Five nontumorogenic cell lines suitable for vaccine production were studied by SEM. It was shown that diploid cell line 41 originated from sheep embryo kidney and also two heteroploid cell lines, line 4921 originated from embryo skin and muscles of the African green young monkey and line 4647 from kidney of the adult monkey, maintained normal cell morphology and normal growth pattern in early and in later passages in cultures. Some alterations in epithelial dense monolayer formation were revealed in the heteroploid cell lines: in line 455 originated from spleen of the adult African green monkey, and in line 4184 originated from line 41. The revealed alterations can be considered as the early morphological signs of the transformation of epithelial cells in culture. These cell lines also retained the stability of their morphological characteristics at the earlier and later passages. All the studied cell lines were free of contaminating agents. |
