An Israeli startup is going to create personal clones for people for a spare set of organs.

Renewal Bio has shared plans to create realistic synthetic embryos that will be grown in artificial wombs from stem cells (without the use of sperm and eggs). Scientists have already conducted studies on mice. They placed mouse embryos in a mechanical womb and managed to grow them to such an extent that the brain began to emerge and the heart began to beat. Analyzes show that the synthetic versions are about 95% similar to normal mouse embryos, based on the mix of cell types within each.
