Isolation and Characterization of Lymphocytes from Human Mucosal Biopsies.
Methods in molecular biology (Clifton, N.J.)(2019)
摘要
The important role of the local mucosal environment in both the initiation and progression of allergic disease is well established. Analysis of tissue-resident lymphocyte subsets by flow cytometry requires isolation of viable cells from mucosal samples.Here we describe an advanced method to dissociate lymphocytes from human mucosal (e.g., nasal, bronchial) biopsies. Single-cell suspensions are obtained through a combination of gentle mechanical disruption and incubation of tissue with proteolytic enzymes. This method fully utilizes limited clinical samples and is amenable to a variety of downstream applications for phenotypic, single-cell analysis of tissue lymphocytes or pooled lymphocyte subsets.
