Summary
Somatic cell nuclear transfer is the primary method for cloning ruminants like sheep and cattle. This technique has advanced our understanding of cell reprogramming, benefiting stem cell research and medicine.
Area of Science:
- Reproductive Biology
- Developmental Biology
- Genetics
Background:
- Ruminants were the first mammals successfully cloned via nuclear transplantation, initially for agricultural purposes.
- Cloning research has significantly contributed to understanding somatic cell reprogramming, crucial for stem cell research and human medicine.
- While nuclear transfer techniques are largely consistent, species-specific adaptations are necessary.
Purpose of the Study:
- To detail the somatic cell nuclear transfer (SCNT) technique for ruminant cloning.
- To provide specific considerations for sheep and cattle cloning via SCNT.
Main Methods:
- Detailed description of somatic cell nuclear transfer (SCNT) procedures.
- Focus on micromanipulation techniques relevant to ruminant oocytes and somatic cells.
- Adaptation of protocols for species-specific requirements in sheep and cattle.
Main Results:
- Successful application of SCNT in ruminant species.
- Demonstration of SCNT as the foremost method for ruminant cloning.
- Insights into the reprogramming of somatic cells in cloned ruminants.
Conclusions:
- Somatic cell nuclear transfer remains the primary method for cloning ruminants.
- SCNT advancements have broad implications for developmental biology and regenerative medicine.
- Understanding species-specific technical needs is vital for successful ruminant cloning.

01:14Introduction to Nuclear Reprogramming
1.3K
Nuclear reprogramming is the process of switching gene expression of one cell type to that of another cell type, usually from a differentiated cell state to an undifferentiated cell state. Differentiation occurs during processes such as development and morphogenesis, tissue regeneration, and malignancy. Cells can also be artificially induced to reprogram their gene expression by techniques such as nuclear transfer, induced pluripotency, and cell fusion. Such techniques have many applications in...

8.5K
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...

01:24Methods of Nuclear Reprogramming
1.4K
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for...

03:20Nuclear Transmutation
12.9K
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed...

01:27Reproductive Cloning
28.4K
Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
