Somatic cell nuclear transfer

She was born in 1996 in Scotland as part of some experiments at The Roslin Institute. Dolly was “made” from a cell that was taken from the udder of her biological mother, which was then inserted into a sheep ovum and manipulated to create an embryo (Jesper Lassen, 2006). After that, the embryo was placed into a foster mother who carried Dolly until birth. Dolly…

American Medical Association defines cloning as “the production of genetically identical organisms via somatic cell nuclear transfer” (“Human Cloning”, 2013). Cloning is basically a method used to produce a baby that has identical genes to its parents (Dixon, 2008). It is done by taking an egg cell and removing the nucleus, which contains the required DNA (Dixon, 2008). Then DNA is taken from an adult cell and is inserted into the nucleus (Dixon, 2008). The reconstructed egg is then stimulated…

The Importance of the Stem Cell CJ Kemper Stem cell research on adult and embryonic stem cells has the potential to develop cures for diseases that kill millions of people all over the world. First off, stem cells are the unspecialized cells from which differentiated cells develop(Miller et Levine). In the early 1900’s, attempts were made to fertilize mammalian eggs outside of the human body. It was then discovered that some cells were able to generate blood cells. In 1968, the very first bone…

STEM CELL AND CLONING, Application and ETHICS INTRODUCTION: In today’s ever-evolving world of science and technology, we should always ask the question as to how far are we willing to go in terms of stem cell research and cloning. Do people believe in the concept of cloning human cells or will there forever be a line that can never be crossed? Stem cell research offers great promise for understanding of basic mechanisms of human development and differentiation. It is vital in new treatments for…

Jenkins Lesley Willoughby Gripped in controversy, the United States of America had grappled with whether or not to study embryonic stem cells and clone human tissues since they were discovered. Stem cells, according to the National Institutes of Health, are unspecialized cells with remarkable potential for developing into a variety of organic structures (Stem Cell Basics: Introduction). These biological components were first discovered in human umbilical cord blood in 1978, and in 1981, they…

disorders e.g. heart disease, cancer, obesity, down syndrome etc. and these abnormalities can vary from minor mutation to major mutation. The genetic disorders are due to different types of genetic inheritance; 1. Single gene inheritance (e.g. sickle cell anemia) 2. multifactorial inheritance (e.g. diabetes, high blood pressure) 3. Chromosome abnormalities (e.g. Turner syndrome) 4. Mitochondrial inheritance (e.g. mitochondrialenchepalopathy) [7]. These cases are the direct result of a mutation…

Depending on the purpose for the cloning procedure, human health or reproduction can result in an evolutionary change. “Somatic cell nuclear transfer (SCNT) is the most common cloning technique. SCNT involves putting the nucleus of a body cell into an egg from which the nucleus has been removed."^1 (Center for Genetics, 1) From this technique, reproductive cloning enables an embryonic cell to produce an animal that is genetically identical to the donor. Today, human cloning still remains as a…

has a 50-50 chance of blowing up” (Choi 1), says Robert Lanza on cloning. Cloning is one of the more risky ways to reproduce and has mostly negative results. Although not always successful, the most common method of cloning is called Somatic Cell Nuclear Transfer. During this process, the genetic material from an egg of the first test subject is removed. The genetic material from the subject that wishes to be cloned will be injected into that egg and then implanted into the second organism.…

Cloning is a process by which identical cells are produced from preexisting cells. The two current types of human cloning come in the form of human reproductive cloning and human therapeutic cloning. As with any new technology, both present unique benefits and potential detriments. On July 5th, 1996, Dolly, the first ever cloned sheep, was born through a reproductive cloning method known as somatic cell nuclear transfer or SCNT (Vos). SCNT involves taking an ovum that has had its nucleus removed…

Social and legal implications: Embryonic and fetal stem cells are both heavily contested topics as the thought of destroying human life at any stage has always been a topic of debate by a large faction of the nation. It is usually religious beliefs people are affiliated with, that drive them to advocate for the end of stem cell research. The Supreme Court was of no help or harm in this matter as the philosophical ruling that all life is sacred or that life starts at conception is admittedly a…
