Schematic of myogenic differentiation from human tonsil-derived mesenchymal stem cells (T-MSCs). (A) The undifferentiated T-MSCs were induced to form (B) spheres of approximately 50–100 µm in diameter on a Petri dish. (C) The T-MSCs grew out of the sphere when transferred to the collagen-coated dish in the replating medium and formed a rosette-like spread. (D) The plated cells were cultured for 2 weeks in myogenic induction medium and their morphology was altered; they underwent fusion with one another to generate nascent myotubes. Original magnification, ×40. lgDMEM, low-glucose DMEM; NEAA, non-essential amino acids; ITS, insulin-transferrin-selenium.
