Nuclear transfer (NT) enables the creation of embryos and offspring from various cell types. Successful development hinges on factors like cell source, reconstruction methods, and cell cycle synchronization.

Area of Science:

  • Reproductive biology
  • Developmental biology
  • Genetics

Background:

  • Nuclear transfer (NT) is a key biotechnological method for producing cloned animals.
  • The technique involves transferring a nucleus from a donor cell into an enucleated oocyte.
  • NT has applications in agriculture, conservation, and biomedical research.

Purpose of the Study:

  • To review the diverse applications of nuclear transfer technology.
  • To discuss the various techniques currently employed in NT.
  • To identify and analyze the critical factors influencing successful NT development.

Main Methods:

  • This review synthesizes existing literature on nuclear transfer.
  • It examines different donor cell types (embryonic, fetal, adult) and recipient oocytes.

  • Factors such as reconstruction, activation, and culture conditions are analyzed.

    • Main Results:

    • Nuclear transfer can generate embryos, fetuses, and offspring from various cell sources across species.
    • Developmental success is highly sensitive to numerous procedural and biological variables.
    • Optimization of recipient cell type, donor cell characteristics, and cell cycle matching is crucial.

    Conclusions:

    • Nuclear transfer is a versatile technique with broad applications in animal science.
    • Understanding and controlling the factors affecting NT is essential for improving efficiency and success rates.
    • Further research into optimizing NT protocols can enhance its utility in various fields.
