Definition
Noun: 1. Therapeutic Cloning: A specific type of cloning, also known as therapeutic cloning or somatic cell nuclear transfer (SCNT), where the nucleus from a patient's own somatic (body) cell is transplanted into an enucleated egg cell (oocyte). The purpose is not to create a cloned organism, but to derive genetically compatible cells, particularly stem cells, for potential therapeutic transplantation back into the patient.
Usage
- Biomedical cloning is a promising field of research aimed at generating patient-specific tissues for regenerative medicine.
- The primary goal of biomedical cloning is to produce embryonic stem cells that are a genetic match to the donor, thereby avoiding issues of immune rejection.
- Ethical debates often distinguish biomedical cloning from reproductive cloning, as the former is intended for therapy, not for creating a new individual.
Advanced Usage
- The term is often used in scientific and bioethical contexts to specify the of the cloning procedure, contrasting it with reproductive cloning.
- It is frequently discussed in relation to potential treatments for diseases like Parkinson's, diabetes, and spinal cord injuries.
Variants and Related Words
- Therapeutic Cloning: A direct synonym for biomedical cloning.
- Somatic Cell Nuclear Transfer (SCNT): The technical name for the procedure used in biomedical cloning.
- Reproductive Cloning: A related but distinct process where the cloned embryo is implanted into a uterus to produce a cloned organism. This is the goal of biomedical cloning.
Synonyms
- Therapeutic Cloning
- Somatic Cell Nuclear Transfer (SCNT) (refers to the technique itself)

Noun
