A poly[N-(2-hydroxypropyl) methacrylamide] (PHPMA) hydrogel immobilized with the neurite-promoting peptide sequence of xIKVAVx was synthesized and its structure was characterized. The PHPMA-IKVAV hydrogel displayed an interconnected porous structure. The ability of the hydrogel to support axonal outgrowth in the injured adult rats cerebrum cavity and to promote tissue regeneration was evaluated. After implantation for 4, 6, 12 and 18 weeks, the brain sections were processed for histological staining. The obse…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
