These cells exhibit neural, glial, and mesenchymal properties, making them attractive candidates for regenerative medicine, particularly in treating neurodegenerative and immunemediated disorders.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This systematic review analyzed existing literature on the isolation, characterization, and therapeutic applications of olfactory mucosa mesenchymal stem cells.

Their ability to secrete neurotrophic factors such as Brain-Derived Neurotrophic Factor, Nerve Growth Factor, and Glial Cell Derived Neurotrophic Factor underscores their role in neural repair. While most studies successfully isolated olfactory mucosa mesenchymal stem cells via biopsy, differences in sampling depth and culture media influenced cell yield and growth patterns. Preclinical studies suggest that olfactory mucosa mesenchymal stem cells (OM-MSCs) may represent a promising experimental model for neurological disorders\u2014including Parkinson\u2019s disease, spinal cord injury, schizophrenia, and retinal diseases\u2014although current evidence remains preliminary and translational efficacy has not yet been established. However, challenges remain in standardizing protocols, addressing donor variability, and ensuring clinical safety.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Olfactory mucosa mesenchymal stem cells represent a promising avenue for neurological and regenerative therapies.
