title: Use of thermosensitive polymer material on the basis of N-isopropylacrylamide and N-tert-butylacrylamide copolymer in cell technologies.
abstract: We developed thermosensitive polymer substrates on the basis of N-isopropylacrylamide and N-tert-butylacrylamide co-polymer and studied their interaction with cultured substrate-dependent mammalian cells. It was shown that these polymers promote cell adhesion and proliferation at a level comparable to polystyrene treated for cell culturing and provide effective cell detachment after lowering culturing temperature below a critical level determined by phase transition temperature in aqueous solutions of polymers. A dependence of phase transition temperature on the ratio between N-isopropylacrylamide and N-tert-butylacrylamide was demonstrated. Differences in the dynamics of cell detachment from the surface of polymer substrates with various proportions between the components were shown.
