Clonogenic cell survival assay.

Area of Science:

• Cell Biology
• Radiobiology
• Pharmacology

Background:

• The clonogenic cell survival assay assesses indefinite cell proliferation and reproductive ability.
• Cell survival curves illustrate the relationship between insult dose and surviving cell fraction.
• Initially vital in radiobiology, these assays now evaluate various clinical agents.

Purpose of the Study:

• To detail the methodology for establishing a clonogenic cell survival assay.
• To provide a framework for evaluating cellular reproductive integrity.
• To highlight the assay's broad applicability in preclinical and clinical research.

Main Methods:

• Utilizing established cell lines (human or rodent, neoplastic or normal) in culture.
• Exposing cells to various agents, including ionizing radiation and chemotherapeutics (e.g., etoposide, cisplatin).
• Quantifying the fraction of cells capable of forming colonies post-treatment to generate survival curves.

Main Results:

• Demonstrated the generation of cell survival curves for diverse cell lines.
• Established the assay's utility in assessing the effects of radiation and various clinical agents.
• Provided a reproducible experimental protocol for clonogenic assays.

Conclusions:

• Clonogenic cell survival assays are fundamental for evaluating cell reproductive integrity.
• The assay's versatility extends to radiobiology, chemotherapy, and targeted therapy research.
• This protocol facilitates the application of clonogenic assays in diverse research settings.
