Expression of amelogenin in hamster tooth

Algn; Amg; Amgl

Species: hamster
Tooth: molar and incisor
Method: immunochemistry, antibody: antiserum (rabbit anti-bovine amelogenin)


Bud stage: no expression

Cap stage: no expression

Bell stage: no expression

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

Detected in young odontoblasts..

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

Patter was similar between molar and icisor: Started in polarising preameloblasts, increased, located in early predentine and in young odontoblasts. Restricted to ameloblasts and enamel after the onset of dentin formation.
