Expression of Wnt7b in mouse tooth

wingless-related MMTV integration site 7B

Species: mouse
Location in mouse genome: chromosome 15, 87202707 - 87248845 (UCSC, assembly October 2003)
Tooth: molar
Method: in situ hybridization (radioactive), probe:


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

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

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

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

Region that is negative for Wnt7b expression region is larger in presumptive incisor epithelium in IKKA null mutant mouse. (Ohazama et al 2004) See expression of IKKA.
