STAR Protocols (Jun 2022)
Isolation, cultivation, and application of primary respiratory epithelial cells obtained by nasal brushing, polyp samples, or lung explants
Abstract
Summary: Here, we present a standardized protocol for isolation, maintenance, and polarization of the respiratory epithelial primary cells from patient samples acquired from nasal brushing, polyp specimens, or lung explants. This protocol generates a clearly defined polarized layer of epithelial cells on filters, with a good number of ciliated cells and a thin layer of mucus. We detail the steps for samples prepared from patients with cystic fibrosis as well as from subjects without cystic fibrosis. : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
