Enamel Organ Sonic Hedgehog (ssh)
• Stellate Reticulum: star-shaped cells with large intracellular spaces Expression
and many GAGs • Acts on transmembrane
• Outer Enamel Epithelium: many cuboidal cells in contact with protein PTCH1 to activate
dental follicle a signalling cascade
• Inner Enamel Epithelium: columnar cells • Expressed in epithelium
• Stratum Intermedium: flatted cells perpendicular to inner enamel of future incisors/molars
epithelium, between stellate reticulum and inner epithelium and tongue (for taste buds)

Epithelial Rests
Cementum of Malassez
Cementoblasts

Bone Morphogenetic Proteins
• Required for bud → cap transition
• Activates cofactors to enhance
transcription of target genes
• BMP4 induces formation of
primary epithelial knot

Late Bell Stage
(Bell Stage) • Dental lamina breaks down and is disconnected from epithelium →
clusters of epithelial cells, which may persist into epithelial pearls
of Serres
• Stellate reticulum collapses at tip of cusp and outer enamel
epithelium brings blood vessels closer to ameloblasts for nutrients
