epstein-barr ( eb ) virus-positive burkitt 's lymphoma ( bl ) cell lines , recently established from tumour biopsies and displaying chromosomal translocations indicative of their malignant origin , can be classified into two broad sets : ( i ) lines growing predominantly as single cells/small clumps whose cell surface markers remain close to those of the original tumour cells , and ( ii ) lines whose growth pattern and cell surface markers have progressed closer to the more `` '' lymphoblastoid '' '' phenotype displayed by all in vitro transformed b-cell lines ( lcls ) of normal origin .
