Preliminary identification of the mutant human embryonic lung fibroblast Z-HL_(16)C cell strain / 基础医学与临床

ABSTRACT

Objective To study the characteristics of Z-HL_(16)C cell strain mutated from the human embryonic lung fibroblasts(HL).Methods Morphology observation,chromosome cytogenetics,tumorigenesis in nude mice,and the sensitivity to virus were examined.Results As a transformed cell strain,the Z-HL_(16)C showed polygon shapes liking epithelium;the number of chromosome was sub-triploid or hyper-triploid,and the structures of 30%～40% chromosomes were abnormal.The incidence of its inoculation in nude mice was 100%,and the pathological studies proved its tumorigenesis.The cytopathic effects of many kinds of viruses were observed in Z-HL_(16)C cell strain.Conclusion The Z-HL_(16)C is one of the cancer cell strains transformed from HL cells.
