 Context examples 

This allele, which encodes homeobox protein NANOG, plays a role in both the modulation of transcription by RNA polymerase II and the establishment of embryonic stem cell pleuripotency.

(NANOG wt Allele, NCI Thesaurus)

Notch receptors are important for cell-cell communication, which involves gene regulation mechanisms that control multiple cell differentiation processes during embryonic and adult life.

(Anti-Notch Receptor Monoclonal Antibody OMP-59R5, NCI Thesaurus)

This gene plays a role in the underlying pluripotency of inner cell mass and embryonic stem cells.

(NANOG Gene, NCI Thesaurus)

The approximately 100-amino acid ARID (AT-Rich Interaction Domain) DNA-binding domain occurs in some transcriptional regulators (and perhaps modifiers of chromatin structure) involved in embryonic development, cell lineage, and cell cycle control.

(ARID Domain, NCI Thesaurus)

It gives rise to the embryonic heart.

(Angioblastic Cord, NCI Thesaurus)

A odontogenic neoplasm arising from the epithelial component of the embryonic tooth of undetermined malignancy status.

(Ameloblastoma, NCI Thesaurus/CDISC)

Wnt signaling pathway, which is essential for setting up the entire body pattern during embryonic development, involves glycogen synthase kinase-3 (GSK3).

(ALK Pathway, NCI Thesaurus/BIOCARTA)

Meshwork of embryonic connective tissue in the mesoderm from which are formed the connective tissues of the body and the blood and lymphatic vessels.

(Mesenchyme, NIH CRISP Thesaurus)

It begins in embryonic muscle cells (cells that develop into muscles in the body).

(Alveolar rhabdomyosarcoma, NCI Dictionary)
