1st synthetic mouse embryos — complete with beating hearts and brains — created with no sperm, eggs or womb

For the first time, scientists have created mouse embryos in the lab without using any eggs or sperm and watched them grow outside the womb. To achieve this feat, the researchers used only stem cells and a spinning device filled with shiny glass vials.  The experiment is a “game changer,” Alfonso Martinez Arias, a developmental …

Scientists create world’s first ‘synthetic embryos’ | Medical research

Researchers have created the world’s first “synthetic embryos” in a groundbreaking feat that bypassed the need for sperm, eggs and fertilisation. Scientists at the Weizmann Institute in Israel found that stem cells from mice could be made to self-assemble into early embryo-like structures with an intestinal tract, the beginnings of a brain, and a beating …

Synthetic Embryo Models May Enable Growing Organs for Transplantation

Credit: Weizmann Institute of Science Without Egg, Sperm or Womb: Synthetic Mouse Embryo Models Created Solely from Stem Cells An egg meets a sperm – that’s a necessary first step in life’s beginnings. In embryonic development research, it’s also a common first step. However, in a new study published on August 1, 2022, in the …
