Scientists have created the newest technique that is able to keep brain tissue alive and functioning for 25 days. The technique, developed by scientists from Japan is based on the use of microfluidic substances in order to prevent drying of the tissue of the mouse brain. A new technique can be used not only to study tissue but also to improve technology for studying organogenesis.
Can the brain function outside the body?
The brain is a critical organ responsible for the activity of the whole living organism. The structure of the brain is a complex organ that consists of several types of fabrics interconnected by nerve fibers. Brain tissue is very difficult to research because of its complex structure, and despite improved methods of research and modern technologies, many processes occurring within the brain tissue, are still unknown to science.
Despite this fact, the scientists were able to make functioning brain tissue of mice, even outside of the body. If early scientists have experienced a lot of difficulties during the research due to the rapid vydyhaemoy and the death of tissue outside nutritious and hydrated culture medium, the experiment was able to show that brain cells can survive in very extreme conditions and circumstances.
What do you think, does humanity carry out such experiments for scientific purposes? Let's try to discuss this issue in our Telegram chat.
The newest way allows you to bypass most of the problems associated with transplantation of brain tissue, due to the device having a semi-permeable channel, which is covered with an artificial membrane, and also due to the special walls of the chemical substances used as antifoaming agent in pharmaceuticals. Thus, the tissues no longer need constant immersion, but at the same time they are powered from a moist nutrient medium that is circulated in the semipermeable channel and thus does not violate the natural gas exchange.

When learning a new technology was used modified mice in which the circadian activity rhythm is directly connected with the production of the fluorescent proteinthat enables scientists to track the viability of the tissue, due to the amount of the produced bioluminescence. As a result of researches scientists came to the conclusion that the tissue is able to maintain viability for more than 25 days, which can make a real revolution in biology and medicine. However, the experiment may lead to problems relating to moral and ethical standards, prompting a large number of questions from animal welfare activists.
