The main advantage of embryonic organelles is that many cells develop in parallel inside them.
different fabrics.They exchange the same signals with each other that are critical for the proper growth of the embryo. The heart cells growing in them are in the same environment in which they would be located in a real embryo. Giuliana Rossi, a molecular biologist at the Swiss Federal Polytechnic School and one of the authors of the paper
Experiments with universal stem cells have been going on for several years: scientists have already tried to grow, for example, an analogue of the liver with their help.
Rossi's team has taken the first big step toward growing organs in vitro.
A group of scientists analyzed sets of signalswhich are needed for stem cells to begin to develop into certain tissues of the body. And the heart is the first organ that forms inside the embryo of multicellular organisms. Accordingly, the researchers decided to grow not a full-fledged heart, but its embryo.
The finished organ that resultedwork, began to contract, and also to produce and perceive signals characteristic of the developing heart. It is also noted that blood vessels began to grow around the organ.
The work continues, scientists intend to improve their developments in order to grow a human heart in the future.
