From: Cardioprotective responses to aerobic exercise-induced physiological hypertrophy in zebrafish heart
Aerobic exercise training programs promoted angiogenesis. a Staining of cardiac vessels for vegf in both exercise and control groups; the white arrows refer to the positive staining of blood vessels in the heart of zebrafish, scale bar = 20 μm. b Relative fluorescence of vegf for the two groups analysed by ImageJ. c mRNA expression of genes related to angiogenesis in zebrafish heart. Statistical significance was determined using the Student’s t test: ***p < 0.001, ns not significant
