Chinese scientists have reported findings recently in their latest experiments aboard the Tiangong space station: while brain cells migrates faster, muscle repair process is more slowly, and medicines for lipid metabolism disorders show a pronounced boost in potency in weightless environment.
The discoveries could reshape approaches to Alzheimer's therapy, muscle-atrophy prevention and next-generation drug research and development.
"Currently, our in-orbit observations show that neurons in organ-on-a-chip move faster in space than on the ground. This may indicate that the unique environment of space promotes cell movement in our brain tissue," said Jin Xuena, principal designer of life sciences of the Space Application Engineering and Technology Center under the Chinese Academy of Sciences.
A parallel experiment tracking skeletal-muscle precursor cells shows the opposite trend.
In the weightless environment, the cells' migration rate drops sharply and the overall timeline for muscle regeneration is delayed.
The finding underscores the difficulty of repairing damaged muscle in space.
A third study examined how lipid-nanoparticles ferry nucleic-acid drugs into cells.
On-orbit data reveal that cellular uptake of the drug is markedly higher in microgravity, and levels of disease-related proteins decline more rapidly.
"In a space environment, the therapeutic effects of drugs for lipid metabolism disorders are significantly enhanced. Therefore, the microgravity environment in space may serve as a new approach for future drug intervention or drug development," said Jin.

China's Commerce Minister Wang Wentao met with visiting German Foreign Minister Johann Wadephul in Beijing on Monday, and called on German companies to seize opportunities and deepen cooperation with Chinese partners in traditional and emerging sectors.
Wang noted that economic and trade cooperation between China and Germany has helped both sides develop industrial integration, interconnected markets, and complementary technologies, stabilizing and deepening bilateral relations, while also promoting the healthy development of China's trade and economic relations with the European Union (EU).
"We welcome German companies to seize new opportunities, consolidate cooperation in traditional sectors including machinery, automobiles, and chemicals, and tap the potential for cooperation in emerging businesses such as clean energy, intelligent manufacturing and biopharmaceuticals," said Wang.
Wang also noted that the current trend of politicizing trade and economic issue is on the rise, and global industrial and supply chains are being severely disrupted as a result. China and Germany, as well as China and the EU, should uphold free trade and safeguard the multilateral trading system with the WTO at its core, Wang said.
Wadephul said Germany opposes protectionism and considers China its most important trading partner. He added that Germany wants to maintain and expand the positive momentum of cooperation.
"China is a driver of innovation and a major hub for high technology in many aspects. We are very keen to maintain exchanges with China both economically and scientifically," said Wadephul.
China and Germany are the world's second and third biggest economies. According to German data, China was once again Germany's largest trading partner in the first three quarters of this year.
