Lack of oncogenic potential of measles virus on Syrian hamster embryo cell cultures.

Mass immunization of children in Iran with live attenuated Sugiyama measles virus adapted to calf kidney cell cultures

Properties of hamster embryo fibroblasts transformed in vitro after exposure to ultraviolet-irradiated herpes simplex virus type 2.

An in vitro method which led to the transformation of hamster embryo fibroblasts after exposure to herpes simplex virus type 2 (HSV-2) inactivated with ultraviolet irradiation is described. The transformed cells (333-8-9) produced tumors when inoculated into newborn Syrian hamsters but not when injected into weanling Syrian hamsters of the same LSH inbred strain. However, after one in vivo pass...

Involvement of prostaglandin synthetase in the peroxidative metabolism of diethylstilbestrol in Syrian hamster embryo fibroblast cell cultures.

The mechanism for induction of tumors by estrogens is still unresolved. Neoplastic transformation of Syrian hamster embryo fibroblasts by diethylstilbestrol (DES) suggests that established principles of chemical carcinogenesis may be involved. The Syrian hamster embryo fibroblast cells provide a system in which now the question can be asked whether the metabolic activation of DES is a prerequis...

Ultrastructural modifications of the cell surface and intercellular contacts of some transformed cell strains.

SUMMARY Normal contact-inhibited and transformed cell cultures have been fixed and embedded in situ for an electron microscopic study of the cell surface and intercellular connections. In a number of experiments, ruthenium red was added to the fixa tives following Luft's technic for visualizing the mucopoly saccharide layer on the cell surface. Cultures of normal rat, Chinese and Syrian hamster...
