In situ hybridization of Tbx5 and Nppa in WT and KD chimeric mice at E9.5. The expression pattern of Tbx5 at the mRNA level appeared to be not changed. KD embryos showed an ectopic expression of Nppa around the pre-ventricular septal region, which is frequently observed among embryos with abnormal development of ventricular septum. (PNG 6143 kb)
