In situ hybridization detection of tachykinin mRNA in blood vessel walls. Blood vessels from focal myositis areas of serial sections from a soleus muscle specimen of the 6w group, non-exercised side (A-D). In situ hybridization (A,C; antisense staining, B,D; sense staining) show that expression of tachykinin mRNA is present in the smooth muscle layers (A, C, asterisks), and also in the endothelial layer (C, arrows). There are no reactions in the sense control (B, D). Magnification x200.
