A and B show the hypoglossus model. SCD-1 mRNA could be only detected in axotomized neurons (arrows). C and D show axotomized Red nucleus neurons. No up-regulation of SCD-1 mRNA could be observed in dark (C) or in bright (D) field analysis. E and F show the Clarke's nucleus (dotted line); no up-regulation could be observed in the axotomized neurons. Arrows indicate the position of neurons in the corresponding bright field microscopy. Scale bars represent 200 µm (A, B) and 50 µm (C-F).
