Analysis of chromosome karyotype of oral carcinoma-associated fibroblasts / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>The purpose of this study was to investigate whether the fundamental genetic character of oral carcinoma-associated fibroblasts changes through contrasting and analyzing the oral carcinoma-associated fibroblasts and the normal fibroblasts of oral mucosa.</p><p><b>METHODS</b>The two kinds of cells were treated with colchicine and microsometic fluid, and then were expanded with cold acetic acid and formalized with methyl alcohol. The cells were observed under the oil microscope after Giemsa staining. The chromosome karyotype of the two kinds of cells was analyzed by Visus 2. 1.</p><p><b>RESULTS</b>There were not obvious differences in the way of chromosome karyotype between the oral carcinoma-associated fibroblasts and the normal fibroblasts of oral mucosa.</p><p><b>CONCLUSION</b>The basic genetic characteristics of the normal cells are conserved in the oral carcinoma-associated fibroblasts, which means the cells have no malignant changes.</p>
