Fig. 12. Immunohistochemistry of molecular markers of myogenic progenitor cells
(MPCs) in the fast myotomal muscle of Arctic charr. (A) Pax 7 staining in a
transverse section from a piscivorous morph and (B) FoxK1-
staining in
a transverse section from a large benthic morph. Arrowheads indicate some of
the cells immunopositive for these markers. Scale bars, 50 µm.
