Why should scientists cultivate human organs in space?

Beijing time, July 13, according to foreign media reports, people in space environment, zero gravity may affect the normal growth of human organs, which is why space experiments are valuable, astronauts in the International Space Station conducted a series of scientific experiments, from a new perspective of biological science to explore the growth of human tissue mystery.
gravity interferes with cellular behavior and produces polarized tissue by affecting the interaction of proteins and genes within cells, which is a fundamental step in the development of natural organs.
However, gravity interferes with developmental processes when we try to replicate complex 3D tissue for medical transplants in the laboratory.
labs to grow human organs and tissues In order to grow organ tissue in the laboratory, scientists use stents to provide a cell surface attached to a predetermined rigid rigid structure.
for example: an artificial kidney requires a specific structure or stent to supply kidney cells to grow.
yes, this strategy helps human tissue form at an early stage, but in the long run there are problems, such as synthetic stents or the wrong structure that produce the ultimate immune response.
, by contrast, cells can be freely organized into the correct three-dimensional structure without the need for a stent matrix.
in zero-gravity conditions in space, the researchers found possible new ways of human tissue growth, such as cartilage and blood vessels grown without stents, to simulate their natural cell arrangement in an artificial environment, and while this is not a process of development in the womb (the uterus is also affected by gravity, after all), the space zero-gravity environment has some advantages for studying the growth of human tissue tissue.
the International Space Station is conducting the study, and currently astronauts are conducting a series of experiments to study optimizing tissue growth and analyzing basic science, personalized medicine and organ transplants.
But there are other reasons why we cultivate organ tissue in the space environment, long-term space missions will cause a series of physiological changes in the astronaut's body, over time, some physiological changes in the human body are reversible, while others are not, which will endanger future human space flight.
studying the physical state of astronauts before and after a space mission can reveal how their organs have changed, but the mechanisms that cause the observed changes do not explain the causeof them.
so growing human tissue in space can complement such research and help explore solutions.
all life forms we know so far evolve in a microgravity environment, without gravity, our brains may evolve on different trajectories, or our livers may not filter toxins in the body as they did during life on Earth.
by reconstructing the formation of embryonic organs in the space environment, we can predict how human uterine embryos will develop.
on the International Space Station, the astronauts' scientific lab is conducting research on organic organs of the human brain to understand the effects of zero gravity on human brain development.
these projects will have far-reaching implications for future human colonization of space, and will continue to improve the quality of artificial organs and better adapt to drug testing and treatment.
