  • Title: [Expression of malignancy traits in the interspecific somatic hybrids of tumor and normal cells].
    Author: Kakpakova ES.
    Journal: Genetika; 1983 Nov; 19(11):1845-50. PubMed ID: 6317520.
    Abstract:
    Tumorigenicity and anchorage independence in two types of the interspecies hybrids of the tumor and normal mammalian cells were studied. One hybrid type was derived from fusion of spontaneously transformed Chinese hamster and normal mouse cells; the second type was obtained by fusion of SV40-transformed Djungarian hamster and the same mouse cells. The tumorigenicity in the athymic nude mice was suppressed in the first type of hybrids. The hybrid clones derived from fusion of SV40-transformed and normal cells could form tumor in nude mice. Testing of hybrid clones for their ability to form colonies in soft agar showed that all hybrids grew well in the medium, similar to tumor parental cells. These data suggest that malignancy and anchorage independence are under separate genetic control. The influence of the origin of the tumor parental cells (spontaneous or SV40-virus transformation) on the expression of the malignancy in hybrids of the tumor and normal cells is discussed.
