Abstract

Mammalian dentitions are highly patterned, with different types of teeth positioned in different regions of the jaws. BMP4 is an early oral epithelial protein signal that directs odontogenic gene expression in mesenchyme cells of the developing mandibular arch. BMP4 was shown to inhibit expression of the homeobox gene Barx-1 and to restrict expression to the proximal, presumptive molar mesenchyme of mouse embryos at embryonic day 10. The inhibition of BMP signaling early in mandible development by the action of exogenous Noggin protein resulted in ectopic Barx-1 expression in the distal, presumptive incisor mesenchyme and a transformation of tooth identity from incisor to molar.

  5. Mandibular arch explants were dissected and cultured as described (3). Beads were also prepared as described (3 4) with Fgf8 and BSA (white) and BMP4 and Noggin (blue) beads at a concentration of 100 μg/mg. Whole-mount digoxigenin (DIG) and sectioned 35 S in situ hybridization were carried out as described (3 4).

  12. E10 and E11 mandibular arch explants were cultured with beads that were placed in the distal (presumptive incisor) mesenchyme for 48 hours in vitro. These were then dissected into incisor and molar regions; the incisor regions were dissected as pairs. Single incisor and molar regions from each mandibular arch were transferred into opposite ends of a kidney under the kidney capsule in adult male mice. These regions were then left to develop for 14 days in vivo. The resulting teeth were photographed placed in Bouin's fixative for 3 days dehydrated and embedded. Sections were stained with alcian blue and chlorontine fast red.
