Description
Established by transfecting cultures of primary astrocytes from brain frontal cortex tissue of 1 day old sprague-dawley rats with a DNA construct containing the oncogenic early region of SV40. Transcriptional control was effected using the human GFAP promoter (pGFA-SV-TE) and the murine phosphoglycerate kinase promoter (pPGK-neo). Cloning was achieved using G418. The cells are phenotypically similar to type 1 astrocytes. CTX TNA2 displays 20% positive staining for glial fibrillary acid protein (GFAP) and a beta alanine inhibitable high affinity uptake mechanism for gamma amino butyric acid (GABA). Alpha-2-macroglobulin production is similar to that found in primary astrocytes, but transferrin production is reduced. The cell line has been shown not to produce proenkephalin A, galactoceebroside or to express the 04 or A2B5 epitopes characteristic of type 2 astrocytes. Immunostaining has shown the SV40 T antigen to be present in over 95% of cells.
