Introduction

Human embryo (stage 22) nasal epithelium development.

These notes introduce the development of the sense of smell or olfaction and the associated structures including the nasal placode, olfactory epithelium, olfactory bulb, and vomeronasal organ. Recent research has shown a relationship between what the receptive epithelium is exposed too and how the central neural pathway develops, similar to that shown earlier for the vision system. See also a review on the cell biology of smell.[1]


A French research group has recently been investigating the development of smell in the fetus and in neonates. The nasal epithelium has also been a research "hot topic" as it is one of the few easily accessible sites of adult neural stem cells.


Note the different spellings "odour" (UK) or "odor" (USA). Anosmia is the term used to describe having no sense of smell. Anosmia/hyposmia is related to the absence or hypoplasia of the olfactory bulbs and tracts.

Some Recent Findings

  • Dynamic changes in ultrastructure of the primary cilium in migrating neuroblasts in the postnatal brain[2] "New neurons, referred to as neuroblasts, are continuously generated in the ventricular-subventricular zone of the brain throughout an animal's life. These neuroblasts are characterized by their unique potential for proliferation, formation of chain-like cell aggregates, and long-distance and high-speed migration through the rostral migratory stream (RMS) toward the olfactory bulb (OB), where they decelerate and differentiate into mature interneurons. ... Together, our results highlight a close mutual relationship between spatiotemporal regulation of the primary cilium and efficient chain migration of neuroblasts in the postnatal brain. Immature neurons (neuroblasts) generated in the postnatal brain have a mitotic potential and migrate in chain-like cell aggregates toward the olfactory bulb. Here we report that migrating neuroblasts possess a tiny cellular protrusion called a primary cilium. Immunohistochemical studies with zebrafish, mouse, and monkey brains suggest that the presence of the primary cilium in migrating neuroblasts is evolutionarily conserved. Ciliogenesis in migrating neuroblasts in the RMS is suppressed during mitosis and promoted after cell cycle exit. Moreover, live imaging and three-dimensional electron microscopy revealed that ciliary localization and orientation change during saltatory movement of neuroblasts. Our results reveal highly organized dynamics in maturation and positioning of the primary cilium during neuroblast migration that underlie saltatory movement of postnatal-born neuroblasts."
  • Review - Development of the human olfactory system[3] "This chapter focuses on the development of the human olfactory system. In this system, function does not require full neuroanatomical maturity. Thus, discrimination of odorous molecules, including a number within the mother's diet, occurs in amniotic fluid after 28-30 weeks of gestation, at which time the olfactory bulbs are identifiable by MRI. Hypoplasia/aplasia of the bulbs is documented in the third trimester and postnatally. Interestingly, olfactory axons project from the nasal epithelium to the telencephalon before formation of the olfactory bulbs and lack a peripheral ganglion, but the synaptic glomeruli of the future olfactory bulb serves this function. Histologic lamination of the olfactory bulb is present by 14 weeks, but maturation remains incomplete at term for neuronal differentiation, synaptogenesis, myelination, and persistence of the normal transitory fetal ventricular recess. Myelination occurs postnatally. Although olfaction is the only sensory system without direct thalamic projections, the olfactory bulb and anterior olfactory nucleus are, in effect, thalamic surrogates. For example, many dendro-dendritic synapses occur within the bulb between GABAergic granular neurons and periglomerular neurons. Moreover, bulbar synaptic glomeruli are analogous to peripheral ganglia of other sensory cranial nerves. The olfactory tract contains much gray as well as white matter. The olfactory epithelium and bulb both incorporate progenitor cells at all ages."
  • Common olfactory ensheathing glial markers in the developing human olfactory system[4] "To address this gap in knowledge we undertook an immunocytochemical analysis of the 11-19 pcw human foetal olfactory system. Human foetal OECs in situ possessed important differences compared to rodents in the expression of key surface markers. P75NTR was not observed in OECs but was strongly expressed by human foetal Schwann cells and perineurial olfactory nerve fibroblasts surrounding OECs. We define OECs throughout the 11-19 pcw human olfactory system as S100/vimentin/SOX10+ with low expression of GFAP. Our results suggest that P75NTR is a robust marker that could be utilised with cell sorting techniques to generate enriched OEC cultures by first removing P75NTR expressing Schwann cells and fibroblasts, and subsequently to isolate OECs after P75NTR upregulation in vitro. O4 and PSA-NCAM were not found to be suitable surface antigens for OEC purification owing to their ambiguous and heterogeneous expression."

  • The perceptual logic of smell[5] "Mammals have ∼1000 different olfactory receptor subtypes, each responding to a number of different odorants, and each odorant activating a number of different receptor subtypes. These molecular and anatomical underpinnings of olfaction imply a perceptual structure of very high dimensionality that relies on combinatorial coding. In contrast to this expectation, the study of olfactory perception reveals a structure of much lower dimensionality. Moreover, a low-dimensionality approach to olfaction enabled derivation of perception-based structural metrics for smell. These metrics provided meaningful predictions of odorant-induced neural activity and perception from odorant structure alone. Based on this low functional dimensionality, we speculate that olfaction likely does not functionally rely on 1000 different receptor subtypes, and their persistence in evolution may imply that they have additional roles in non-olfactory functions such as in guidance of embryogenesis and development.
  • The dual origin of the peripheral olfactory system: placode and neural crest[6] "The olfactory epithelium (OE) has a unique capacity for continuous neurogenesis, extending axons to the olfactory bulb with the assistance of olfactory ensheathing cells (OECs). The OE and OECs have been believed to develop solely from the olfactory placode, while the neural crest (NC) cells have been believed to contribute only the underlying structural elements of the olfactory system. ...Examination of these transgenic mice revealed GFP-positive cells in the OE, demonstrating that NC-derived cells give rise to OE cells with morphologic and antigenic properties identical to placode-derived cells. OECs were also positive for GFP, confirming their NC origin. Cell lineage tracing studies performed in chick embryos confirmed the migration of NC cells into the OE. Furthermore, spheres cultured from the dissociated cells of the olfactory mucosa demonstrated self-renewal and trilineage differentiation capacities (neurons, glial cells, and myofibroblasts), demonstrating the presence of NC progenitors in the olfactory mucosa."
  • Loss-of-function mutations in sodium channel Nav1.7 cause anosmia.[7] "Loss of function of the gene SCN9A, encoding the voltage-gated sodium channel Na(v)1.7, causes a congenital inability to experience pain in humans. Here we show that Na(v)1.7 is not only necessary for pain sensation but is also an essential requirement for odour perception in both mice and humans."
  • The cell biology of smell[1] "The olfactory system detects and discriminates myriad chemical structures across a wide range of concentrations. To meet this task, the system utilizes a large family of G protein-coupled receptors-the odorant receptors-which are the chemical sensors underlying the perception of smell. Interestingly, the odorant receptors are also involved in a number of developmental decisions, including the regulation of their own expression and the patterning of the olfactory sensory neurons' synaptic connections in the brain. This review will focus on the diverse roles of the odorant receptor in the function and development of the olfactory system."
  • Maturation of the olfactory sensory neurons by Apaf-1/caspase-9-mediated caspase activity[8] "Although the apoptotic role of caspases has been largely understood, accumulating evidence in Drosophila suggests that caspases also control other processes than apoptotic cell death. However, how caspases contribute to the development of the mammalian nervous system remains obscure. Here, we provide unique evidence that Apaf-1/caspase-9-mediated caspase signaling regulates the development of olfactory sensory neurons (OSNs), which includes axonal projection, synapse formation, and maturation of these neurons."

Nasal Placode

(Nasal)

The olfactory epithelium develops from the paired nasal placodes, each develop initially with two components, a medial and lateral region.

In the mouse, gonadotropin-releasing hormone-1 neurones control the release of gonadotropins from the anterior pituitary and were thought to originate from the adenohypophyseal placed. A recent study has shown that the real origin is associated with the formation of the nasal placode.[9]

Olfactory Epithelium

Adult - pseudostratified columnar epithelium overlying a lamina propria

Five basic cell types:

  1. horizonatal basal cells - not present embryonically.
  2. globose basal cells - transit amplifying progenitors of the olfactory epithelium.
  3. sustentacular cells - aligned on the surface with thin cytoplasmic projections terminating at the basal lamina.
  4. olfactory receptor neurons - located in an intermediate zone between basal and apical layers, form the bulk of the epithelium.
  5. olfactory gland cells (Bowman's gland/duct complex) - extend from the glands in the lamina propria to the ducts within the epithelium. Function to carry secretions to the apical epithelial surface.


Olfactory Ensheathing Cells

  • neural crest in origin.[6]
  • accompany and ensheath the small olfactory axons of the nonmyelinated olfactory nerves.
  • compartmentalize the small olfactory axons into fascicles.
  • allow regenerating olfactory nerves to cross the peripheral/central nerve threshold.
Links: neural crest

Olfactory Receptors

Odours bind to and activate olfactory receptors located on the dendrites of sensory neurons in the nose and how the mitral cells of the olfactory bulb (OB) process olfactory information. What has yet to be thoroughly described is how the piriform cortex receives and transforms information arriving from the OB via the lateral olfactory tract (LOT). Although the cell types present in the piriform cortex are known (Shepherd, 2004), previous work has failed to differentiate between disparate electrophysiological profiles and synaptic contacts made between principal cells.

Vomeronasal Organ

The vomeronasal organ (VNO, vomeronasal accessory olfactory system, Jacobson's organ) is involved in detecting and transfering pheromone information through the vomeronasal nerve (nervus vomeronasalis) to the neuroendocrine hypothalamus. This signaling pathway can be used for mating and as olfactory cues for nocturnal animals. There are two families of receptors located in the vomeronasal organ the V1Rs and the V2Rs, are thought to detect pheromonal signals.[15]

Human embryos also have a vomeronasal organ, though later many structures such as the vomeronasal nerve, accessory olfactory bulb and chemoreceptor cells within the organ are lost. Therefore it is not clear whether there is any postnatal neuroendocrine role for this structure.[17][18]

Terms

  • glomerulus - the functional unit of the olfactory bulb.
  • odorant - a compound that elicits the perception of smell.
  • odorant receptor - (OR) a receptor expressed by an olfactory sensory neuron. Receptor belongs to the G protein–coupled receptors (GPCR) superfamily. There are multiple families of odorant receptors, which include the OR (the largest family), TAAR, V1R, V2R, and formyl peptide-like receptors.
  • olfactory cortex - refers to the brain regions that receive direct input from the olfactory bulb are responsible for the perception of smell and for generating odor-evoked behaviours. The five brain regions are the: piriform cortex, anterior olfactory nucleus, olfactory tubercle, entorhinal cortex, and amygdala.
  • olfactory glomeruli - spherically shaped regions of neuropil where information is passed from sensory neurons to postsynaptic neurons.
  • vomeronasal organ (VNO, Jacobson's organ) A neural structure forming part of olfactory system that functions in the detection of pheromones. In humans, the vomeronasal nerve, accessory olfactory bulb and chemoreceptor cells within the organ are lost. Named after Ludwig Lewin Jacobson (1783 – 1843) a Danish surgeon who identified it in 1813.
