In situ validation of the protein expression data obtained by immunohistochemistry. For each antibody, 1000 tumor cells were counted and results were expressed as a percentage of positive cytoplasmic staining in two different and most expressive areas. Bars represent standard deviation of results obtained with the 25 GBM and the three populations (astrocytes and oligodendrocytes and neurons) of 3 non-tumorous samples (Nt samples). The expression of four proteins tested (HSP 27, ALDH, DRP-2, DRP-3) was higher in GBM cells than in normal astrocyte or oligodendrocyte populations. All neurons were positive (100%) except for HSP 27 (0%).
