Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos.
The cells show remarkable, collective behavior, almost as if they instinctively “know” what to do. This breakthrough allows researchers to explore genetic influences on development, reproductive challenges, and potential fertility treatments—all without using actual embryos.
