Figure 6
Semi-quantitative evaluation of outgrowth under various experimental conditions. Migration is comparably extensive in the presence of IGF-I, IGF-II or fibroblast conditioned medium (fbcond), while it is significantly less after removal of IGF-I from the medium (fbpreclear; P < 0.05) or in the presence of TGFβ1 (P < 0.001). The control bar represents experiments in which no medium change was carried out. The vertical axis represents migration units as defined in the methods section.
