Area of Science:

  • Genetics and Genomics
  • Molecular Biology
  • Developmental Biology

Background:

  • Gene function is often studied using animal models.
  • Understanding gene products requires analyzing their roles within a complete organism.
  • The mouse is a key model organism in genetic research.

Purpose of the Study:

  • To describe the established gene-targeting technology in mice.
  • To highlight its utility in functional genomics.
  • To outline the process for generating genetically modified mouse models.

Main Methods:

  • Designing and constructing targeting vectors for gene modification.
  • Transfecting embryonic stem cells and selecting for homologous recombination.
  • Generating chimeric mice via blastocyst injection and foster mother transfer.
  • Breeding chimeras to obtain heterozygous and homozygous mutant mice.

Main Results:

  • Successful generation of mice with targeted gene alterations.
  • Demonstration of gene-targeting as a robust method for functional gene analysis.
  • Production of specific mutant mouse lines for research.

Conclusions:

  • Gene-targeting technology is a powerful tool for dissecting gene function in vivo.
  • This method facilitates the creation of precise genetic models for disease and biological research.
  • The described process enables the systematic study of gene products in the context of a whole animal.
