Stem Cell Therapy: Replacing Damaged Cells with Novel Device
The project has developed a novel nano-substrate for safe and swift cell culture. It can effectively reduce the risk of carcinogenesis or inflammation in stem cell therapy by minimising the use of growth factors. This invention has been successfully patented in the US, China and Europe, and has been published by the renowned journal, Advanced Science (IF:15.8).
Incurable neurodegenerative diseases have been long regarded as a serious threat to global health. Stem cell therapy, which promises to cure those incurable diseases, uses stem cells to cultivate new and normal cells, tissues or organs. These can then be transplanted into the patient to restore physiological function by replacing damaged or dead cells. Currently, commercial stem cell cultivation usually requires various growth factors and organic compounds. However, the overuse of growth factors has been found to cause a high risk of carcinogenicity or inflammation in vivo after transplantation, and as a result, they have been prohibited from clinical cell processing by the Food and Drug Administration (FDA, US). To tackle this problem, we invented a novel medical device which is composed of biocompatible extracellular nanomatrices to swiftly and specifically differentiate neural stem cells into functional neurons to treat neurodegenerative diseases with the minimum usage of growth factors, enabling us to meet the FDA requirement for in vivo cell therapy. We have submitted a 513(g) application to the FDA to determine the correct classification of our product.
