Spleen versus pancreas: strict control of organ interrelationship revealed by analyses of Bapx1-/- mice.

Abstract excerpt

During early stages of pancreatic development, the mesenchyme that contributes to the spleen overlies the dorsal pancreatic endoderm. Here, we show that interactions between splenic mesenchyme and pancreas proceed via a highly orchestrated morphogenetic program. Disruption of morphogenesis, as occurs in the Bapx1(Nkx3.2)(-/-) embryo, results in transformation of these tissues into well-organized, ectopic gut-like...
