The structure of a human heart has now been replicated in miniature in the laboratory Science Photo Library/Alamy
Stem cells have been used to grow an embryonic-like “heart” that can pump fluid around a system of tiny channels on a laboratory slide.
The mini-heart could allow researchers to explore how physical forces, such as blood flow, shape the early stages of human heart development and give new insights into congenital heart defects.
Current efforts to grow human heart tissue involve coaxing human stem cells to form spheres of heart tissue, known as organoids, in …
