Fig. 3. The pore size distribution and tubular pore morphology among the scaffold fit with the skeletal muscle tissue engineering needs. (a) Scanning electron microscope (SEM) image of the pores of the cryogel. (b) Diameter distribution of the pores among the 2% gelatin – 1% CMC cryogel. (c) Confocal image of the cryogel anisotropic fibers marked with aminofluorescein in green. (d) Bright field image of the CNT distribution inside the cryogel. SEM image of a CNT is shown in the small inset. Scale bars = 100 μm.
