TissueNA
Tissue SpecificityIsoform 1 is the predominant isoform in serum but is undetectable in follicular fluid. In the embryo, strong expression is seen in the palatal epithelia, including the medial edge epithelial and midline epithelial seam of the palatal shelves. Less pronounced expression is also seen throughout the palatal shelf and tongue mesenchyme (PubMed:31215115). {ECO:0000269|PubMed:15472207, ECO:0000269|PubMed:31215115}.
