Figure 7 p75NTRa in situ hybridization in sections. III. Mesoderm-derived structures. (A) Sagittal
section through stage 45/46 esophagus and pharyngeal mesenchyme. es, esophagus; ph, pharynx.
(B) Sense strand control. (C) Sagittal section showing expression in cloaca at stage 45/46. clo,
cloaca. (D) Sense strand control. (E) Parasagittal section showing expression in stage 45/46 axial
skeletal muscle. p75NTR mRNA appears to be concentrated in the center of the muscle fibers. Somite
boundaries are indicated by dotted lines. (F) Sense strand control. (G) Hematoxylin stained section
through somites at the same stage as tadpole shown in (E). Row of nuclei is delimited with arrows.
