Wnt5a Gene Plays a Role in Mouse Embryonic Orofacial Development

抄録

To determine if Wnt5a gene involved in orofacial development, especially secondary palate development, we checked Wnt5a protein and mRNA in wild-type mouse embryos, and also searched Wnt5a knockout mice palates. We found Wnt5a is expressed during orofacial development, especially necessary for normal secondary palate and tongue morphogenesis. Wnt5a deficient mice exhibit cleft palate and abnormal distortion tongue suggests Wnt5a is essential to the palate development. Our data suggested that defection of MEE proliferation in Wnt5a (-/-) secondary palate indicates Wnt5a gene may regulate palate growth.
