Other markers for airway epithelial cells that are expressed through ALIw5 include the cell surface‐associated mucin MUC4, the gel‐forming mucin MUC5B, and the basal cell progenitor marker tumour protein p63 (TP63) (see GEO GSE136859, CompletePath_Counts.csv). This evidence concerns the gene MUC5B and neoplasm.
