Expression of BDNF and p75NTR in the post-stroke striatum. <i>A</i>

<p>, BDNF immunolabeling was observed in dextran-Texas Red-filled blood vessels and in astrocytic-like cells. <b><i>B</i></b>,<b><i>C</i></b>, High magnification images from insets depicted in (<b><i>A</i></b>) showing astrocytic-like cells in close proximity to blood vessels. Note that the blood vessels and astrocytes are immunopositive for BDNF. <b><i>D</i></b>, Co-immunolabeling for BDNF and GFAP revealed the presence of BDNF protein in astrocytes. <b><i>E</i></b>, PSA-NCAM⁺ migrating neuroblasts maintained p75NTR expression when de-routed to the injured striatal matrix. The pattern of expression shown in these panels was observed 1 and 2 weeks post-MCAo. Scale bars: <b><i>A</i></b>, 50 µm; <b><i>B–E</i></b>, 10 µm.
