The generation and characterization of human monocyte hybridomas.
Fusion of interferon-gamma activated peripheral blood monocytes to a mutagenized hypoxanthine-guanine phosphoribosyltransferase (HGPRT)-deficient U937 parent line was performed resulting in the generation of a series of unique cloned monocyte hybridomas. These cell lines were proven to be true hybrids by the acquisition of donor class I antigens as well as other donor derived chromosomes. In addition, novel functional characteristics were observed including secretion of specific monokines and the acquisition of phagocytic capabilities. The ability to generate immortalized human monocyte hybridomas will allow for more in depth analysis of monocyte subpopulations and dissection of specific monocyte functions.
