Abstract:
Glioblastoma stem cells (GSCs) are cells with a self-renewal ability and capacity to initiate tumors upon serial transplantation that have been linked to tumor cell heterogeneity. Most standard treatments fail to completely eradicate GSCs, causing the recurrence of the disease. GSCs could represent one reason for the low efficacy of cancer therapy and for the short relapse time. Nonetheless, experimental data suggest that the presence of therapy-resistant GSCs could explain tumor recurrence. Therefore, to effectively target GSCs, a comprehensive understanding of their biology and the survival and developing mechanisms during treatment is mandatory. This review provides an overview of the molecular features, microenvironment, detection, and targeting strategies of GSCs, an essential information required for an efficient therapy. Despite the outstanding results in oncology, researchers are still developing novel strategies, of which one could be targeting the GSCs present in the hypoxic regions and invasive edge of the glioblastoma.
Insights
Glioblastoma stem cells (GSCs) drive tumor recurrence due to resistance to standard treatments. Understanding GSC biology is crucial for developing effective glioblastoma therapies targeting these resilient cells.
Area of Science:
- Neuro-oncology
- Cancer Stem Cell Biology
- Glioblastoma Research
Background:
- Glioblastoma stem cells (GSCs) possess self-renewal and tumor-initiation capabilities, contributing to tumor heterogeneity.
- Standard glioblastoma treatments often fail to eradicate GSCs, leading to disease recurrence and poor therapeutic efficacy.
- Therapy resistance in GSCs is a key factor in glioblastoma relapse.
Purpose of the Study:
- To provide a comprehensive overview of glioblastoma stem cell (GSC) biology.
- To discuss the molecular features, microenvironment, detection, and targeting strategies for GSCs.
- To highlight the necessity of understanding GSC mechanisms for developing efficient glioblastoma therapies.
Main Methods:
- Review of existing scientific literature on glioblastoma stem cells.
- Analysis of molecular characteristics and microenvironmental factors influencing GSCs.
- Examination of current and emerging GSC detection and targeting strategies.
Main Results:
- GSCs are implicated in glioblastoma heterogeneity and treatment failure.
- Understanding GSC survival and developmental mechanisms is mandatory for effective therapy.
- Targeting GSCs in hypoxic regions and invasive edges presents a potential novel strategy.
Conclusions:
- Glioblastoma stem cells are critical therapeutic targets due to their role in tumor recurrence.
- A thorough understanding of GSC biology is essential for improving glioblastoma treatment outcomes.
- Novel strategies, including targeting GSCs in specific tumor microenvironments, are under development.
