Mammalian olfactory mucosa major cell types

The major cell types of the mammalian olfactory mucosa. In mammals, the olfactory mucosa is composed of the olfactory epithelium and a submucosa. The olfactory epithelium is a pseudostratified epithelium composed mainly of sustentacular cells (SUCs), globose basal cells (GBCs), horizontal globose cells (HBCs), immature olfactory sensory neurons (iOSNs), and mature olfactory sensory neurons (mOSNs). The olfactory ensheathing cells (OECs) are an important cell type populating the submucosa. (Source: Kurian SM, Naressi RG, Manoel D, Barwich AS, Malnic B, Saraiva LR.
