Evc2 knockout mouse was generated by introducing a stop codon followed by IRES-LacZ.
This IRES-LacZ cassette allows us to identify the Evc2-expressing cells.
Evc2-expressing cells were mainly chondrocytes in the anterior viscerocranium.
Endogenous EVC2 protein was observed in these corresponding cells.
Evc2 deficiency showed abnormal craniofacial bones in the anterior viscerocranium.
