Morphometric analysis of the growth factors influence on fibroblastic phase of inflammation at experimental myocardial infraction
The objective of the study was comparative study of the effect of VEGF and FGF on fibroblastic phase of inflammation by replacing necrotic myocardium on its model of acute myocardial infarction. Model of myocardial infarction in rats was carried out to study the effect of increasing and decreasing c...

The objective of the study was comparative study of the effect of VEGF and FGF on fibroblastic phase of inflammation by replacing necrotic myocardium on its model of acute myocardial infarction. Model of myocardial infarction in rats was carried out to study the effect of increasing and decreasing concentrations of basic fibroblast growth factor (FGF2) and vascular endothelial growth factor (VEGF) on the dynamics of morpho-metric parameters fibroblastic phase. It has been established that the increase of VEGF in the systemic circulation more stimulated the growth of fibroblasts compared to FGF. Thus, the density of fibroblasts in the repair area in VEGF group during all periods of observation values in a group exceeds FGF. Differences were significant at the 7th (295 [249-340] versus 205 [192-275], p = 0.0257) and the 30th day (132 [125-148] versus 88 [81-122], p = 0.0036).
