Generating transgenic rats via DNA microinjection is established but challenging. This method offers valuable disease models and research applications, though germline-competent rat embryonic stem cells are still under development.

Area of Science:

  • Genetics and Genomics
  • Animal Models
  • Biotechnology

Background:

  • Transgenic rat production via DNA microinjection is an established technique.
  • Fewer than 20 transgenic rat lines have been reported in the past five years, indicating production challenges compared to mice.
  • Variations in methodology, including strain selection and embryo culture, exist across laboratories.

Purpose of the Study:

  • To review current methods for generating transgenic rats.
  • To highlight the utility of transgenic rats in disease modeling and research.
  • To discuss future perspectives, including the development of rat embryonic stem cells.

Main Methods:

  • DNA microinjection into fertilized rat ova.
  • Review of established protocols and variations in superovulation and embryo culture.

  • Analysis of data from existing transgenic rat models.

    • Main Results:

    • Satisfactory yields of transgenic rats have been achieved in multiple laboratories despite inherent difficulties.
    • Transgenic rats have yielded novel data distinct from transgenic mice.
    • Established models for hypertension, autoimmunity, carcinogenesis, and pharmacological research exist.

    Conclusions:

    • Transgenic rat technology is a valuable tool for biomedical research, offering unique advantages over mouse models.
    • Applications span disease modeling, drug discovery, and transplantation research.
    • Further development is needed for germline-competent rat embryonic stem cells for gene knockout studies.
