Extra-embryonic endoderm cells were derived from E3.5 blastocysts. When grown at low density, the cell culture consists of two distinct sub-populations: a rounded, highly refractile cell type and a more stellate epithelial-like cell type. When cultured in high-density cultures, cells form a lattice-like structure.
XEN cells express extra-embryonic endoderm markers such as Hnf4 and Foxa2.
