hTERT and cdk-4 immortalized human bronchial epithelial cell line
(source: central lung bronchiole)

The cells are characterized by unlimited growth while maintaining expression of cell type specific markers and functions such as:

  • Typical epithelial, cobblestone morphology
  • Expression of the stem cell marker p63
  • Expression of morphological features and markers of clara cells (clara cell specific protein CCSP, surfactant proteins SP-A, SP-D) as well as Type I and II pneumocytes (aquaporin 5, SP-A, SP-C, SP-D) upon 2D differentiation
  • Distinct response to microenvironment

Therefore, these cells are the only solution for gene editing using e.g. the CRISPR/Cas9 system when primary like characteristics are of importance. Additionally, isogenic cell lines that overexpress certain oncogenes or tumor suppressor genes are available as tumor progression model.
