Cell-based systems enhance drug discovery by complementing in vitro assays. This review explores technologies for creating robust cell lines for high-throughput screening (HTS) and drug development.

Area of Science:

  • Biotechnology
  • Cell Biology
  • Drug Discovery

Background:

  • Recombinant proteins are standard for in vitro high-throughput screening (HTS), but lack biological complexity.
  • Cell-based systems offer greater confidence in compound activity within an intact biological context.
  • Primary cells and stem cells present challenges for HTS, leading to the use of immortalized cell lines.

Purpose of the Study:

  • To review technologies for generating cell lines suitable for in vitro biology and drug discovery.
  • To discuss the advantages and limitations of various cell line generation strategies.
  • To present a range of cell lines utilized in current drug discovery pipelines.

Main Methods:

  • Exploration of molecular strategies for overcoming cellular senescence and telomere shortening.

  • Discussion of viral oncogene expression and telomerase reverse transcriptase (TERT) for cell immortalization.
  • Analysis of conditional immortalization approaches to improve cell model suitability.

    • Main Results:

    • Immortalized cell lines, while proliferative, often exhibit genetic and functional aberrations.
    • Strategies like oncogene and TERT expression can induce persistent proliferation but may affect differentiation.
    • Conditional immortalization offers a more controlled approach for generating suitable cell models.

    Conclusions:

    • Cell-based assays are crucial for validating drug candidates identified through HTS.
    • Advanced cell line generation technologies are essential for creating reliable models in drug discovery.
    • The choice of cell line technology impacts the predictive power of drug screening assays.
