In mouse embryos, the chemokine receptor Cxcr4 is expressed in mesoderm and definitive endoderm, the two tissue types that are formed by ingression through the primitive streak (McGrath et al. 1999). Expression of Cxcr4 in mouse definitive endoderm later decreases at the stage when hindgut is formed (McGrath et al. 1999). NODAL signaling activates expression of CXCR4 through phosphorylated SMAD2 and SMAD3 (Brown et al. 2011). EOMES and GATA6, transcription factors expressed in the primitive streak and endoderm, also directly activate expression of CXCR4 (Chia et al. 2019).
