Synthetic embryo grown without sperm, womb. It has a brain and a beating heart

In a new medical breakthrough, scientists have successfully grown a synthetic embryo of a mouse without male sperm and a female womb. They used stem cells from mice to recreate the first stage of life and successfully developed an embryo with a brain, beating heart, and vitals for other organs.

The natural process of life was mimicked in the lab without eggs or sperm but with the body’s master cells, which can develop into almost any cell type in the body. The embryo was developed 8 ½ days after fertilization, containing the same structures as a natural one.

The study published in the journal Nature states that their result demonstrates the self-organization ability of embryonic and two types of extra-embryonic stem cells to reconstitute mammalian development. The researchers induced expression of a particular set of genes and established a unique environment for their interactions and got the stem cells to ‘talk’ to each other.
