The growth-promoting activity in the culture supernatant of bovine lymphoblastoid B-cell lines (BL2M3 and BL312) were examined. BL2M3 cells proliferated well in response to conditioned medium (CM) obtained from BL2M3 and BL312 cell cultures. These BL2M3 and BL312 CM were used as sources of BL2M3 cell growth-promoting factor (BL2M3-GPF). BL2M3-GPF was sensitive to acid (pH 2) and alkali (pH 10) and was heat-labile. Proliferative responses of BL2M3 cells were not induced by human recombinant (r)IL 1, rIL 2, rIL 6, granulocyte-colony stimulating factor (rG-CSF) or tumor necrosis factor (rTNF)-alpha. Human low molecular weight B cell-growth factor (LMW-BCGF) was, however, capable of augmenting the proliferation of BL2M3 cells. BL2M3 cells formed clusters in response to LMW-BCGF, whereas they showed single and discete appearance in the presence of BL2M3-GPF. These results suggested that bovine lymphoblastoid B-cell lines might release and respond to the growth-promoting factor for in vitro proliferation of its own cell line, BL2M3.
