Glioblastoma multiforme (GBM) is the most common and aggressive type of primary brain tumor. Cancer stem cells (CSC) refractory to the usual therapies has been demonstrated for maintenance of a subset of self-renewing cells producing cancer recurrence. We here propose 1H MRS to study the metabolism in two CSC lines from primary GBM. The CSCs grown as neurospheres are characterised and compared with T98G cells, also from GBM, in order to highlight similarities and differences. The experiments demonstrate that CSC neurospheres host viable and metabolically active cells with neuronal markers such as GABA and glial markers such as gln.
