Summary
Mammal cloning efficiency improves with specific stem cell types. Research suggests using pluripotent or totipotent stem cells and epigenetic modulators to enhance somatic cell nuclear transfer success.
Area of Science:
- Reproductive biology
- Stem cell science
- Genetics
Background:
- Somatic cell nuclear transfer (SCNT) is a standard technique for mammalian cloning.
- Current cloning efficiency is limited, particularly with differentiated donor cells.
- Adult multipotent stem cells show promise, but embryonic stem cells are largely restricted to mice.
Purpose of the Study:
- To explore strategies for improving mammalian cloning efficiency.
- To investigate the potential of different stem cell types in cloning.
- To understand the role of epigenetic modifications in cloning success.
Main Methods:
- Review of existing literature on mammalian cloning techniques.
- Analysis of the correlation between donor cell differentiation and cloning efficiency.
- Evaluation of stem cell potential (multipotent, pluripotent, totipotent) in cloning.
Main Results:
- Cloning efficiency is inversely related to donor cell differentiation.
- Adult multipotent stem cells can enhance cloning outcomes.
- Embryonic stem cells offer greater cloning potential, demonstrated primarily in mice.
Conclusions:
- Deriving pluripotent or totipotent stem cells from diverse species is key.
- Modulating epigenetic marks in donor cells is crucial for increased cloning efficiency.
- Future research should focus on livestock and wild species stem cell derivation and epigenetic reprogramming.

Introduction to Nuclear Reprogramming
2.0K
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...

Reproductive Cloning
30.6K
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).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...

Methods of Nuclear Reprogramming
1.9K
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...

Cloning of Dolly the Sheep
4.1K
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...

Embryonic Stem Cells
3.6K
Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Induced Pluripotent Stem Cells
4.2K
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
