P-values were obtained by performing a non-parametric Wilcoxon test for multiple comparisons in JMP software (SAS).

Grey boxes indicate tissues/surrogates that are not statistically different (p > 0.05), and values in bold indicate potential surrogates for normal brain and brain tumors in quasi-static in vitro applications.
