Cell-intrinsic differences between human airway epithelial cells from children and adults 2020-04-20 .txt text/plain 8186 419 47 Here, we perform bulk RNA sequencing studies in laser-capture microdissected whole epithelium, FACS-sorted basal cells and cultured basal cells, as well as in vitro cell proliferation experiments, to address the intrinsic molecular differences between paediatric and adult airway basal cells. We found no significant differences in the proportion of cells in these three cellular compartments in paediatric and adult biopsies either by immunohistochemistry ( Figure 1A /1B), or by assessing basal, mucosecretory or ciliated cellassociated gene expression (Table S2 ) in bulk RNA sequencing in which we had laser-capture microdissected the whole epithelium ( Figure 1C ; Figure S1 ). Analysing this laser-capture microdissected whole epithelium RNA sequencing dataset using DESeq2 (Love et al., 2014) with a false discovery rate (FDR) of 1% and log2 fold change threshold of 1.2, we identified 37 genes with significant differential expression between paediatric and adult donors of which 17 were upregulated in adults and 20 were expressed at higher levels in children ( Figure 2A ; Table S3 ). ./cache/cord-103914-ppgx7mci.txt ./txt/cord-103914-ppgx7mci.txt
