Analysis of tumor and brain stiffness. The Kruskal–Wallis test was used to compare stiffness between the normal brain (blue box, n = 25) and the SF126-firefly luciferase-mCherry (FmC) (red box, n = 5), U87-FmC (red box, n = 5), U251-FmC (red box, n = 5), IOMM-Lee-FmC (green box, n = 5), and HKBMM-FmC (green box, n = 5) tumors if there were statistically significant overall differences (upper panel). The Kruskal–Wallis test was performed to compare the stiffness of the normal brain (n = 25), the three types of glioblastoma (SF126-FmC [red box, n = 5], U87-FmC [red box, n = 5], and U251-FmC [red box, n = 5]; i.e. n = 15 in total), and the two types of malignant meningioma (IOMM-Lee-FmC [green box, n = 5] and HKBMM-FmC [green box, n = 5]) if there were statistically significant differences between the normal brain, glioblastoma, and malignant meningioma tissues (lower panel).
