Fig. 10. TTP is expressed in mononucleated cells that lie beneath the myofiber basal lamina. Co-detection of laminin with Pax7 (A,C,E) or TTP (B,D,F) transcripts in cryosections of TA muscle 1 hour after injury using combined immunofluorescence (E,F) and in situ hybridization (A,B); nuclei are counterstained with Hoechst 33342 (C,D). Pax 7 RNA (A) and TTP RNA (B) are associated with nuclei that lie below a laminin sheath (arrowheads in E,F). The same sublaminar cell (A,C,E or B,D,F, respectively) is indicated by arrows. Interstitial cells that do not express Pax7 or TTP RNA are indicated by `V' arrowhead.
