Figure 4. Xic1 is required for heart formation. TIc expression in Xic1Mo injected embryos at stage-29/30 (A–D) and stage-33/34 (E–H), demonstrating the range of cardiac phenotypes from normal expression of TIc (D and H, score = 3) to no expression of TIc (A and E, score = 0). (J) Graph summarizing the percentage of stage-29/30 embryos with hearts of sizes 0 to 3, as assayed by TIc expression, following injection with 20 ng of CTRMo or Xic1Mo and rescued by co-injection with Xic1mRNA (30 pg). n = 58–130 embryos per injection. Transverse sections of stage-33/34 embryos, after injection with CTRMo (K and K′) or Xic1Mo (L and L′), Tropomyosin (red), phH3 (green), DNA in nuclei (Hoechst, blue). §Myotome is also positively labelled by tropomyosin. (M) Total number of cardiomyocytes (blue or red) and the proportion of phH3 cardiomyocytes (green) in five separate stage-33/34 embryos, injected with either CTRMo or Xic1Mo. (N) Average total number of cardiomyocytes (blue or red), and the number of dividing cardiomyocytes (green) from embryos shown in graph M (*P = 0.022, n = 5).
