Description
Sample Type: Cells, Tissue: nasal epithelial cells (level II region), Tissue Harvest Methods: The nose was dissected to isolate the Level II region of both nostrils. The maxillo turbinate and olfactory epithelium were discarded and the lateral meatus and nasoturbinate were retained for cell isolation. The dissected nasal sections were rinsed with cold phosphate buffered saline to remove the blood. After rinsing, a 5 ml buffered mixture of proteases (collagenase, 80 U/ml, Sigma-Aldrich; pronase, 10 mg/ml, Sigma-Aldrich; HEPES, 0.1 M) in Hams F12 medium (Invitrogen, Carlsbad, CA) was added to the nose and incubated at 37°C for 40 minutes to remove the epithelial cell layer. Following incubation, the mixture was vortexed and the resulting cell suspension was collected in a clean centrifuge tube. The cell suspension was centrifuged (200 x g, 10 min, 10°C) and the cell pellet was resuspended in 50 ?L PBS and 200 ?L RNAlater (Ambion, Austin, TX). The epithelial cells acquired consisted primarily of transitional epithelium with some respiratory epithelium., Harvest Time Point: 5, Units of Harvest Time Point: days nasal epithelium, formaldehyde inhalation exposure, 0.7 ppm, 6 hours per day, 5 days per week, 5 day time point
