Localization of BDNF mRNA and protein, and baroreceptor fibers in the fetal right subclavian artery (dorsal aspect). Photomicrographs showing localization of BDNF mRNA (A, arrow), BDNF immunoreactivity (C, arrow), and PGP-stained baroreceptor fibers (B, and at higher magnification in D) in sagittal sections through the origin of the right subclavian artery at E16.5. The level depicted in these sections is medial to that shown in Figure 4. Sections inA and C were counterstained with cresyl violet. Abbreviations and scale bars as in Figure 4.
