Storyline: A 3D bioprinter used for mass production of organoids has become an eye-catching highlight at the ongoing 27th China International Hi-Tech Fair (CHTF), which its developer says can serve as a booster for drug development. The three-day fair opened on Friday in Shenzhen, a major tech hub in south China's Guangdong Province, bringing together over 5,000 exhibitors from around the world to showcase more than 5,000 new products and solutions. Despite the name, organoids, grown in the lab from stem cells, aren't miniature organs, but look like three-dimensional hollow balls of cells that closely mimic how the cells behave in the body. The machine was brought by a team from the Research Institute of Tsinghua University in Shenzhen. Xu Tao, director of the Bio-Intelligent Manufacturing and Live Printing Center of the institute, said that a heart-shaped organoid can be cultivated in about eight days. It not only possesses beating function but also has significant medical application value. "People take different medications, and these medications have certain effects on our organs, including the heart. Using a beating heart organoid, we can test whether the daily medications we take have a safe effect on our heart. In the future, we will use new technologies such as organoids to develop drugs for humans, which is already an important development trend," Xu said. The 3D bioprinter uses "bio-ink" made from functional cells differentiated from pluripotent stem cells. Through 3D printing, specific organoids can be made on a large scale, thereby helping people to develop various drugs. "What makes this machine special is that it is the world's first automated, high-throughput device for mass production of organoids. Its production efficiency can reach more than 100,000 organoids per day, which is currently the most advanced level in the world," Xu said.
