A number of placenta-specific genes (e.g., Tpbp, Plac1, Syncytin, and
retrotransposon-associated genes such as Peg10, Rtl1, Endothelin B receptor,
Insl4, Leptin, Midline1, and Pleiotrophin), enhancer elements (e.g.,
glycoprotein hormone α-subunit) and gene isoforms (e.g., 3βHSD, Cyp19), as well
as placenta-specific members of gene families (e.g., Gcm1, Mash2, Rhox, Esx1,
Cathepsin, PAG, TKDP, Psg,... hiện toàn bộ
