General description16HBE14o- is a human bronchial epithelial cell line isolated from a 1-year old male heart-lung patient and immortalized with the origin-of-replication defective SV40 plasmid (pSVori-). The cell line retains characteristic features of normal differentiated bronchial epithelial cells including a cobblestone morphology, cytokeratin expression, the ability to form tight junctions, and directional ion transport (1). When grown with an air/liquid interface, cilia can be detected. In contrast to most other respiratory cell lines, 16HBE14o- expresses high levels of cystic fibrosis transmembrane conductance regulator (CFTR) mRNA and protein (1). Expression of CFTR is correlated to cAMP-dependent Cl- conductance in a variety of cells, including 16HE14o- epithelial cells.
Application16HBE14o- Human Bronchial Epithelial Cell Line has been used in the expression of circular RNAs (circRNAs).
It has also been used in lipidomic analysis for comparison with cystic fibrosis cell line.
Biochem/physiol Actions
Epithelial Cells
Preparation Note
Store in liquid nitrogen. The cells can be cultured for at least 10 passages after initial thawing without significantly affecting the cell marker expression and functionality.
Analysis Note
• Each vial contains ≥ 1X106 viable cells.
• Cells are tested by PCR and are negative for HPV-16, HPV-18, Hepatitis A, C, and HIV-1 & 2 viruses as assessed by a Human Essential CLEAR panel by Charles River Animal Diagnostic Services.
• Cells are negative for mycoplasma contamination.
• Each lot of cells is genotyped by STR analysis to verify the unique identity of the cell line.
