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.
