Area of Science:

  • Biomarkers and Molecular Epidemiology
  • Genotoxicity and Cellular Health Assessment

Background:

  • The Buccal Micronucleus Cytome (BMCyt) assay is an emerging tool for evaluating DNA damage and cellular processes in buccal mucosal tissue.
  • Its application is expanding in molecular epidemiology to investigate environmental and genetic factors influencing DNA damage and cell death.

Purpose of the Study:

  • To detail the established protocols for the Buccal Micronucleus Cytome (BMCyt) assay.
  • To provide guidelines for buccal cell collection, slide preparation, staining, and scoring.

Main Methods:

  • Describes standardized procedures for buccal cell collection.
  • Outlines techniques for cellular and nuclear staining.
  • Defines scoring criteria for cytome analysis.

Main Results:

  • Biomarkers from the BMCyt assay are linked to increased risks of accelerated aging, cancer, and neurodegenerative diseases.
  • The assay provides insights into DNA damage, chromosomal instability, cell death, and tissue regeneration.

Conclusions:

  • The BMCyt assay is a valuable, minimally invasive method for studying DNA damage and cellular health.
  • Established protocols ensure reliable data for epidemiological and clinical research.
