Cancer stem cells (CSCs), also known as tumor-initiating cells or cancer-initiating cells, are a small subpopulation of cells within a tumor with distinctive characteristics. These cells have the ability to self-renew and differentiate into various cell types that constitute the bulk of the tumor. They are thought to play a critical role in the initiation, growth, and recurrence of cancer. CSCs heavily interact with the tumor microenvironment, including the surrounding stromal cells, blood vessels, and immune cells. These interactions can promote CSC self-renewal, support tumor growth and spread, and shield CSCs from immune attacks. One of the most significant implications of CSCs in cancer therapy is their inherent resistance to standard treatments like chemotherapy and radiation. Conventional treatments typically target rapidly dividing cells, but CSCs are often slow-cycling and possess enhanced DNA repair mechanisms, making them less susceptible to these therapies. Understanding the biology of CSCs may pave the way for the development of targeted therapies designed to eradicate the root cause of cancer, potentially revolutionizing cancer treatment in the future.
In recognition of this relevant field, BMC Cancer has published this Collection which encouraged submissions on:
- CSC identification and characterization
- CSC markers and biomarkers
- Mechanisms of CSC self-renewal and differentiation
- CSC interactions with the tumor microenvironment
- Role of CSCs in cancer initiation and progression
- Strategies to target and eradicate CSCs
- CSCs and cancer recurrence
- CSCs and treatment resistance
