Methylcellulose(MC) can have water solubility with an optimum level of thedegree of methyl substitution (typically, DS between 1.7-2.0). MC solutions willundergo a completely reversibly sol-gel phase transition upon heating. Thisthermo-sensitive MC hydrogels have many advantages as tissue engineering materials:high water content, the good elasticity similar to tissues, and good biocompatibility,which will be widely used in macromolecular drug delivery, drug release ,tissuebarriers and tissue engineering bec...
