Recently MRE revealed that tumours derived from human
breast adenocarcinoma MDA-MB-231, rat Glioma RG2 or
human gioblastoma U87-MG cells were softer than healthy
brain tissue, with MDA-MB-231 significantly softer and
less viscous than the other two models. We investigated
the cellular density, microvessel density, myelin
content and collagen content in these models, and showed
that between the tumours, in MDA-MB-231 tumours, cell
density and microvessel density were significantly lower
than the other two models, positive correlated with
MRE-derived elasticity and viscosity. Meanwhile, the
lack of anisotropic structure of intracranial tumours
may underpin their relative softness.
