Fig. 5 Leftward Displacement of CPCs and Cardiac Rotation Are Affected upon Reduced or Ectopic BMP Signaling (A–C) Selected images of confocal time-lapse recordings of laf/alk8 (A) heat-shock induced (at 15-somite stage) tg(hsp70:noggin3) (B) and tg(hsp70:bmp2b) (C) embryos with individual cells marked and tracked over a 200 min period. (D) Quantification of clockwise cardiac cone rotation in wild-type laf/alk8 mutant tg(hsp70:noggin3) and tg(hsp70:bmp2b) embryos (mean ± SEM). (E) ISH with a cmlc2 riboprobe on tg(hsp70:bmp2b) embryos heat shocked at various time points (indicated at the top). Arrows and arrowheads indicate CPCs not properly incorporated into the cardiac tube. Heat shock at 15-somite stage, no cardiac jogging (n = 14/16); 18-somite stage, no cardiac jogging (n = 12/20); 22-somite stage, leftward jogging (n = 17/19).
