United States federal government announced plans to lift its ban on funding of controversial experiments using human stem cells to create animal embryos.
National Institutes of Health proposes a new policy to allow scientists to receive federal funds to create embryos, known as chimeras (half animal – half human embryos), but under certain conditions and closely monitored.
National Institutes of Health imposed a moratorium on the funding of these experiments semptemvri last year because they may raise ethical concerns.
One of those problems is the possibility scientists to create animals that have partially human brains, which will enable them to have some semblance of human consciousness or the ability to think like the man. Or even those animals able to develop man sperm and egg cells, and reproduce, thus producing human embryos or fetuses in animal or hybrid creatures.
But scientists claim that you can take steps to prevent these results, and those embryos provide an invaluable tool for medical research.
For example, they hope to use embryos to create animal models of human disease, which could lead to new ways to treat and prevent disease. Scientists also hope to produce sheep, pigs and cows with human heart, kidneys, liver, pancreas, and possibly other organs that can be used fmaor transplantation.
Some scientists are amazed at the National Institutes of Health would consider funding this type of research, but of course some criticize and condemn this step.
The public has 30 days to comment and shared his opinion about the proposed new policy. National Institutes of Health could launch projects for funding at the beginning of 2017.
