Expression of amelogenin in hamster tooth

Algn; Amg; Amgl

Species: hamster
Tooth: molar and incisor
Method: in situ hybridization (radioactive), probe: 180nt


Bud stage
No expression: oral epithelium, dental epithelium, dental mesenchyme

Cap stage
No expression: oral epithelium, outer enamel epithelium, inner enamel epithelium, enamel knot, stellate reticulum, dental papilla, dental sac

Bell stage
Expression: inner enamel epithelium
No expression: oral epithelium, outer enamel epithelium, stratum intermedia, stellate reticulum, dental papilla, dental sac

Late bell
(differentiation) stage
Expression: preameloblasts
No expression: outer enamel epithelium, stratum intermedia, stellate reticulum, dental papilla, dental sac, preodontoblasts

Secretory stage
Expression: ameloblasts
No expression: outer enamel epithelium, stratum intermedia, stellate reticulum, dental papilla, dental sac, odontoblasts

In incisor amelogenin was observed at early and mature stage secretory ameloblasts.
