SRP313527 PRJNA719801 GSE171488 Single-cell RNA sequencing of human nasal swab from healthy donors Understanding on pathogenesis of COVID-19 is rapidly growing, but primary target cells of SARS-CoV-2 infection is still not known. Here, we performed single cell RNA sequencing on human nasal swab from healthy donors to investigate the expression patterns of host cell entry factors of SARS-CoV-2. Overall design: Single cells from healthy donors' nasal swabs were isolated and single-cell transcriptome libraries were generated GSE171488 pubmed 34003804
