Chromosome studies on cultured lymphoblast cell lines from cases of new guinea burkitt lymphoma, myeloblastic and lymphoblastic leukaemia and infectious mononucleosis

Chromosome analysis of three lymphoblast cell lines from New Guinea Burkitt lymphoma (QIMR‐GOR, QIMR‐AMB/1 and AMB/2), three lymphoblast cell lines from infectious mononucleosis (QIMR‐DAR, QIMR‐STE and QIMR‐GOE) and two lymphoblast cell lines from leukaemia (QIMR‐WIL and QIMR‐FIN) showed abnormalities associated with Group A, C, and G chromosomes. Each cell line contained diploid and near diploid cells. Some of the cell lines also contained pseudodiploid cells. Extra Group C or Group G chromosomes were found in a proportion of cells from some of the cell lines. Abnormal Group A chromosomes were also found. However, no one abnormality could confidently be assigned to a specific source of origin of the cell line studied.
