High voltage electric pulses, 1000 V/cm, were found to induce cell fusion efficiently when delivered to cells growing in a monolayer culture. The maximum yield of fused cells was about 30% of cells remaining after treatment. Colonies of interspecies hybrid cells between mouse and others also appeared with a frequency of 3 X 10(-4) - 2 X 10(-5) after culturing fused cells in a selection medium that permits the growth of only hybrid cells. This method of electrofusion was applied for complementation analysis of DNA repair-deficient xeroderma pigmentosum cells. Efficient cell fusion was also observed with these human diploid fibroblasts and the resulting heterodikaryons showed a recovery of ultraviolet light-induced unscheduled DNA synthesis to the same extent as in normal cells.

UI MeSH Term Description Entries
D002459 Cell Fusion Fusion of somatic cells in vitro or in vivo, which results in somatic cell hybridization. Cell Fusions,Fusion, Cell,Fusions, Cell
D002478 Cells, Cultured Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others. Cultured Cells,Cell, Cultured,Cultured Cell
D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine). DNA, Double-Stranded,Deoxyribonucleic Acid,ds-DNA,DNA, Double Stranded,Double-Stranded DNA,ds DNA
D004260 DNA Repair The removal of DNA LESIONS and/or restoration of intact DNA strands without BASE PAIR MISMATCHES, intrastrand or interstrand crosslinks, or discontinuities in the DNA sugar-phosphate backbones. DNA Damage Response
D004560 Electricity The physical effects involving the presence of electric charges at rest and in motion.
D005816 Genetic Complementation Test A test used to determine whether or not complementation (compensation in the form of dominance) will occur in a cell with a given mutant phenotype when another mutant genome, encoding the same mutant phenotype, is introduced into that cell.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D014983 Xeroderma Pigmentosum A rare, pigmentary, and atrophic autosomal recessive disease. It is manifested as an extreme photosensitivity to ULTRAVIOLET RAYS as the result of a deficiency in the enzyme that permits excisional repair of ultraviolet-damaged DNA. Kaposi Disease,Kaposi's Disease,Kaposis Disease
