Figure 5. Myotube length on engineered constructs.
(a) Representative images of C2C12 skeletal myoblasts cultured on FN-μprinted soft PDMS and μmolded gelatin hydrogels, stained one week (Week 1) and three weeks (Week 3) after initiating differentiation into myotubes. (b) Histograms of myotube lengths in FN-μprinted soft PDMS and μmolded gelatin hydrogels.
