AbstractDespite the fact that a lot of methods have been developed for rapid virus detection, classic cell culture is still “the golden standard”. The range of viruses that can be isolated and cultured in cell line systems is often limited by the susceptibility of cells to support viral replication. Since the primary cell culture, the best cellular system available to support replication of a large number of viruses, is very expensive and diffcult to obtain, cell lines, which are easier to manipulate, are commonly used for virus growth and isolation.In two previous papers we described the TV cell line initiated by our team from a laryngeal tumor, which harbors human papillomavirus (HPV) gene sequences. In this paper we analyze its capacity to support virus replication. Depending on the virus, different cytopathic effects were produced. Comparison of viral effect observed on this cell line with the effect obtained on other cell lines has been performed. This cell line might be used in the clinical virology laboratory for virus isolation.

Tubular Arrays

In conjunction with the cultivation and transplantation of cells from human tumors by the Programs of Microbiology and Immunogenetics, virus surveillance by electron microscopy has been routinely employed. Of particular interest in this regard have been 3 cell lines cultured from lymph nodes or spleen of 2 patients with Hodgkin's disease and 1 patient with Letterer-Siwe's disease. Each of these cell lines when transplanted in Syrian hamster neonates conditioned with anti-lymphocyte serum grew as serially transplantable tumors; from such transplants of the 3 cell lines cell cultures were retrieved.Herpes type virus particles (Figs. 1, 2, 3) were found in the primary cultures of all three lines, in frozen thawed aliquots of same, and in cultures retrieved from their tumors growing by serial transplantation in hamsters. No virus was detected in sections of 25 of the serially transplanted tumors. However, in 10 such tumors there were repeated instances of tubular arrays in the cisternae of the endoplasmic reticulum (Fig. 4). On serologic examination the herpes virus was shown to be the Epstein-Barr virus.

Two different cell lines (Be-Wo and Jar) of human gestational choriocarcinoma have been maintained in continuous tissue culture for a period of four and two years respectively without losing the ability to elaborate human chorionic gonadotropin (HCG). Tissue cultures, as revealed by electron microscopy, consisted of small cells with single nuclei. In some instances cell surfaces were provided with microvilli but more often the intercellular spaces were narrow and bridged by desmosomes. However, syncytium was not formed. Endoplasmic reticulum (ER) was poorly developed in both cell lines, except in some Be-Wo cells it was prominent. Golgi complex, lysosomes and numerous free ribosomes, as well as excessive cytoplasmic glycogen, were present in all cells (Fig. 1). Glycogen depletion and concomitant increase of ER were observed in many cells following a single dose of 10 ugm/ml of adrenalin added to medium (Fig. 2).

We have paid attention to the alteration of glycosyltransferase in carcinoma cells, because it might be related to the malignancy of the cells. In this connection, localization of β1-4 galactosyl transferase (β1-4 Gal T) in human endometrial carcinoma cells was examined immunocytochemically using two kinds of cell lines, each of which showed different degree of differentiation.An antibody was purified from the rabbit antiserum against the synthetic peptide, IFNRLVFRGMSC (W89) of human β1-4 Gal T coupled with KLH (keyhole limpet hemocyanine) by protein A column and peptide-affinity column chromatography. The anti-W89 serum reacts to the C-terminus of human β 1-4 Gal T and to both membrane-bound and soluble forms of the enzyme. Cell line of well differentiated endometrial adenocarcinoma (I) and that of poorly differentiated endometrial adenocarcinoma (50B) were cultivated respectively in MEM medium containing 15% FCS and 2 mM glutamine for 4 d at 37°C under 5% CO2. The cells were fixed in a mixture of 4% paraformaldehyde and 0.1% glutaraldehyde in 0.1 M Soerensen’s phosphate buffer (pH 7.4) at 4°C for 30 min, washed with PBS, then freezed and thawed. The indirect method of the peroxidase- labeled antibody technique was used for immunocytochemistry of both LM and TEM on the cell lines. The cells were dehydrated in ethanol and embedded in TAAB 812. Ultrathin sections were observed under a TEM, JEM-100S.
