[Detection of Hep-2 and hepatoma cell line chromosomal aberration by using fluorescence in situ hybridization]
1Department of Biology, Najing Normal University, Nanjing, Jiangsu, 210097 P. R. China.
Objective:
To study the chromosomal aberration of hepatoma cell line (1172) and laryngocarcinoma cell line (Hep-2).
Methods:
Fluorescence in situ hybridization (FISH) was used with nine chromosomal special libraries.
Results:
The abnormal signals indicated that very complicated aberrations existed in the two cell lines. This suggested that the aberrations also existed in other chromosomes not yet studied. In 1172, the major type was structure aberration, but in Hep-2, numerical abnormality was shown in almost all chromosomes studied.
Conclusion:
Compared with traditional cytological methods, this technique has the advantages of being quicker and more accurate and sensitive.
