A) Overall myogenesis protein expression profiles detected by Western blot after 2-week differentiation in gelatin, Matrigel®, ECM, Alg-G-H, Alg-G-H-ECM, HA-HP and HA-HP-ECM coating conditions. B) Myogenesis protein expression of hSMPCs induced with 1% FBS after 1 week and 2 weeks in Alg-G-H, Alg-G-H-ECM, HA-HP and HA-HP-ECM coating conditions. Representative images are shown from experiments performed at least three times.
