Fig. 4From: Mechanistic insight into activation of MAPK signaling by pro-angiogenic factorsPredicted maximum pERK response. a Maximum pERK in response to FGF (yellow) or VEGF (blue) concentrations varying from 0.01 nM to 2 nM. b Ratio, R, of combination effects to the summation of individual effects in response to FGF and VEGF. Each dot represents one fit. The dots are spread horizontally to avoid overlap of similar responses from different fits. Asterisk indicates statistically significant difference compared with one (p < 0.05). Bars are median ± 95% confidence intervalBack to article page
