Abstract

Despite recent advances in the understanding of its cell biology, glioma remains highly lethal. Development of effective therapies requires a cost-effective in vitro tumor model that more accurately resembles the in vivo tumor microenvironment as standard two-dimensional (2D) tissue culture conditions do so poorly. Here we report on the use of a three-dimensional (3D) chitosan-alginate (CA) scaffold to serve as an extracellular matrix that promotes the conversion of cultured cancer cells to a more malignant in vivo-like phenotype. Human U-87 MG and U-118 MG glioma cells and rat C6 glioma cells were chosen for the study. In vitro tumor cell proliferation and secretion of factors that promote tumor malignancy, including VEGF, MMP-2, fibronectin, and laminin, were assessed. The scaffolds pre-cultured with U-87 MG and C6 cells were then implanted into nude mice to evaluate tumor growth and blood vessel recruitment compared to the standard 2D cell culture and 3D Matrigel matrix xenograft controls. Our results indicate that while the behavior of C6 cells showed minimal differences due to their highly malignant and invasive nature, U-87 MG and U-118 MG cells exhibited notably higher malignancy when cultured in CA scaffolds. CA scaffolds provide a 3D microenvironment for glioma cells that is more representative of the in vivo tumor, thus can serve as a more effective platform for development and study of anticancer therapeutics. This unique CA scaffold platform may offer a valuable alternative strategy to the time-consuming and costly animal studies for a wide variety of experimental designs.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
