Retrovirus and lentivirus vectors enable stable gene transfer into embryonic stem cells for genetic gain or loss of function studies. This technology aids in analyzing gene roles and selecting cell lineages in research.

Area of Science:

  • Biomedical research
  • Genetic engineering
  • Stem cell biology

Background:

  • Significant advancements in genetic engineering technologies over 30 years.
  • Embryonic stem cells (ESCs) are increasingly central to genetic manipulation strategies.
  • Established methods for transgene expression and gene loss-of-function analysis.

Purpose of the Study:

  • To describe the application of retrovirus/lentivirus vectors for gene transfer in ESCs.
  • To enable genetic gain-of-function and loss-of-function analyses in ESCs.
  • To facilitate cell lineage selection in experimental settings.

Main Methods:

  • Utilizing retrovirus/lentivirus vectors for gene delivery.
  • Stable gene expression and integration in mouse and human ESCs.
