Abstract Studies of the development of the central nervous system would be greatly facilitated by the ability to immortalize neuronal tissue from a broad range of ages. We have previously used somatic cell fusion techniques to generate neuronal cell lines from embryonic mice. To immortalize older neuronal cells, a cell isolation technique was developed to obtain viable septal cells from postnatal day 21 mice. The septal cells were fused to N18TG2 neuroblastoma cells and then cultured in selective medium to isolate septum x neuroblastoma cell lines. The hybrid nature of the lines was verified by chromosome analysis and electrophoretic analysis of glucosephosphate isomerase isozymes. The lines express phenotypes typical of differentiated septal neurons. Many lines morphologically resemble neurons and express the high molecular weight neurofilament protein. Several lines express high levels of choline acetyltransferase activity; others synthesize nerve growth factor. These results demonstrate that young adult neuronal tissue can be immortalized and that hybrid cells express properties of the neuronal parent.
