2011 MAR 14 - (VerticalNews.com) -- Researchers detail in 'Enhanced rat isletrnfunction and survival in vitro using a biomimetic self-assembled nanomatrix gel,' new data inrnRobotics - Nanotechnology - Biomimetics. According to a study from the United States,rn"Peptide amphiphile (PA) is a peptide-based biomaterial that can self-assemble into arnnanostructured gel-like scaffold, mimicking the chemical and biological complexity of naturalrnextracellular matrix. To evaluate the capacity of the PA scaffold to improve islet function andrnsurvival in vitro, rat islets were cultured in three different groups--(1) bare group: isolated ratrnislets cultured in a 12-well nontissue culture-treated plate; (2) insert group: isolated rat isletsrncultured in modified insert chambers; (3) nanomatrix group: isolated rat islets encapsulatedrnwithin the PA nanomatrix gel and cultured in modified insert chambers."
