Fig. 7From: IGF-1 overexpression improves mesenchymal stem cell survival and promotes neurological recovery after spinal cord injuryUltrastructural changes at the site of lesion in animals with SCI visualized by transmission electron microscopy. Representative images of spinal cord sections obtained from uninjured or SCI-mice admistered with saline, BMMCs or BMMC-IGF1 are shown. Morphological patterns of collagen fibers (a-d), degeneration vacuoles (e-h) and myelin sheath (i-l) were evaluated, as indicated by black arrows. Scale bar = 5 μmBack to article page
