The difference with Dolly is that all her DNA originated in a cell from the udder of an adult sheep. (newscientist.com)
Dolly was the only lamb born from 277 fusions of oocytes with udder cells. (newscientist.com)
When the world learned in 1997 of Dolly the sheep, the first clone produced from an adult mammal, a broad public discussion about the ethics of human cloning ensued, largely focused on the nature, meaning, and future of human procreation. (thenewatlantis.com)

Should the parents of the child or teenager, or adults themselves take care of their own clone or would the clone be raised by some sort of company? (mystudywriters.com)
While stem-cell research holds enormous potential for treating or even curing some diseases, the cloning of a human being is morally and ethically unacceptable…Any attempt to clone a human being is in direct conflict with the public policies of this state. (cbc-network.org)
Claims that you could clone individual treatments of human beings to treat common diseases like diabetes, suggests you need a huge supply of human eggs. (wikiquote.org)

Many less controversial sources of acquiring stem cells include using cells from the umbilical cord, breast milk, and bone marrow, which are not pluripotent. (wikipedia.org)
Stem cells from umbilical cords are usually used only in children because umbilical cord blood does not contain enough stem cells to use in adults. (msdmanuals.com)
Stem cells can be obtained from the blood in the umbilical cord or placenta after a baby is born. (msdmanuals.com)

These cells are called totipotent stem cells . (orthodoxwiki.org)

The mature egg cell, observes Roger Gosden, a reproductive biologist at the University of Leeds in England, is the rarest cell in the human body. (discovermagazine.com)
Meanwhile, the ability of the mature egg to transform and begin embryonic development remains fully potent. (cbc-network.org)

In May 2007, Ontario and California announced a $30-million stem cell research deal aimed at finding new therapies for those diseases. (cbc.ca)
Future progress in this area holds promise for advancing islet- and beta cell-directed therapies that could be implemented in the early stages of the disease and could be combined with immunotherapies. (springer.com)

Donors must regularly undergo ultrasound and blood tests to monitor their developing oocytes. (discovermagazine.com)

In 1995 adult stem cell research with human use was patented (US PTO with effect from 1995). (wikipedia.org)

However, some evidence suggests that adult stem cell plasticity may exist, increasing the number of cell types a given adult stem cell can become. (wikipedia.org)

Adolescents, adults, and immunocompromised persons usually have more severe disease and are at higher risk for complications. (cdc.gov)
This report provides technical guidance about common vaccination concerns for clinicians and other health-care providers who administer vaccines to infants, children, adolescents, and adults. (cdc.gov)
Any person or institution that provides vaccination services should adopt these standards to improve vaccination delivery and protect infants, children, adolescents, and adults from vaccine-preventable diseases. (cdc.gov)

Finding an egg donor through Takes3 , NAFG's egg donor program, is easy: you choose an available donor from our database, and then your donor goes to your clinic for the screening and donation. (assistedfertility.com)
Egg donation is certainly not for everyone. (middleclassdadmoney.com)
Although age is not a telling sign of maturity, it is considered that adults less than 20 may not be able to handle what comes with egg donation. (middleclassdadmoney.com)
3 days before organ procurement, the organ donor received a blood transfusion from a donor who had received a yellow fever vaccine 6 days before blood donation. (cdc.gov)

As embryonic development proceeds, stem cells lose their pluripotency. (orthodoxwiki.org)

The first offspring to develop from a differentiated cell were born after nuclear transfer from an embryo-derived cell line that had been induced to became quiescent. (todayinsci.com)
A breakthrough in somatic cell nuclear transfer opens the possibility of producing human embryonic stem cells with a patient's own genes. (the-scientist.com)
The first pluripotent human embryonic stem cells (hESCs) have been generated from somatic cell nuclear transfer, according to a study published today (October 5) in Nature . (the-scientist.com)
The advance here is the proof that somatic cell nuclear transfer can work [in human cells] and can fully reset the donor cell genome to a pluripotent state," said Harvard Medical School's George Daley , who was not affiliated with the study. (the-scientist.com)
Somatic cell nuclear transfer has shown limited success in animal studies, which have successfully isolated pluripotent cells. (the-scientist.com)
In humans, somatic transfer has been less fruitful-the egg cell quits dividing and often dies after nuclear transfer. (the-scientist.com)
Here we describe the cloning of two Afghan hounds by nuclear transfer from adult skin cells into oocytes that had matured in vivo . (nature.com)
Successful somatic-cell nuclear transfer (SCNT) depends on the quality, availability and maturation of the animal's unfertilized oocytes. (nature.com)
Figure 1: Dog cloned by somatic-cell nuclear transfer. (nature.com)
The primary cloning technique is called "somatic cell nuclear transfer" (SCNT). (cbc-network.org)
