23 Jul Tissue-engineered neural tissues and construction method thereof
Abstract
The invention discloses tissue-engineered neural tissues and a construction method thereof, belonging to the technical field of tissue engineering and regeneration medicine. Subcultured and purified neural stem cells serve as seed cells of the tissue-engineered neural tissues, a liquid type I collagen and Matrigel matrix serves as stent materials, and the seed cells and the stent materials are cultured after being compounded in vitro. A stent system adopted in the invention can be used for effectively maintaining the survival and proliferation of the neural stem cells, promoting the differentiation of the neural stem cells, and forming engineered neural tissues consisting of mature neurons, astrocytes and oligodendrocytes. The tissue-engineered neural tissues have an important significance in treating neural system injury through the transplantation of the tissue-engineered neural tissues, and can also serve as an in-vitro model for the psychological research of neurodevelopment, cerebral trauma and neuroelectricity.
