BBCE cell proliferation. Cells were treated with bFGF (1 ng/ml) and the recombinant proteins. The data are expressed as percentages of the stimulation obtained with bFGF alone, 0% being the basal growth level. (A) Inhibition of BBCE cell proliferation. ■, 16K hPRL; ♦, 16K hPL; ●, 16K hGH; ▴, 16K hGH-V. (B) Stimulation of BBCE cell proliferation in presence of bFGF. □, hPRL; ⋄, hPL; ○, hGH; ▵, hGH-V. Each point represents the mean of triplicate wells. The experiments were repeated at least three times, with similar results.
