Summary
We report here on the establishment of aCydia pomonella (Cp) hybrid cell line IZD-Cp 4/13. As there have been no reports on somatic cell fusion involving lepidopteran cell lines so far, we had to develop an appropriate fusion procedure. We first tried—but without much success—to obtain HAT (hypoxanthine, aminopterin and thymidine)- or TAM (thymidine, adenine, and methotrexate)-selectable strains of the threeCydia pomonella cell lines IZD-Cp 2202, IZD-Cp 0508 and Cp 169. We then tried and succeeded in developing a fusion procedure based on the use of biochemically blocked permanent cells as one partner in the fusion. Biochemically inhibited IZD-Cp 2202 cells and embryonic Cp cells were hybridized by polyethyleneglycol treatment. The cells of the hybrid cell line IZD-Cp 4/13 differ from the permanent parental cells (cell line IZD-Cp 2202) with respect to morphology, DNA content isoenzyme patterns, and response to challenge with theChoristoneura murinana nuclear polyhedrosis virus.
