Abstract

The temperature-responsive poly(N-isopropylacrylamide) [PNIPAAm] has been exploited for various biomedical applications. In this work, poly(N-isopropylacrylamide- co-dopamine methacrylamide) [P(NIPAAm- co-DMAAm)] was synthesized for facile surface modification and application to cell sheets. 1H NMR, FT-IR, and GPC confirmed the successful synthesis of P(NIPAAm- co-DMAAm). The lower critical solution temperature was measured to be ca. 29.2 °C by UV-Vis spectroscopy. AFM imaging clearly visualized the transient phase transition of the temperature-responsive polymer bound on silicon substrate by coordination bond formation. Furthermore, the adhesive and temperature responsive P(NIPAAm- co-DMAAm) could be successfully applied to the facile preparation of NIH-3T3 fibroblast cell sheets. [ABSTRACT FROM AUTHOR]

Abstract

A facile in situsupramolecular assembly and modular modification of biocompatible hydrogels were demonstrated using cucurbit[6]uril-conjugated hyaluronic acid (CB[6]-HA), diaminohexane-conjugated HA (DAH-HA), and tags-CB[6] for cellular engineering applications. The strong and selective host–guest interaction between CB[6] and DAH made possible the supramolecular assembly of CB[6]/DAH-HA hydrogels in the presence of cells. Then, the 3D environment of CB[6]/DAH-HA hydrogels was modularly modified by the simple treatment with various multifunctional tags-CB[6]. Furthermore, we could confirm in situformation of CB[6]/DAH-HA hydrogels under the skin of nude mice by sequential subcutaneous injections of CB[6]-HA and DAH-HA solutions. The fluorescence of modularly modified fluorescein isothiocyanate (FITC)-CB[6] in the hydrogels was maintained for up to 11 days, reflecting the feasibility to deliver the proper cues for cellular proliferation and differentiation in the body. Taken together, CB[6]/DAH-HA hydrogels might be successfully exploited as a 3D artificial extracellular matrix for various tissue engineering applications.
