Objective: To explore the effect of transcription factor GATA4 on bone formation and mineralization. Methods: Wnt1-Cre mice were mated to GATA4~(fl/fl)mice by cre-loxp gene conditional knockout technique,and conditional knockout GATA4 gene of neural crest cell mice( Wnt1-Cre; GATA4~(fl/fl)) were produced. 2-week-old GATA4 conditional knockout( CKO) mice and wild type( WT)mice were sacrificed and then Micro-CT was conducted to compare the size and volume of craniofacial bones such as calvarial bone,palate bo...
