They found that the Sonic Hedgehog medulloblastoma subgroup transcriptionally resembled the granule cell hierarchy, group 3 medulloblastoma mirrors Nestin (+) stem cells, group 4 medulloblastoma resembles unipolar brush cells, and PFA/PFB ependymoma and cerebellar pilocytic astrocytoma mirror prenatal gliogenic progenitor cells. Here, NES is linked to medulloblastoma.
