these findings demonstrate that tgf-beta 2 is as effective as tgf-beta 1 in inhibiting human b cell function , that small amounts of active tgf-beta 1 are present endogenously in in vitro cultures which partially inhibit b cell function , that two major tgf-beta 1 r cross-linked complexes of 65 and 90 kda are present on normal b cells , and that transformation of b cells may be accompanied by changes in the tgf-beta 1 r .
