The Application of hTERT-immortalized Primary Cells in Toxicological Assays

May 23, 2019, at 12:00 PM ET


Developing cell-based assays can be problematic; the cells must be physiologically relevant for the assay to be predictive, yet sufficiently abundant to be included in the assay without introducing interexperimental variability. hTERT-immortalized primary cells address both issues. hTERT-immortalized primary cells exhibit the growth characteristics of continuous cell lines while providing the physiological attributes of primary cells. In this presentation, ATCC experts will discuss the characteristics of hTERT-immortalized primary cells derived from the kidney, skin, airway, and vasculature and will describe the versatility of these cells in toxicological assays.

Key Points

  • hTERT-immortalized primary cells are comparable to primary cells regarding physiological relevance, but without the limitation of proliferation.
  • Using well-characterized hTERT-immortalized cells, ATCC has created credible cell models for toxicological studies on the kidney, skin, airway, and vasculature.
  • Our data show that these modified cell lines are effective tools that provide tissue-relevant results and reproducibility for any cell-based assay, including toxicology assays.
