Miracle or meddling? 'Chimeric' monkeys made from cells of six different 'parents' spark protests

Scientists at the Oregon Primate Centre have created monkeys which each contain a cocktail of cells from other embryos. Scientists say they could help stem cell research - but animal campaigners are horrified

They may look like any other baby monkeys, but these two are scientific breakthroughs.
Roku and Hex are the world’s first chimeric monkeys – created with genetic material from six ‘parents’.
But their birth has caused an ethical storm, with critics accusing scientists of disregarding the welfare of the animals.

Roku and Hex: Named after the fire-breathing creature in Greek mythology composed of parts of multiple animals, chimeras are organisms made up of cells from two or more genetically distinct sources.

Twins Roku and Hex, whose respective names come from the Japanese and Greek for ‘six’, have been created with genetic material from six monkeys.
Researchers from Oregon Health and Science University in the U.S. extracted cells from six macaque embryos and combined them into a single embryo in a laboratory before implanting it into a surrogate mother monkey.

Roku: The monkeys were created by 'gluing together' cells from several other embryos

Three male babies were born using this process – Roku and Hex, who are twins, and Chimero.
However, to reach this stage, dozens more embryos were experimented on, and some surrogate pregnancies were aborted.
While most animals only contain cells in which the genetic material from their two parents has mixed together, the chimeric monkeys’ bodies contain six different types of cell – holding distinct DNA from each biological parent.

A 'chimeric' blastocyst cell: The monkeys were created from cells of six other embryos

Scientists at the Oregon Primate Centre have created monkeys which each contain a cocktail of cells from other embryos. Scientists say they could help stem cell research - but animal campaigners are horrified.

'The monkeys who do exhibit characteristics of ‘interest’ are destined to suffer greatly by their very nature, and via the experiments to which they will be subjected.'

'The cells never fuse, but they stay together and work together to form tissues and organs,' said lead scientist Dr Shoukhrat Mitalipov, from the Oregon National Primate Centre. 'The possibilities for science are enormous.'
