Expression of decorin in mouse tooth

Dcn; proteoglycan II; Pg II; Pg40

Species: mouse
Location in mouse genome: chromosome 10, 100004365 - 100042703 (UCSC, assembly October 2003)
Tooth: lower molar
Method: in situ hybridization (radioactive), probe:


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: dental papilla, preodontoblasts
No expression: outer enamel epithelium, stratum intermedia, stellate reticulum, preameloblasts, dental sac

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

At P2.6 labeling was intense in the preodontoblasts in the cervical region and weaker in the dental papilla and odontoblasts..
