A Simple and Reliable Protocol for the Preparation and Culturing of Fresh Surgically Resected Human Glioblastoma Tissue.

Abstract

Glioblastoma is a heterogeneous glial cell malignancy with extremely high morbidity and mortality. Current treatment is limited and provide minimal therapeutic efficacy. Previous studies were reliant on cell lines that do not accurately reflect the heterogeneity of the glioma microenvironment. Developing reliable models of human glioblastoma is therefore essential. Direct culture of human brain tumours is often difficult and there is a limited number of protocols available. Hence, we have developed an effective method for the primary culture of human glioblastoma samples obtained during surgical resection. Culturing tumour tissue direct from human brain is advantageous in that cultures (1) more closely resemble true human disease, relative to the use of cell lines; (2) comprise a range of cellular components present in the natural tumour microenvironment; and (3) are free of added antibodies and reagents. Additionally, primary glioblastoma cultures are valuable in studies examining the effects of anti-cancer pharmaceuticals and therapeutic agents, and can be further used in live cell imaging, immunocytochemistry, flow cytometry and immunoassay experiments. Via this protocol, cells are maintained in supplemented medium at 37 °C (5% CO2) and are expected to achieve sufficient confluency within 7 days of initial culture.
