Dynamic Changes in PRDM6 Abundance in Mouse DA and Great Vessels
(A) H&E staining of the aorta (AO), ductus arteriosus (DA), and pulmonary artery (PA) at E14.5, E17.5, and P0.5.
(B and C) IF staining of PRDM6, α-SMA, and CD31 at E14.5, E17.5, and P0.5. (B) PRDM6 was detectable in smooth muscle cells, but not in endothelia cells, of the DA at E14.15 and E17.5. Its amounts were diminished in the DA at P0.5. (C) PRDM6 was persistently detected in smooth muscle cells of the aorta at all three embryonic stages without significant variation. Scale bars represent 37 μm.
(D and E) Relative intensities of PRDM6 in the DA (D) and aorta (E) at E14.5, E17.5, and P0.5 in seven mice. L denotes lumen. Arrowheads point toward PRDM6 staining. Error bars denote the SEM.
