Methods of Palate Culture in Later Palatogenesis: Elevation, Horizontal Outgrowth, and Fusion.

The ex vivo culture of the palate has provided a versatile model in which to study palatogenesis. Dysmorphias of the palate remain one of the most common birth defects globally, with great scope for future research in both normal and dysmorphic palatogenesis. This process can be studied in the mouse model using both the hyperoxic rolling culture of maxillary explants and Trowell-type static cultures, which are optimal for the study of different stages of palate development respectively. Here, we describe both methods: the former for the study of palatal shelf elevation and horizontal growth, and the latter for palatal shelf fusion . Both are applicable in murine embryos cultured at embryonic day 13.5 using nonspecialist equipment.
