rat connective tissue mast cells ( ctmc ) of greater than or equal to 99 % purity were investigated in vitro and found to express maximal spontaneous cytotoxicity against the mouse fibrosarcoma cell line wehi-164 ( 56.0 % +/- 2.1 sem ) , the ultraviolet b ( uvb ) -induced , cutaneous fibrosarcoma 5c25 ( 34.7 % +/- 3.4 sem ) , and the human renal cell tumor currie ( 26.8 % +/- 2.0 sem ) at an effector to target ( e : t ) ratio of 80:1 .
