Murine models have demonstrated stable expression of olfactory receptors in the OE over time, pointing toward OE cell density as a potential driver of age\u2010related OD. Developmental changes in human OE remain poorly characterized. Herein we assess the structure and function of human OE across the lifespan to better understand normal maturation and age\u2010related degeneration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Superior turbinate biopsies from pediatric and adult subjects were obtained for the culture of three\u2010dimensional olfactory organoids. Immunofluorescence (IF) and reverse transcriptase quantitative polymerase chain reaction (RT\u2010qPCR) were performed to confirm the structural make\u2010up and gene expression of expected OE cell types. Live\u2010cell calcium imaging was performed to assess organoid response to odorants, a surrogate of function.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>IF confirmed that pediatric and adult organoids contain major OE cell populations (e.g., horizontal and globose basal cells, sustentacular cells, and immature and mature olfactory sensory neurons).
