Neuronal protection in the dorsal horn and ventral horn of the spinal cord in mice injected with saline or DHA and then fed a DHA enriched diet or control diet. Representative images taken from the injury epicentre show that the number of NeuN-labelled cells in the animals treated with saline injection (B and G) and DHA diet alone (D and I) was substantially less than naïve control animals (A and F). Animals receiving a DHA injection alone (C and H) and DHA injection plus DHA diet (E and J) had more NeuN-labelled cells compared with saline-treated animals. Scale bar = 50 μm. (Lim et al., 2010).
