Definition

Noun: - A scientific technique in genetics and cloning: "Somatic cell nuclear transfer" refers to the laboratory process of removing the nucleus from a somatic cell (any cell of the body except sperm or egg cells) and transferring it into an egg cell (oocyte) whose own nucleus has been removed. This creates a reconstructed cell that can develop into an organism genetically identical to the donor of the somatic cell nucleus.

Usage
  • This term is used primarily in scientific, medical, and bioethical contexts to describe the core method used in reproductive and therapeutic cloning.
  • It is often abbreviated as SCNT.
Examples
  • Noun:
    • Somatic cell nuclear transfer was the technique used to create Dolly the sheep, the first cloned mammal.
    • Research into somatic cell nuclear transfer aims to understand development and create patient-specific stem cells.
Advanced Usage
  • "Therapeutic somatic cell nuclear transfer": Refers to using SCNT to create embryonic stem cells for research and potential medical treatments, not to create a cloned organism.
    • The goal of therapeutic somatic cell nuclear transfer is to generate stem cells that can repair damaged tissues without risk of immune rejection.
Variants and Related Words
  • Nuclear transfer (n): A broader term for moving a nucleus from one cell to another; SCNT is a specific type.
  • Cloning (n): The general process of producing a genetically identical copy; SCNT is a key method for cloning.
  • Reprogramming (n): The process triggered by SCNT where the somatic cell nucleus is reset to an embryonic state.
Synonyms
  • Nuclear transplantation: A synonymous scientific term for the same procedure.
  • Therapeutic cloning: When SCNT is specifically used for creating stem cells for therapy.
Related Phrases
  • "Perform somatic cell nuclear transfer": To carry out the laboratory procedure.
    • The team aims to perform somatic cell nuclear transfer to study genetic diseases.
  • "SCNT-derived": Created or obtained through the SCNT process.
    • SCNT-derived stem cells hold great promise for regenerative medicine.
Noun
  1. moving a cell nucleus and its genetic material from one cell to another
