Isolating nasal olfactory stem cells from rodents or humans.

Area of Science:

• Neuroscience
• Stem Cell Biology
• Regenerative Medicine

Background:

• The olfactory mucosa is a unique, accessible nervous tissue exposed to the external environment.
• It offers a non-invasive alternative to post-mortem tissue for studying brain diseases.
• The olfactory mucosa contains adult stem cells crucial for continuous neurogenesis.

Purpose of the Study:

• To present methods for obtaining olfactory mucosa biopsies in rats and humans.
• To describe the purification and characterization of olfactory ecto-mesenchymal stem cells (OE-MSCs).
• To highlight the potential of OE-MSCs for disease research and cell therapy.

Main Methods:

• Biopsy of olfactory mucosa from rats and humans.
• Enzymatic separation of lamina propria from the epithelium.
• Purification of stem cells using enzymatic or non-enzymatic methods.
• Culturing, banking, and differentiation of purified OE-MSCs.

Main Results:

• Established safe biopsy methods for olfactory mucosa.
• Successfully purified OE-MSCs, demonstrating high proliferation and differentiation potential.
• OE-MSCs show promise for studying neurodevelopmental and neurodegenerative diseases.
• OE-MSCs are viable candidates for cell therapy applications.

Conclusions:

• Olfactory mucosa provides an accessible source of adult stem cells (OE-MSCs) for research and therapy.
• OE-MSCs can be readily isolated, expanded, and differentiated into neural cells.
• These findings support the use of OE-MSCs in comparative omics studies and regenerative medicine.
