In collaboration with our ENT/Otolaryngology colleagues in Boston, we have developed a biorepository that provides both stored and fresh samples to collaborators for the advancement of biomedical research. Samples are obtained from participants undergoing elective sinus surgery and include sinus tissue, nasal polyp tissue, nasal fluid, nasal scrapings, nasal brushings, plasma/serum, peripheral blood mononuclear cells, and urine. Participants with the following medical diagnoses are included in the repository: aspirin-exacerbated respiratory disease (AERD), chronic rhinosinusitis with nasal polyposis (CRSwNP), chronic rhinosinusitis without nasal polyposis (CRSsNP), other sinus diseases, and healthy volunteers. All samples are linked to a clinical database as well. We have established protocols for all stages of cell processing and analysis, including histopathologic techniques as well as freezing, thawing, and culturing of isolated cells. Further, we regularly perform sinus tissue digestion and cell isolation through flow cytometric sorting, as well as single cell RNAseq from cell suspensions. Notable protocols have been published in peer-reviewed journals. These samples are stored within the Laidlaw Lab and are available to collaborators so that ongoing and future multidisciplinary research can be carried out.
