Tissue-level phenotypes of Zswim8−/− embryos. (A) Heart defect in Zswim8−/− embryos. Shown are representative images of H&E-stained transverse sections of hearts from Zswim8+/− and Zswim8−/− littermates at E18.5. Arrowhead points to a VSD. (B) Sacculation defect in Zswim8−/− embryos. Shown are lung sections from Zswim8+/+, Zswim8+/−, and Zswim8−/− embryos at the indicated developmental times immunostained for Podoplanin and Pro-surfactant C (green and magenta, respectively) and stained for DNA (Hoechst; blue). Scalebar represents 100 μm.
