Abstract
On April 6, 2016, the SJ-10 recoverable microgravity experimental satellite (SJ-10 satellite) was launched from Jiuquan in China, which conducted a mission of space microgravity experiments. As a recoverable satellite, the SJ-10 satellite provided an effective, open, and comprehensive platform to study space life and microgravity science. The SJ-10 satellite program consisted of 27 experiments including both fields of microgravity and space life sciences. Among the experiments, “three-dimensional (3D) cell culture and tissue restoration of NSCs under microgravity” proposed by Dr. Jianwu Dai and his staff was selected from more than 200 applications. This project was characterized by two aspects: neural stem cells and 3D culture. It was the first time that in vitro-cultured NSCs experienced a microgravity environment in space. 3D culture provided a specialized environment to benefit the in vitro tissue constructs. NSC-based therapy has attracted attention in recent years, which may be a promising treatment for many neurological diseases such as spinal cord injury, Alzheimer’s disease, stroke, and Parkinson’s disease. The 3D culture of NSCs under microgravity may provide valuable data for tissue reconstruction of the nervous system. To communicate the background and progress of this research, this review focuses on the key points of NSCs, 3D culture, and microgravity.
