Thermoresponsive cationic copolymer brushes for mesenchymal stem cell separation.Thermoresponsive, cationic, copolymer brushes poly(N-isopropylacrylamide(IPAAm)-co-N,N-dimethylaminopropylacrylamide-co-N-tert-butylacrylamide(tBAAm)) and poly(IPAAm-co-3-acrylamidopropyl trimethylammonium chloride-co-tBAAm) were prepared on glass substrates through surface-initiated atom transfer radical polymerization.  Prepared copolymer brushes were investigated as thermally modulated cell separation materials.  During observation of cell adhesion and detachment properties on copolymer brushes, human bone marrow mesenchymal stem cells (hbmMSC) exhibited thermally modulated cell adhesion and detachment, while other bone-marrow-derived cells did not adhere.
