PTX3 increases proliferation of endothelial cells
. (A) Mouse brain endothelial cells (bEND5) treated with PTX3 for 48 h (100 ng/ml) proliferate more than controls (phosphate buffered saline (PBS)-treated). (B) There is a significant and dose-dependent increase in the number of bEND5 cells treated with PTX3. Scale bar: 50 μM. **P < 0.01, ***P <0.001, using One-way ANOVA with Dunnett’s post-hoc test (n = 4). Error bars show SEM.
