The present study evaluates the regenerative activity of a polysaccharide fraction from yerba mate (Ilex paraguariensis St. Hil.) using planarian (Girardia tigrina) as a model. At 10 mg L–1, the polysaccharide fraction improves the regeneration of the head, pharynx, and tail of G. tigrina. At the end of experiment, at 10 mg L–1, the planarians obtained are 22–72% higher than the control group. The planarian fragments exposed to the highest concentration used, i.e., (60 mg mL–1), show signs of toxicity, producing death of some organisms. Thus, the polysaccharide fraction presents a great potential for improving the regeneration of planarian segments, suggesting its potential use in tissue regeneration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
