Nasal epithelial cells, obtained through superficial scrape biopsy of human volunteers, are expanded and transferred onto tissue culture inserts. Upon reaching confluency, cells are grown at air liquid interface, yielding cultures of ciliated and non-ciliated cells. Differentiated nasal epithelial cell cultures provide viable experimental models for studying the respiratory mucosa.

We describe here a method for biopsying olfactory mucosa from rat and human nasal cavities. These biopsies can be used for either identifying molecular anomalies in brain diseases or isolating multipotent adult stem cells that can be utilized for cell transplantation in animal models of brain trauma/disease.

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

FAQs
The inspired oxygen concentration delivered by nasal prongs is not fixed. It changes with the selected oxygen flow rate, the patient's breathing pattern, and how much breathing occurs through the mouth. More room-air mixing or greater mouth breathing can alter the final concentration, so the same flow setting may not produce identical inspired oxygen levels in every patient.
Unlike a face mask, nasal prongs leave the mouth and much of the face unobstructed. This design supports speech, eating, and greater mobility while oxygen is being provided. The comparison is therefore practical as well as technical: both interfaces can deliver supplemental oxygen, but the nasal route may be more compatible with routine communication and movement.
Nasal prongs are suited to situations in which a patient requires mild to moderate respiratory support and supplemental oxygen remains appropriate through a noninvasive interface. Their use is especially relevant when clinicians also value communication, eating, or mobility. This places them between the need for oxygen support and the practical demands of acute, recovery, or ongoing care.
An uncomplicated setup connects the oxygen source to the prongs, positions the small tubes at the entrance of the nostrils, and allows oxygen to flow into the nasal passages. The delivered gas then mixes with room air during inspiration. This sequence explains why both equipment connection and appropriate nasal positioning matter to the intended delivery pathway.
Use spans acute care, recovery, and long-term oxygen therapy. In acute care, the interface can support patients who need supplemental oxygen; during recovery, it offers a less restrictive option than a face mask; for long-term therapy, its compatibility with speech, eating, and mobility can support daily activities while oxygen is delivered.
Beyond oxygenation, the interface can preserve everyday functions that a face mask may make less convenient. Patients can speak and eat while receiving oxygen, and greater mobility may be possible because the face is less covered. These features explain why comfort and simplicity matter clinically, particularly when oxygen support must continue during activity or over longer periods.
