hTERT immortalized human renal proximal tubular epithelial cell line

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

  • Typical epithelial, cobblestone morphology
  • Functional tight junctions as evidenced by ZO-1 expression, dome formation and trans epithelial electrical resistance (TEER) levels like normal cells
  • Gamma glutamyl-transferase activity
  • Expression of Aminopetidase-N and E-cadherin
  • Response to parathyroid hormone (PHT) treatment by increased cAMP production
  • Transporter activity when differentiated (MRP2, MRP4, OAT4, MDR1, MATE1, OCTN2, OCT3)

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

Furthermore, in collaboration with The Human Protein Atlas next generation sequencing was performed and data are available for download to support your decision process in selecting cells that are fit for purpose - get these data after log in from our database below.
