Abstract:
Medulloblastoma (MB) is the most common malignant primary intracranial neoplasm diagnosed in childhood. Although numerous efforts have been made during the past few years to exploit novel targeted therapies for this aggressive neoplasm, there still exist substantial hitches hindering successful management of MB. Lately, progress in cancer biology has shown evidence that a subpopulation of cells within the tumour, namely cancer stem cells (CSCs), are thought to be responsible for the resistance to most chemotherapeutic agents and radiation therapy, accounting for cancer recurrence. Hence, it is crucial to identify the molecular signatures and genetic aberrations that characterise those CSCs and develop therapies that specifically target them. In this review, we aim to give an overview of the main genetic and molecular cues that depict MB-CSCs and provide a synopsis of the novel therapeutic approaches that specifically target this population of cells to attain enhanced antitumorous effects and therefore overcome resistance to therapy.
Insights
Childhood medulloblastoma (MB) is challenging to treat due to cancer stem cells (CSCs). Targeting MB-CSCs offers a promising strategy to overcome treatment resistance and improve outcomes.
Area of Science:
- Pediatric oncology
- Cancer biology
- Neuro-oncology
Background:
- Medulloblastoma (MB) is the most common malignant brain tumor in children.
- Current treatments face challenges due to therapeutic resistance.
- Cancer stem cells (CSCs) are implicated in MB recurrence and treatment failure.
Purpose of the Study:
- To review the molecular and genetic characteristics of MB cancer stem cells (MB-CSCs).
- To provide an overview of novel therapeutic strategies targeting MB-CSCs.
- To highlight approaches for overcoming therapy resistance in medulloblastoma.
Main Methods:
- Literature review of recent studies on medulloblastoma and cancer stem cells.
- Analysis of genetic and molecular signatures specific to MB-CSCs.
- Synopsis of emerging targeted therapies for MB-CSCs.
Main Results:
- CSCs contribute significantly to medulloblastoma's aggressive nature and resistance to therapy.
- Specific molecular and genetic aberrations define MB-CSCs.
- Targeting MB-CSCs shows potential for enhanced anti-tumor effects.
Conclusions:
- Understanding MB-CSC biology is crucial for developing effective treatments.
- Targeted therapies against MB-CSCs represent a promising avenue for improving pediatric medulloblastoma management.
- Further research into MB-CSC-specific vulnerabilities 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:...
