Notch genes encode receptors for signaling pathways that regulate neurogenesis in various
tissues. To better understand the roles of Notch genes in olfactory neurogenesis, we studied
the expression of Notch family in developing mouse olfactory epithelium. In the earliest
stage of olfactory development, Notch1 was observed in the mesenchyme lateral to the
olfactory placode. During the developmental stage, Notch1 was mainly observed around the
basal membrane, while Notch3 was observed in the lower compartment of the olfactory …
