Experimental mice have glowing hearts

According to Corney University-Welsh, scientists from the US and Japan have raised experimental mice with glowing hearts, fluorescent molecules with calcium implanted in the heart muscle of experimental mice, and activated when the heart muscle contracts.

But Japanese scientists had to make very small changes to the molecules, because to observe the internal organs, the fluorescence needed to light up, the heart of the lab rat every 10 seconds beating. times, so if there is no glowing molecular change it will be impossible to observe.

Using this method, biological engineers can observe the development of the heart in a laboratory fetus without breaking the embryo.

In the photographs taken during the experiment, they were also able to observe in the heart to develop two ventricles in turn, then four ventricles (these are the two stages of development on the 10th and 14th day after embryos are formed).

In addition, the researchers said that while experimenting with mice, they also discovered "decelerating cells" that prevent the transmission of the heart and ventricles at a new stage of development, but later on. This cell will go away. The researchers intend to introduce this new method to apply to other organizations, including neurological organizations. They hope that, in the future, this method can be used in clinical practice, implanting fluorescent cells into organizations that need to be diagnosed.
