An improved culture system for secondary palatal elevation

In Vitro Aims and scope Submit manuscript

Summary

An organ culture system devised for studying the development of the secondary palate was modified so that it retained high partial pressures of oxygen and supported total anterior and posterior palatal elevation. The cultured tissues appeared healthy as judged by histological examination. Medium was continuously recirculated through the culture system in which Day 13 embryonic mouse heads, with the brain and tongue removed, were totally submerged and suspended. The medium was constantly gassed via hollow fiber devices. A motor-driven stirrer, run at a low rate, agitated the medium so that the boundary layer surrounding the tissue was dispersed. Embryonic mouse heads were cultured in each of four media: Eagle's basal medium, Ham's F-12 medium, Fitton-Jackson's modified BGJb medium, and Waymouth's MB 752/1 medium. Elevation of the palate in both anterior and posterior regions with excellent tissue viability was achieved in all heads grown in BGJb medium.
