Morphometric analysis of tissue necrosis in ischemic muscle from study group animals. A. Images of hematoxylin-eosin stained m. tibialis anterior sections. Necrotic tissue is marked by black line. (N* - necrotic tissue, B* - border zone, H* - healthy or regenerating tissue). B. Representative images of muscle tissue from different zones of section. Labels: star – vasa in normal muscle tissue with; black dot – inflammatory demarcation zone between anucleic disrupted tissue and regenerating muscle fibers; triangle – regenerating round-shaped muscle fibers with multiple centrally located nuclei. C. Statistical data of necrotic tissue area in “PBS”, “ADSC”, “GFP-ADSC” and “VEGF-ADSC” groups. Measurements made in 4–5 animals per group.
