Here’s a look at cloning, a process of creating an identical copy of an original. Facts Reproductive Cloning is the process of making a full living copy of an organism. Reproductive cloning of animals transplants nuclei from body cells into eggs that have had their nucleus removed. That egg is then stimulated to divide using an electrical charge and is implanted into the uterus of a female. Therapeutic Cloning is the process where nuclear transplantation of a patient’s own cells makes an oocyte from which immune-compatible cells (especially stem cells) can be derived for transplant. These cells are stimulated to divide and are grown in a Petri dish rather than in the uterus. Gene Cloning creates copies of genes or DNA fragments. Gene cloning is the most common form of cloning performed by researchers at the National Human Genome Research Institute. Genes are cloned for scientists to study in a laboratory setting.

September 2011 - At South Korea’s Incheon Airport, seven “super clone” sniffer-dogs are dispatched to detect contraband luggage. They are all golden Labrador Retrievers that are genetically identical to Chase, who was the top drug detention canine until he retired in 2007. May 15, 2013 - Oregon Health & Science University researchers report in the journal Cell that they have successfully reprogrammed human skin cells back to their embryonic state. April 2014 - For the first time, cloning technologies are used to generate stem cells that are genetically matched to adult patients. Scientists put the nucleus of an adult skin cell inside an egg and the reconstructed egg went through the initial stages of embryonic development, according to research published in the journal Cell Stem Cell. January 24, 2018 - For the first time, scientists say they created cloned primates using the same complicated cloning technique that made Dolly the sheep in 1996. Shanghai scientists created two genetically identical long-tailed macaques. The research is published in the journal Cell. February 18, 2021 - Scientists announce that for the first time, they have cloned an endangered US animal, creating a black-footed ferret named Elizabeth Ann from the frozen cells of an ancestor in a landmark achievement that boosts conservation efforts. March 17, 2021 - Scientists announce in the journal Nature that they have generated a model of an early human embryo, called iBlastoids, by reprogramming skin cells. Researchers imagine its usage to include aiding with in vitro fertilization therapies and the study of early human development. The model cannot develop into a human being.

TruthLens AI Summary
Cloning is a scientific process that involves creating an identical copy of an organism, and it can be categorized into three main types: reproductive cloning, therapeutic cloning, and gene cloning. Reproductive cloning aims to produce a complete living organism by transferring the nucleus from a body cell into an egg cell from which the nucleus has been removed. This egg is then stimulated to divide and is implanted into a surrogate uterus. Therapeutic cloning, on the other hand, focuses on generating stem cells that are compatible with a patient’s immune system. In this process, the nucleus of a patient’s cells is transplanted into an egg, leading to the development of stem cells in a laboratory setting. Gene cloning is the most prevalent form of cloning used in research, enabling scientists to create multiple copies of specific genes or DNA fragments for study and experimentation. This technique is essential in understanding genetic functions and disease mechanisms at the molecular level.
The history of cloning is marked by significant milestones that showcase its evolution over the decades. In 1952, researchers successfully demonstrated the ability to remove a nucleus from a frog's egg and replace it with an embryonic cell nucleus, leading to the development of a tadpole. The landmark achievement of cloning a mammal occurred in 1997 with the announcement of Dolly the sheep, who was cloned from adult cells. Since then, various species have been cloned, including mice, pigs, and even dogs, with notable advancements such as the creation of the first cloned horse and the cloning of endangered species like the black-footed ferret. Cloning technology has also been utilized in stem cell research, with advancements reported in creating stem cells that are genetically matched to adults. Despite controversies, particularly surrounding claims of human cloning, the scientific community continues to explore cloning's potential applications in medicine and conservation, demonstrating its profound implications for the future of biology and healthcare.
