Expression of Ntf3 in rat tooth

neurotrophin3; neurotrophic factor 3 (Nt3)

Species: rat
Tooth: molar
Method: in situ hybridization (radioactive), probe:


Initiation stage
Expression: oral epithelium, dental epithelium, dental mesenchyme

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

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

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

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

Expression was in proliferating, nondifferentiated cells..
