Programmed cell death (apoptosis) is vital for development and health. This review details methods for detecting apoptosis, crucial for understanding diseases like cancer and autoimmune disorders.

Area of Science:

  • Cell Biology
  • Biochemistry

Context:

  • Apoptosis, or programmed cell death, is a fundamental biological process essential for development and maintaining tissue balance.
  • Dysregulation of apoptosis is implicated in various diseases, including cancer, autoimmune disorders, and degenerative conditions.

Purpose:

  • To review and compare various techniques used for evaluating apoptosis.
  • To assess the sensitivity of different methods for both qualitative and quantitative analyses of apoptosis.

Summary:

  • Apoptosis involves characteristic cellular changes like cell shrinkage, cytoplasmic condensation, and nuclear fragmentation.
  • Morphological changes are observable via electron microscopy.
  • Chromatin cleavage, a key apoptotic event, can be detected using electrophoresis and flow cytometry with DNA-binding fluorochromes.
