Abstract

All four mammalian fasciclin-containing genes are expressed in the adult valves and are localized in partially overlapping and reciprocal patterns during cardiovascular development. Spatiotemporal comparison of the fasciclin-containing secreted adhesion genes, TGFbeta induced clone H3 (βigH3) and periostin, revealed that they are co-localized within the outflow tract endocardial cushions, but that βigH3 expression is restricted to the septal cushions within the atrioventricular canal. Conversely, the fasciclin-containing transmembrane gene, stabilin-1, is predominately expressed in the endocardial layer overlaying the cushions and lining the developing heart. However, expression of the fasciclin-containing transmembrane gene, stabilin-2 is only present in the post-natal mature valve endothelial cells. These data illustrate for the first time that the primitive endocardial cushions dynamically express multiple fasciclin-containing adhesion molecules as they undergo the key steps of seeding, proliferation, differentiation, fusion, mesenchymal condensation and remodeling during mouse heart development.
