GA-reactive T cells in tissue culture produce growth factors. Real-time PCR analyses and GADPH-normalized levels show that compared with non-GA exposed cells (control), treatment of T cells with GA resulted in increase in levels of IGF-1 and PDGFaa. Each circle, square, or triangle within a given growth factor dataset represents a separate culture. *, P < 0.05; **, P < 0.01, compared with non-GA exposed controls (t test).
