摘要: A biocompatible polymer mixture for use as a matrix for cellular attachment includes a mixture of at least two polymers selected from the group consisting of: chitosan (CS), polyethylenimine (PEI), poly(L-lactic acid) (PLLA), poly(D-lactic acid) (PDLA), poly(2-hydroxy ethyl methacrylate) (PHEMA), poly(ε-caprolactone) (PCL), poly(vinyl acetate) (PVAc), poly(ethylene oxide) (PEO), poly[(R)-3-hydroxybutyric acid)] (PHB), cellulose acetate (CA), poly(lactide-co-glycolide) (PLGA) and poly(N-isopropylacrylamide) (PNIPAM). Implants making use of the polymer mixtures can support cell attachment, growth and differentiation, and tissue regeneration in vivo.
