摘要:
The present invention provides anti-thrombogenic compositions, including anti-thrombogenic vascular grafts. In certain embodiments, the compositions comprise decellularized tissue coated with an anti-thrombogenic coating. The present invention also provides methods of preparing anti-thrombogenic compositions and methods of treatment comprising implanting the anti-thrombogenic compositions into a subject in need thereof.
摘要:
The present invention provides compositions and methods of preparing airway cells. In one aspect, an epithelial airway cell derived from an induced pluripotent stem (iPS) cell characterized by expression of airway cell surface markers and an ability to proliferate is described. In another aspect, methods of differentiating an iPS into an epithelial airway cell is provided. Engineered lungs, methods of making such engineered lungs comprising the epithelial airway cells and treating respiratory disorders are also disclosed.
摘要:
The present invention provides a bioreactor for large-mammal lung tissue. The bioreactor is capable of hydraulic driven negative-pressure and positive-pressure perfusion and ventilation. Perfusion and ventilation is delivered at physiological rates and is easily controllable. In one embodiment, the bioreactor comprises a support scaffold to support the size of a large-mammal lung tissue. In another embodiment, the bioreactor comprises a pleural sack that provides a small isolated fluid chamber which surrounds an engineered lung, thereby minimizing the amount of culture media needed. The present invention also provides an in vitro model for examining the function of a test agent and compositions and methods for alleviating a lung defect in a large-mammal.
