Abstract
In this study, we demonstrated a Reverse Thermal Gel (RTG), which is injectable and functionalized with GOs (GO-RTG) that changes at room temperature (24 °C) from a mixture to a three-dimensional (3D) matrix gel soon after approaching its body temperature (37 °C). We also presented investigational evidence, which represents that the system of 3D GO-RTG promotes MCs proliferation as well as alignment, supports in long-standing survival of MCs, and enhances the function of MCs when compared with typical 3D plain RTG system and 2D gelatin control groups. Thus, this system of injectable GO-RTG can be capable of using as a negligibly invasive device for engineering efforts of cardiac tissue.
