Figure 12.

Reactions in fibroblast-like cells. Sections of a gastrocnemius muscle specimen of the 1-week group, exercised side (a, b), and a soleus muscle specimen of the 6-week group, exercised side (c), are shown. In situ hybridization (antisense staining in (a), (c); sense staining in (b); (b) is from a parallel section to (a)). There is an expression of NK-1R (TACR1) mRNA in the cells in (a). There are no reactions in the sense control (b). Arrows point at fibroblast-like cells. There are also NK-1R mRNA reactions in the fibroblast-like cells in (c) (arrows). Bar = 25 μm.
