Low and high power views of recombinant-IR in striatal cells from rats sacrificed at 1 month after gene transfer with vectors that express a specific transcription factor from the use the INS-TH-NFH promoter, or a control that expresses TH. The photomicrographs show areas proximal to the needle tracks. (A and B) The control vector, pINS-TH-NFHflag-th/ires/aadc, TH was detected using flag-IR, (A) low power or (B) high power. (C and D) pINS-TH-NFHflag-lsd1/ires/lac, LSD1 was detected using flag-IR, (C) low power or (D) high power. (E and F) pINS-TH-NFHmyc-clock/ires/lac, CLOCK was detected using c-myc-IR, (E) low power or (F) high power. (G and H) pINS-TH-NFHmyc-clock/ires/lac, Co-REST was detected using c-myc-IR, (G) low power or (H) high power. Scale bars: (A,C,E, and G) 100 μm; (B,D,F, and H) 50 μm.
