638-The Evolution of Stem Cell Models in Medulloblastoma

Paper Talk · Mar 14, 2026 · 23m

This review examines the development of the cancer stem cell (CSC) model specifically within medulloblastoma, the most prevalent malignant pediatric brain tumor. It tracks the shift from early cell-sorting techniques and surface markers like CD133 to modern single-cell RNA sequencing, which reveals a complex landscape of cellular plasticity. The text details how different medulloblastoma subgroups originate from specific developmental lineages in the brain, such as the rhombic lip or granule neuron progenitors. By identifying these tumor-propagating cells, researchers hope to discover…
