For tissue engineering and regenerative medicine, stem cells should be effectively cultured in vitro. New thermoresponsive nanocomposite gels (MD-NC gels), consisting of inorganic clay (hectorite) and copolymers composed of hydrophobic 2-methoxyethyl acrylate (MEA) and hydrophilic N,N-dimethylacrylamide (DMAA) units, could be
