[Composite materials based on chitosan and montmorillonite: prospects for use as a matrix for stem and regenerative...

This paper examines the structural and mechanical properties of composite materials based on chitosan and micro- and nanoparticles of Na-montmorillonite and possibility of application for cultivation and targeted delivery of mesenchymal stem cells and regenerative cells. It's have been shown by addition of Na-montmorillonite biomaterial acquires stability of structural and mechanical properties in the sterilization process the handling of liquid media in cell culture. In vitro studies using dermal fibroblasts and adipose tissue mesenchymal stem cells demonstrated that this material has a set of properties to ensure matrix biocompatibility.
