Default Human-pig 'chimera embryos' detailed

Human-pig 'chimera embryos' detailed
The embryos were allowed to develop for 28 days

Embryos that are less than 0.001% human - and the rest pig - have been made and analysed by scientists.

It is the first proof chimeras - named after the mythical lion-goat-serpent monster - can be made by combining material from humans and animals.

However, the scientific report in the journal Cell shows the process is challenging and the aim of growing human organs in animals is distant.

It was described as an "exciting publication" by other researchers.

To create a chimera, human stem cells - the type that can develop into any tissue - are injected into a pig embryo.

The process appears very inefficient - of the 2,075 embryos implanted only 186 continued to develop up to the 28-day stage.

But crucially there were signs that human cells were functioning - albeit as a tiny fraction of the total tissue - as part of a human-pig chimera.

"This is the first time that human cells are seen growing inside a large animal," Prof Juan Carlos Izpisua Belmonte, from the Salk Institute, told the BBC News website.

Pardon the pun - the research into this very specific field is still embryonic. It will interesting to see what proves more likely to be developed - tissues & organs within the organs/tissues of other animals or a more 'synthetic' environment. Who knows? Both may prove appropriate - for different functions.
