Porous chitosan-hyaluronic acid scaffolds as a mimic of glioblastoma microenvironment ECM.

abstract：:Polymerized high internal phase emulsion (polyHIPE) foams are extremely versatile materials for investigating cell-substrate interactions in vitro. Foam morphologies can be controlled by polymerization conditions to result in either open or closed pore structures with different levels of connectivity, consequently ena...
