supporting the CSC model.
- To investigate the potential plasticity between stem cells and differentiated cells, specifically via epithelial-mesenchymal transition (EMT).
- To assess the implications of CSC plasticity for cancer therapy.
Main Methods:
- Literature review and analysis of existing experimental data on stem cells and CSCs.
- Examination of studies on the epithelial-mesenchymal transition (EMT) and its relation to stem cell differentiation.
Main Results:
- The CSC model is supported by robust experimental evidence.
- Observed variations in CSC frequencies are attributable to differences in cancer types and experimental hosts.
- Evidence suggests potential plasticity between stem cells and their differentiated progeny, possibly involving EMT.
Conclusions:
- The CSC model remains a valid framework for understanding cancer biology.
- The potential plasticity of CSCs has significant implications for developing novel cancer therapeutic strategies.
- Further research into CSC plasticity is warranted to refine treatment approaches.

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
