Initial attachment and proliferation of C2C12 skeletal myoblasts. (A) Initial attachment of C2C12 skeletal myoblasts on tissue culture plastic (TCP), PLGA matrices, GO-PLGA matrices, PLGA-Col matrices, and GO-PLGA-Col matrices were measured using a CCK-8 assay at 6 hours after seeding. (B) Proliferation of C2C12 skeletal myoblasts were measured using CCK-8 assay on 1, 3, 5, and 7 days after incubation. The different letters in (A) denote the significant differences between the control and experimental groups, p < 0.05. The different letters in (B) denote the significant differences between the control and experimental groups at the same time point, p < 0.05. If two groups have the same single letter (a, b, c, etc.), there is no significant difference between them. If a group is marked with a dual letter (eg, de), it has a significant difference from the control and other groups marked with ‘a’, ‘b’, or ‘c’, but does not from another group marked with ‘d’.
