What is the best way to clone mice?
We have developed a technique for cloning the laboratory mouse by transferring cumulus cell nuclei into enucleated oocytes. With this technique, we have produced a population of over 80 cloned animals, and have carried the process over four generations. Development and fertility of these appear normal.
Is it possible to clone mammals?
A brief account is given of early attempts to clone mammals (mice) by transferring cells (nuclei) of preimplantation embryos into enucleated oocytes, zygotes or blastomeres of two-cell embryos. This is followed by a brief review of recent successes using adult somatic cells: mammary gland cells for …

What are the steps to cloning a mouse?
Using the "Mouse Cloning Lab," users practice cloning by going through the steps of isolating donor cells from mice, removing and discarding the nucleus from an egg cell, transferring a somatic cell nucleus into an enucleated egg cell, stimulating cell division, implanting an embryo and delivering the clone of a baby ...
Can you clone a mouse?
Researchers in Japan have for the first time cloned mice using single white blood cells from peripheral blood samples. The advance could mean the ability to clone infertile mice from which healthy eggs or sperm cannot be obtained. The results were published online Wednesday (June 26) in Biology of Reproduction.
What is mouse cloning?

With this technique, we have produced a population of over 80 cloned animals, and have carried the process over four generations. Development and fertility of these appear normal.
How was Cumulina the mouse cloned?
In 1998, Wakayama et al used Honolulu method to inject enucleated oocytes with cumulus cell nuclei and produced the first cloned mouse, Cumulina, which survived (6). They removed the nucleus from a somatic cell and injected it into an oocyte with removed nucleus.
Can blood be used for cloning?
Scientists in Japan have cloned a mouse from a single drop of blood. Circulating blood cells collected from the tail of a donor mouse were used to produce the clone, a team at the Riken BioResource Center reports in the journal Biology of Reproduction.
Can you clone animals with blood?
Scientists in Japan have been able, for the first time, to successfully clone a mouse from a blood sample drawn from a living donor's tail. Scientists at the Riken BioResource Center in Japan have managed to clone a mouse from a minuscule, peripheral blood sample for the first time.
Is human cloning?
Have humans been cloned? Despite several highly publicized claims, human cloning still appears to be fiction. There currently is no solid scientific evidence that anyone has cloned human embryos.
What color will the cloned mouse be?
brownThe Mouse Pup will resemble the Somatic Cell Donor, since this Donor provided the DNA for the cloned egg. The Mouse Pup will be brown (and female) like the Somatic Cell Donor. 1.
How was Mira the goat cloned?
Mira and her sisters were made using a variation on the nuclear transfer technique that produced Dolly the Sheep, the first mammal cloned from an adult cell. In this case, the researchers took genetic material from a 40-day-old goat embryo which carried the transgene that expressed rhAT III.
Can males be cloned?
The female monopoly on mammalian reproduction has been challenged. Teruhiko Wakayama and Ryuzo Yanagimachi of the University of Hawaii School of Medicine, Honolulu, Hawaii have successfully cloned the first male animal - a mouse, named Fibro.
Who cloned the first mouse?
Ryuzo YanagimachiCumulina (October 3, 1997-May 5, 2000), a mouse, was the first animal cloned from adult cells that survived to adulthood. She was cloned using the Honolulu technique developed by "Team Yana", the Ryuzo Yanagimachi research group at the former campus of the John A.
What are the pros of cloning?
Pros of CloningIt can help prevent the extinction of species. As many organisms in the planet approach endangerment and extinction, cloning appears to be a possible solution to restore populations. ... It can help increase food production. ... It can help couples who want to have children.
What color will the cloned mouse be?
brownThe Mouse Pup will resemble the Somatic Cell Donor, since this Donor provided the DNA for the cloned egg. The Mouse Pup will be brown (and female) like the Somatic Cell Donor. 1.
When was the first mouse cloned?
1997The Smithsonian's National Museum of American History has acquired the taxidermy remains of Cumulina, the first mouse cloned from an adult somatic (non-reproductive) cell by reproductive biologists Ryuzo Yanagimachi and Teruhiko Wakayama at the University of Hawai'i in 1997.
Can they clone animals?
Cloning is a complex process that lets one exactly copy the genetic, or inherited, traits of an animal (the donor). Livestock species that scientists have successfully cloned are cattle, swine, sheep, and goats. Scientists have also cloned mice, rats, rabbits, cats, mules, horses and one dog.
How old was Dolly the sheep when she died?
6-year-oldDolly the sheep, the first mammal cloned from an adult cell, died on 14 February. Her caretakers at the Roslin Institute in Scotland euthanized the 6-year-old sheep after diagnosing an incurable lung tumor.
Abstract
The mouse is the most extensively used mammalian laboratory species in biology and medicine because of the ready availability of a wide variety of defined genetic and gene-modified strains and abundant genetic information. Its small size and rapid generation turnover are also advantages compared with other experimental animals.

What is the best way to fertilize a mouse?
If at least one of the remaining mice is male and possesses healthy germ cells, the best option is intracytoplasmic sperm injection (ICSI), an in vitro fertilization procedure in which a single sperm is injected directly into an egg.
Why are genetically modified mice used in research?
From obesity to substance abuse, from anxiety to cancer, genetically modified mice are used extensively in research as models of human disease. Researchers often spend years developing a strain of mouse with the exact genetic mutations necessary to model a particular human disorder. But what if that mouse, due to the mutations themselves or a simple twist of fate, was infertile?
How many species of sheep have been cloned?
Since Dolly the sheep in 1996, reproductive cloning has continued to advance; nearly 20 different mammalian species have now been cloned. Researchers have now developed a unique cloning procedure using peripheral blood cells, which may be collected repeatedly from a single animal and so facilitate preservation of infertile mouse strains.
Can mice produce germ cells?
However, if the remaining mice cannot produce healthy germ cells, or if they are female, researchers must turn to cloning. Somatic-cell nuclear transfer (SCNT) produces cloned animals by replacing an oocyte's nucleus with that of an adult somatic cell. An early version of this process was used to produce Dolly the sheep in 1996.
Can mice be cloned?
Although the blood cells tested did not surpass the success rate of cumulus cells in this study, the researchers have demonstrated, for the first time, that mice can be cloned using the nuclei of peripheral blood cells. These cells may be used for cloning immediately after collection with minimal risk to the donor, helping to generate genetic copies of mouse strains that cannot be preserved by other assisted reproduction techniques.
