Feline spinal cord H&E-stained sections of different groups: (a–e) Control-ve group showing normal histological structure of white matter (b and c) and gray matter (d and e). (f–j) Control + ve group showing (f) severe extensive hemorrhages and necrosis in white matter and (g) diffuse hemorrhages with demyelination of white matter (black arrow). (h) Higher magnification showing hemorrhages, liberation of hemosiderin pigment and axonal spheroid formation (green arrow). (i) Numerous perivascular lymphocytic cuffing in gray matter (arrowhead) with marked hemorrhages. (j) Higher magnification of gray matter showing diffuse gliosis with chromatolysis (red arrow). (k–o) SVF + PRP group showing (i–m) apparently normal white matter and (n–o) apparently normal neurons in gray matter.
