| Outline of Final Research Achievements |
In order to clarify the control ability of skeletal muscle differentiation of chondroitin sulfate (CS), five types of CS (CS-A, B, C, D and E) were added to myoblast C2C12 which can reproduce skeletal muscle differentiation process, and differentiation was carried out for a certain period of time. The value of myotube fusion index (FI) calculated from the number of nuclei in the myotubes was used as an index of muscle differentiation. As a result, all CS subtypes used in this reserch suppressed myotube formation, among which CS-E showed remarkable suppression. Moreover, myotube FI decreased concentration-dependent manner. Conversely, knocking down the decorin of CS proteoglycan of C2C12, the muscular differentiation promoted in reverse. From the above, it has clarified that CS have a strong potential to regulate the muscle differentiation.
