Expression profiling of transforming growth factor beta superfamily genes in developing orofacial tissue.

ABSTRACT:

Background

Numerous signaling molecules have been shown to participate in the dynamic process of orofacial development. Among these signal mediators, members of the transforming growth factor beta (TGFbeta) superfamily have been shown to play critical roles. Developing orofacial tissue expresses TGFbeta and bone morphogenetic protein (BMP) mRNAs, their protein isoforms and TGFbeta- and BMP-specific receptors. All these molecules display unique temporospatial patterns of expression in embryonic orofacial tissue, suggesting functional roles in orofacial development. For example, the TGFbetas and BMPs regulate maxillary mesenchymal cell proliferation and extracellular matrix synthesis. This is particularly noteworthy in that perturbation of either process results in orofacial clefting
