Key Facts About Chicken Heart Beating Inside Eggs

The "windowing" technique is the technology currently used to study the development of the central nervous system and peripheral nervous system. Researchers at Oxford University, England and the Marine Biology Laboratory in Massachusetts, USA, use this technology to open chicken egg shells and record this rare image.

First, the scientists cut an open space like a window in an egg. They then pump ink into the artery of the embryo to observe the throbbing heart of the future chicks.

Of course, the egg in this experiment was fertilized and began to develop into an embryo.

Thanks to the "windowing" technique, scientists can cut open the eggshell several times and close it without breaking the embryonic development.
