Summary
Researchers discovered novel cells with slender, filopodia-tipped processes on developing rat olfactory epithelium. These cells may represent a unique cell population involved in olfactory development or migration.
Area of Science:
- Developmental Biology
- Neuroscience
- Cell Biology
Background:
- The developing olfactory epithelium is crucial for establishing the sense of smell.
- Understanding the cellular dynamics during olfactory development is essential for regenerative medicine and understanding olfactory disorders.
Purpose of the Study:
- To investigate and characterize novel cellular phenomena observed in the developing rat olfactory epithelium.
- To identify and describe the morphology and potential function of newly observed cells with slender processes.
Main Methods:
- Scanning electron microscopy (SEM) was utilized to examine the surface of developing olfactory structures.
- Analysis focused on 15 and 16-day-old rat embryos.
Main Results:
- A previously undescribed population of cells was identified on the surface of the developing olfactory epithelium.
- These cells possess single slender processes, often exhibiting filopodia at their distal ends.
- The observed cells are located on the epithelial surface, suggesting potential roles in cell shedding or migration.
Conclusions:
- The findings suggest the presence of a distinct subpopulation of olfactory epithelial cells.
- These cells share characteristics with migratory or neuronal precursor cells, warranting further investigation.
- The observed phenomenon provides new insights into the cellular plasticity and developmental processes within the olfactory system.

01:25Olfaction
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

01:03Olfactory Receptors: Location and Structure
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
01:20Physiology of Smell and Olfactory Pathway
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.

01:20Taste Buds and Receptors
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
