General description

Glioblastomas are among the most aggressive forms of cancer, associated with low treatment efficacy and poor survival. Recurring glioblastomas are often resistant to first-line chemotherapies (1). There is much interest in studying drug-resistant forms of glioblastomas in the effort to develop effective therapies.

The CT-2A cell line is derived from a sub-cutaneous, non-metastatic murine glioma (astrocytoma). The originating tumor was classified as poorly differentiated with high vascularity and malignancy (2). CT-2A cells are marked by high levels of complex gangliosides and low distribution of the anti-angiogenic ganglioside GM3, as well as deficiency in the tumor suppressor PTEN/TSC2, a characteristic present in up to 70% of human high-grade glioma cell lines (3,4). CT-2A tumors are wild-type for p53 and recapitulate several features of human high-grade glioma, including high mitotic index and cell density, nuclear polymorphism, hemorrhage, pseudopalisading necrosis, and microvascular proliferation (5,6).

Source:
CT-2A was generated from a malignant astrocytoma formed via implantation of the carcinogen 20-methylcholanthrene in the cerebrum of a C57BL/6J mouse (7). The tumor was maintained through serial intracranial transplants prior to cell line isolation.

Storage and Stability

Store in liquid nitrogen. The cells can be cultured for at least 10 passages after initial thawing without significantly affecting the cell marker expression and functionality.
