Differential gene expression in the developing SG. Expression of Egf (a), Hh (b), and Bmp (c) family members in epithelial and mesenchymal compartments of the SG at embryonic day 13. Expression patterns were derived from a pre-existing microarray database available online (http://sgmap.nidcr.nih.gov/sgmap/sgexp.html).
