مستخلص: The efficacy of current therapies for skeletal muscle disorders/injuries are limited urging the need for new treatments. Skeletal muscle tissue engineered platforms represent a promising tool to shed light on the pathophysiology of skeletal muscle disorders/injuries and to investigate the efficacy of new therapies. Herein, we developed a skeletal muscle platform composed of aligned and differentiated myoblasts on micropatterned gellan gum (GG)-based hydrogels tailored with a laminin-derived peptide. To this aim, the binding of murine skeletal muscle cells (C2C12) to different laminin-derived peptides (CIKVAVS (V), KNRLTIELEVRTC (T), and RKRLQVQLSIRTC (Q)) and the binding of laminin-derived peptides to chemically functionalized GG was studied. C2C12-binding to peptide V, T and Q was 10%, 48% and 25%, whereas the peptide tethering to GG was 60%, 40% and 31%, respectively. Peptide-biofunctionalized hydrogels prepared with different polymer content showed different mechanics and peptide exposure at hydrogel surface. Cellular adhesion was detected in all hydrogel formulations, but spreading and differentiation was only promoted in peptide Q-biofunctionalized hydrogels and preferably in stiffer hydrogels. Myoblast alignment was promoted in micropatterned hydrogel surfaces. Overall, the engineered skeletal muscle herein proposed can be further explored as a platform to better understand skeletal muscle disorders/injuries and to screen new therapies.
