A new cloning experiment conducted in China in 2022 and described this month in Nature Communications marks the first successful cloning of a rhesus monkey. It was achieved using a slightly different approach to the conventional cloning technique used to [...]
Recently, Northwest University of Agricultural and Forestry Science and Technology (China) has reported the successful cloning of 3 “super cows” capable of producing more milk than normal. China is a pioneer in research in the area of cloning. In 2017, [...]
An ethical issue raised by experimentation with human embryos would be that modifying the genome could alter that of their descendants. A book entitled “Experiments in Democracy. Human Embryo Research and the Politics of Bioethics”, has just been published by [...]
Use chimeric animals as organ incubators, a hopeful means to resolve increasing organ shortage The shortage of human organs and tissues for transplantation represents one of the most critical unmet medical needs today. To address this problem, xenotransplantation, i.e. the [...]
The technique has ethical difficulties human embryo cloning and germline modifications Over the last few months, several articles have been published reporting genome editing experiments on human embryos (See HERE ). Now, a team of Chinese researchers has published a [...]
We thus consider it necessary to establish a moratorium on their use in humans, at least until more is known about these aspects. If this knowledge is obtained, ethical questions would still remain to be resolved, among which we consider [...]
After the cloning of Dolly the sheep (the first cloned sheep) 20 years ago this July, the possibility of using this technique to obtain animals that could be exploited for ethically sound purposes has been suggested. However, one problem that [...]
This study shows that the mtDNA variant in the individual has a great effect on its interaction with the nuclear DNA. This finding is contrary to what was thought of the effect of mitochondrial replacement. On 6th July this year, investigators [...]
Human somatic cell nuclear transfer (SCNT) or human cloning for reproductive and therapeutic purposes and oocyte use have ethical difficulties, principally that it objectifies the human embryo produced, it instrumentalises it, which goes against the dignity inherent to its own [...]
