Expression of follistatin in mouse tooth

Fst

Species: mouse
Tooth: incisor
Method: in situ hybridization (radioactive), immunochemistry, reagent:


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

At E16 expression was in the dental epithelium on both labial and lingual surfaces..

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

By E18 the labial-lingual asymmetry of follistatin expression became progressively evident..
