The cells were inserted in macaque embryos in petri dishes Credit: REUTERS Scientists have grown human cells in monkey embryos with the aim to understand more about how cells develop and communicate with each other. Researchers from the Salk Institute in California have produced what is known as monkey-human chimeras, with human stem cells - special cells that have the ability to develop into many different cell types - inserted in macaque embryos in petri dishes in the lab. However, some ethicists in the UK have raised concerns, saying this type of work "poses significant ethical and lega...

(Photo : Photo: Screenshot from Instagram) Genetic chimerism, also known as a chimera, is a single organism made up of cells with several genotypes. In species, this refers to an organism originating from two or more zygotes. It might include blood cells of various blood types, minor differences in structure (phenotype), and even the possession of both female and male sex organs if the zygotes were of different sexes. Ethical Discussion (Photo : Pixabay) Many scientists have expressed reservations about the procedure, claiming that although the embryos, in this case, were killed after 20 days...

BBC News By Helen Briggs image captionHuman cells were grown in an early monkey embryo Monkey embryos containing human cells have been made in a laboratory, a study has confirmed. The research, by a US-Chinese team, has sparked fresh debate into the ethics of such experiments. The scientists injected human stem cells - cells that have the ability to develop into many different body tissues - into macaque embryos. The developing embryos were studied for up to 20 days. Other so-called mixed-species embryos, or chimeras, have been produced in the past, with human cells implanted into sheep and ...

Ethical concerns raised over human cells grown in monkey embryos UK experts have called for public discussion and debate about the ethical and regulatory challenges on human-animal chimeras. 15 April, 2021 15:00 US scientists have grown human cells in monkey embryos with the aim to understand more about how cells develop and communicate with each other. Researchers from the Salk Institute in California have produced what is known as monkey-human chimeras, with human stem cells – special cells that have the ability to develop into many different cell types – ...
