An Electrical Stimulation Culture System for Daily Maintenance-Free Muscle Tissue Production

Figure 8

Comparison of cross-sections of TEMs. Culture conditions are labeled in the same manner as on the bottom axis of Figure 7. (a) Micrographs of HE-stained cross-sections. Deep purple dots show nuclei and areas in deep and light pink show cytoplasm and collagen gel, respectively. (b) Ratios of peripheral cell-rich regions to the whole. No electrical stimulation with IGF-1 had the highest ratio, almost 25%. The indicates a statistically significant difference against “No p” in each group ( to 6).
