Although embryonic stem cells (ESCs) and trophoblast stem cells (TSCs) have been successfully derived from cloned embryos, an in vitro counterpart of the primitive endoderm (PrE) lineage has remained unavailable. To address this gap, this study reports the first successful establishment of extra-embryonic endoderm stem cell lines (XENs) from mouse SCNT-derived blastocysts (NT-XENs). Under conventional culture conditions, NT-XENs were generated from hybrid B6D2F1 blastocysts at a high efficiency of 55%, statistically comparable to that of fertilization-derived XEN lines (FD-XENs, 50%), whereas derivation from inbred C57BL/6J SCNT-derived blastocysts was markedly lower (12.5%). Immunofluorescence and NanoString multiplex gene expression profiling confirmed that NT-XENs robustly expressed specific marker genes for PrE/XENs (e.g., <i>Gata4</i>, <i>Gata6</i>, and <i>Sox17</i>), while exhibiting negligible or absent expression of pluripotency and trophoblast markers.

These differences raise a preliminary hypothesis that the NT-XENs might exhibit a slight transcriptional propensity toward a more differentiated state, and potentially reflect lingering traces of SCNT-associated epigenetic errors, such as localized dysregulation of imprinted genes and X-linked transcripts.
