Abstract:
Recent discoveries have provided the compelling evidence that stem cell populations within each individual tumor are key contributors of therapy failure regardless of whether these populations are transient or stable. Thus, it is becoming increasingly clear that efficient tumor treatment requires eradication of the entire CSC population. The potential role of CSCs in tumor initiation and relapse has motivated an investigation of the CSCspecific treatments. However, development of the therapeutic strategies targeting CSCs might be challenged by a high diversity and plasticity of CSC features. Moreover, taking in account that an origin of CSC remains controversial and accumulating experimental evidence suggests a possibility of tumor cell reprogramming, efficient anti-cancer treatment should eradicate both CSCs and tumor bulk as well as prevent tumor dedifferentiation. In this article we discuss new insights into the stem cell concept of tumor development, review the treatment strategies eradicating CSCs that have been evaluated in preclinical and clinical studies and summarize the strategies to identify new CSC-targeted therapy.
Insights
Targeting cancer stem cells (CSCs) is crucial for effective cancer treatment, as they drive therapy failure and tumor relapse. New strategies must eradicate CSCs, tumor bulk, and prevent dedifferentiation.
Area of Science:
- Oncology
- Cancer Stem Cell Biology
Background:
- Cancer stem cells (CSCs) are implicated in tumor initiation, relapse, and therapy failure.
- The heterogeneity and plasticity of CSCs present challenges for targeted therapies.
Purpose of the Study:
- To review current understanding of the CSC concept in tumor development.
- To summarize therapeutic strategies targeting CSCs evaluated in preclinical and clinical studies.
- To outline methods for identifying novel CSC-targeted therapies.
Main Methods:
- Literature review of preclinical and clinical studies on CSC-targeting treatments.
- Analysis of research on CSC origins and tumor cell reprogramming.
- Synthesis of strategies for CSC identification.
Main Results:
- CSCs, whether transient or stable, are key drivers of treatment resistance.
- Eradicating the entire CSC population is essential for efficient tumor treatment.
- Tumor cell reprogramming and dedifferentiation complicate treatment approaches.
Conclusions:
- Effective cancer therapy requires targeting CSCs, bulk tumor, and preventing dedifferentiation.
- Addressing CSC diversity and plasticity is vital for developing successful treatments.
- Further research into CSC identification and targeted therapies is warranted.

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:...
