Abstract: Stem cells, which are a type of primitive cells with multipotent differentiation potential and self-renewal ability, have the potential to regenerate various tissues and organs. Stem cell drug development is a frontier research field in life sciences. Extensive clinical trials involving stem cells have been conducted for different complicated diseases. Some stem cells have been approved as drugs for some indications, indicating their broad industrial prospects. This review introduces the progress of stem cell drugs around the world, especially in China, and discusses the main problems in the industrialization of stem cell drugs, such as their effectiveness, quality control and safety, so as to provide some reference and insight for the development and rapid industrialization of stem cell drugs.
