Fig. 4. Effects of PLTX-treated HaCaT conditioned media on monocyte proliferation (A) and adhesion (B). Cells were exposed for increasing time intervals up to 120 h to HaCaT conditioned media (1 h exposure to 1.0 × 10–11 M PLTX followed by 3 and 23 h culture in toxin-free medium). The results are presented as % of proliferation with respect to untreated controls (100% proliferation, panel A) or % of adherent cells with respect to total cells (panel B) and are the mean ± SE of 6 and 3 experiments performed in triplicate, respectively.
