Abstract In mammalian hearts myocardial infarction produces a permanent collagen-rich scar. Conversely. in zebrafish a collagen-rich scar forms but is completely resorbed as the myocardium regenerates. The formation of cross-links in collagen hinders its degradation but cross-linking has not been well characterized in zebrafish hearts. https://parisnaturalfoodes.shop/product-category/organic-oat-fiber/
