What Is A Clone – One of the most enjoyable parts of running a site like The Niche is that readers’ questions can sometimes be eye-opening including new ones about human cloning.
Human cloning: two main types. Note that other types of activation besides shock as well as cell fusion methods can be used for the step shown in the middle.
What Is A Clone
Some readers recently asked whether human cloning could be used on some level to bring back the dead version.

Losing a loved one can be a devastating shock and a lot to deal with in the months and years to come. I can understand why some people might think of cloning as a possible option.
The clone will not be the same person that was lost. They will be like identical twins produced at different times.
The uterine environment can also have a major effect. If it is a dead child and then the same mother carries the child’s clone to term, the womb environment can be the same as when the first daughter or son was born. However, a few years will pass, so the health, diet, external environment, etc. from the mother may be different.
Another thing to think about is that the clones will be babies first so they don’t look the same as the dead until the clones reach the same age. However, parents may have memories of what their child looked like as a baby and the clone will probably look almost the same.
If You Lost A Loved One, Could You Turn To Human Cloning?

I have written about cloning several times, so check it out for background. See also my latest article: Human cloning is easier now but will you take a big risk?
The danger may include developmental disorders facing clones or even death after birth. I also think that research on human reproductive cloning will lead to a large number of abortions along the way.
Practically speaking, even to start configuring humans, you need healthy living cells from them. If someone has died, it is not always possible to obtain and preserve such cells. In the intensity of grief it is also possible that saving cells may not come to mind.
Genes & Society: Cloning
Technologies that could advance human cloning used for reproduction have advanced over the 12 years I’ve been writing The Niche.
Animal cloning has also made an important step forward as a technology that can enable experiments on the human version.
All this raises other important considerations. Even cloning driven by an understandable desire to replace a lost loved one can enable more dubious or even unethical use of the same technology by others.
For example, if human cloning technology research is advanced for a specific business focused on producing a clone of a missing family member, others can then use the technology to create clones for unethical reasons.

There may even be reckless cloning such as a dead celebrity or an attempt to bring back an icon (for example see Imagine Cloning John Lennon from Old Molar and Justin Beiber or Einstein or you? Who got the first clone?)
As an update, note that there is a myth floating around that covid tests will be used to clone people, which is complete nonsense. Reproductive cloning involves the implantation of a cloned embryo into a real or artificial womb. The embryo grows into a fetus which is then brought to term. Reproductive cloning experiments have been carried out for more than 40 years through the process of embryo splitting, in which an initial two-cell embryo is manually divided into two individual cells and then grows into two identical embryos. Reproductive cloning techniques underwent a significant change in the 1990s, after the birth of Dolly, who was produced through the SCNT process. This process involves removing the entire nucleus from the somatic cell (body) of an organism, followed by the insertion of the nucleus into the egg cell that has had its own nucleus removed (enucleation). Once the somatic nucleus is inside the egg, the egg is stimulated by a mild electric current and begins to divide. Thus, a cloned embryo, basically an identical twin embryo of the original organism, is created. The SCNT process has undergone significant improvements since the 1990s, and procedures have been developed to prevent egg damage during nuclear extraction and nuclear insertion of somatic cells. For example, the use of polarized light to visualize the nucleus of the egg cell facilitates the extraction of the nucleus from the egg, resulting in healthy, viable eggs thus increasing the success rate of SCNT.
Reproductive cloning using SCNT is considered very dangerous because fetuses from embryos cloned through SCNT rarely survive pregnancy and are usually born with birth defects. Wilmut’s team of scientists needed 277 attempts to create Dolly. Similarly, an attempt to produce a macaque clone in 2007 involved 100 cloned embryos, implanted into 50 female macaque monkeys, none of which resulted in viable pregnancies. In January 2008, scientists at Stemagen, a stem cell research and development company in California, announced that they had cloned five human embryos using SCNT and that the embryos had matured to the stage where they could be implanted in the uterus. However, the scientists destroyed the embryos after five days, in order to carry out molecular analysis.
Therapeutic cloning is intended to use cloned embryos to extract stem cells from them, without ever implanting the embryo in the uterus. Therapeutic cloning enables the cultivation of stem cells that are genetically identical to the patient. Stem cells can be stimulated to differentiate into any of the more than 200 cell types in the human body. The differentiated cells can then be transplanted into patients to replace diseased or damaged cells without the risk of rejection by the immune system. These cells can be used to treat a variety of conditions, including Alzheimer’s disease, Parkinson’s disease, diabetes mellitus, stroke and spinal cord injury. In addition, stem cells can be used for in vitro (laboratory) studies of normal and abnormal embryo development or to test drugs to see if they are toxic or cause birth defects.
Healthy Cloned Offspring Derived From Freeze Dried Somatic Cells
Although stem cells have been derived from cloned embryos of animals such as mice, the generation of stem cells from cloned primate embryos has proven exceptionally difficult. For example, in 2007 stem cells derived from cloned macaque embryos were able to differentiate into adult heart cells and brain neurons. However, the experiment started with 304 egg cells and resulted in the development of only two stem cell lines, one of which had an abnormal Y chromosome. Likewise, the production of stem cells from human embryos has been fraught with the challenge of maintaining embryonic viability. In 2001, scientists at Advanced Cell Technology, a research firm in Massachusetts, succeeded in transferring DNA from human cumulus cells, which are cells that attach and nourish human eggs, to eight nucleated eggs. Of these eight eggs, three developed into early stage embryos (containing four to six cells); however, embryos survive only long enough to divide once or twice. In 2004, South Korean researcher Hwang Woo Suk claimed to have cloned a human embryo using SCNT and extracted stem cells from the embryo. However, this later turned out to be a fraud; Hwang made evidence and actually carried out the process of parthenogenesis, where an unfertilized egg begins to divide with only half the genome. The following year, a research team from the University of Newcastle-upon-Tyne was able to grow an embryo cloned to the 100-cell blastocyst stage using DNA from embryonic stem cells, although they did not produce a stem cell line from the blastocyst. Scientists have since successfully derived embryonic stem cells from SCNT human embryos.
Progress in research on therapeutic cloning in humans has been slow compared to the progress made in animal reproductive cloning. This is mainly due to technical challenges and ethical conflicts arising from the acquisition of human eggs solely for research purposes. In addition, the development of induced pluripotent stem cells, which are derived from somatic cells that have been reprogrammed to the embryonic state by the introduction of specific genetic factors into the cell nucleus, challenging the use of cloning methods and human eggs. : special cells found in your reproductive organs that have half the amount of DNA of somatic cells. These cells join together to make a fertilized egg…again
Dolly is the name of a sheep that has the honor of being the first mammal to be cloned by a group of scientists in Scotland. Dolly was born on July 5, 1996 and died in 2003. She lived for 6 and a half years, as a normal active sheep. He’s not normal though, he’s also a clone.
There are several breeds of sheep
