hTERT immortalized human mammary epithelial cell line 
(source: mammary epithelium)

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

  • Epithelial morphology and adherent growth
  • Expression of the typical marker protein for mucosal surfaces mucin-1
  • Expression of luminal specific cytokeratins KRT8/18

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.
