Figure 3—figure supplement 1

Myocardial movement toward the midline is disrupted in phosphoinositide 3-kinase (PI3K)-inhibited embryos throughout cardiac fusion.

Dorsal views, anterior to the top, of embryos displaying the expression of hand2 in the anterior lateral plate mesoderm (ALPM) at (A, E) 12s, (B, F) 14s, (C, G) 18s, and 20s (D, H), treated with either DMSO (A–D) or 20 μM LY (E–H) at bud stage. (I) Box-whisker plots depict the median distance between the sides of the ALPM. Although, hand2 is properly expressed in LY-exposed embryos, ALPM convergence is affected as early as the 10s stage, with a dramatic difference in convergence starting at 12s. The total number of embryos analyzed (n), from three separate incubations at the noted stages (I) are: n = 34, 33, 31, 32, 34, 34 (DMSO); 32, 29, 30, 34, 31, 28 (20 μM LY), respectively. Dots indicate the distance between ALPM sides per embryo. Student’s t-test: asterisk indicates p-values <0.05. Scale bar, 100 μm. Raw data and full p-values included in the source file.
