[Cytogenic characteristics and virogenic status of lymphoid cells from malignant baboon lymphomas].

Four lymphoid cell cultures obtained from Papio hamadryads with malignant lymphomas were studied. The cultured cells produced two lymphotropic EBV-like herpes virus of Papio (HVP) and T-lymphotropic monkey retrovirus STLV-1 (HTLV-1 family) or HVP alone. More than 100 subcultured cell lines were shown to remain mixed B- and T-cellular, the levels of T cells of different subpopulations were 15-50%.

[The cytogenetic characteristics of B-lymphoid lines from Papio hamadryas baboons and Macaca arctoides brown macaques].

A cytogenetic analysis of 9 permanent suspension cell lines was performed. Cell lines were obtained from Papio hamadryas and Macaca arctoides cells by different methods. Five cell lines originated from non-malignant parental cells.

[The cytogenetic characteristics of human B-lymphoblastoid cell lines].

Permanent suspension B-cell lines HSL-1, HSL-2, HSL-3, HSL-4, HSL-5, HSL-8, HSL-9 have been obtained spontaneously from lymphocytes and cells of hematopoietic tissues of patients with various forms of leukemia and tumours. All cell lines contained Epstein-Barr virus (EBV). At early stages of cultivation (6-39th passages) normal karyotypes were established for all the tested lines which testified their origin from normal B-lymphocytes.

[The isolation and characteristics of continuous virus-producing lymphoid suspension cultures of African green monkey cells].

Five continuous lymphoid suspension cell cultures were established by cultivation of lymphocytes from African green monkeys. The immunological typing revealed the mixed pattern of cultures consisting of B and T cell types. Two types of viruses: herpesvirus and retrovirus C-type were demonstrated by electron microscopy.
