Research that has now sparked ethical debate involves growing human stem cells in monkey embryos. In breakthrough research, a team consisting of biologists from the US and China developed a human-monkey hybrid in laboratory settings. For this purpose, scientists injected human stem cells in embryos in Macaques monkeys and then observed them for 20 days, before all of them got destroyed on their own.

A joint team of US and Chinese scientists have, in breakthrough research, grown human cells in monkey embryos in a laboratory for up to 20 days. The development, which has sparked ethical debates, has implications for developing new models of human biology and disease.
Interspecies chimeras in mammals have been made since the 1970s, when they were generated in rodents and used to study early developmental processes.
In the current study, detailed in the journal Cell, six days after the monkey embryos had been created, each one was injected with 25 human cells. The cells were from an induced pluripotent cell line known as extended pluripotent stem cells, which have the potential to contribute to both embryonic and extra-embryonic tissues.

Scientists have created human-cross-monkey embryos in a US laboratory in controversial research aimed at developing new treatments for human diseases.
Researchers at the Salk Institute for Biological Sciences in California injected human stem cells into over 100 macaques embryos - a species of monkey found throughout Asia and northern Africa.
They then examined them under microscope for 20 days to see how they would develop.

After just one day, human cells had combined with 132 of the macaques embryos and after 10 days, 103 were still developing.
The longest any of the embryos lasted was 20 days.
