Abstract: A total of forty-one tumor infiltrating T cell lines (TIL) were cloned, in the presence of interleukin-2, from nine breast tumor and five melanoma specimens with limiting dilution in a microculture system. Nineteen (46%) of the lines/clones reacted to autologous tumor targets. The T cell receptor (TcR) V beta gene usage was analyzed using polymerase chain reaction (PCR) technique and a set of oligonucleotide primers specific for 20 V beta families. T cell lines generated from paired peripheral blood lymphocytes (PBL) under similar condition were used as control. Our data revealed a limited heterogeneity in TcR V beta gene usage with a biased expression of V beta 6 in both breast tumor- and melanoma-derived TIL lines/clones. In contrast, a random pattern of TcR V beta usage was observed in 27 control T cell lines derived from PBL of patients with breast cancer and melanoma. The results lend support to oligoclonal expansion of TIL at tumor sites but fail to directly correlate the preferential expression of V beta 6 with the functional property of the TIL in recognition of tumor antigens.
