Expression of laminin alpha 2 in mouse tooth

Lama2

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


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

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

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

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

Expression was localized to polarized odontoblasts and lost from secreting odontoblasts.
