hTERT immortalized human foreskin fibroblast cell line

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

  • Typical fibroblastoid morphology 
  • Expression of typical mesenchymal marker vimentin 
  • Response to TGFß treatment by induction of α-SMA expression 
  • Response to IL17a treatment by induction of IL6 expression 
  • Response to IL1ß treatment by induction of IL6 and VEGF expression 

Therefore, these cells are the only solution for gene editing using e.g. the CRISPR/Cas9 system when primary like characteristics are of importance.

Assay for testing substances targeting TGFß as essential mediator of fibrosis.

Treatment of human hTERT immortalized fibroblasts with TGFß induces a concentration dependent increase in α-smooth muscle actin expression. The cellular response is measured using a novel immunofluorescence protocol that allows measurement in 96-well plate format.

Assay for testing the inhibition of IL17a induced IL6 secretion
Treatment of human hTERT immortalized fibroblasts with IL17a induces a concentration dependent increase in IL6 secretion, which is recorded using a standardized ELISA protocol.
