Fig. 8

Pacemaker CMs do not differentiate in RA-deficient embryos. (A,B) IHC of Isl1 (green), Mhc (red), Amhc (blue) in hearts of DMSO- and DEAB-treated embryos at 48 hpf. Number of embryos examined: DMSO-treated n = 25, DEAB-treated n = 21. Arrows in A and B indicate Isl1 expression and the lack of Isl1 at the venous poles of the hearts in control and DEAB-treated embryos, respectively. (C,D) IHC of GFP (green), Mhc (red), Amhc (blue) in hearts of DMSO- and DEAB-treated sqet33-mi59B embryos at 48 hpf. Number of embryos examined: DMSO-treated n = 11, DEAB-treated n = 11. Arrows in C and D indicate the sqet33-mi59B GFP expression and its reduced expression at the venous poles of the hearts in control and DEAB-treated embryos, respectively. The remaining sqet33-mi59B expression in DEAB-treated embryos is adjacent to the atrial CMs. Views are ventral with anterior up. Scale bar – 50 μm.
