Researchers at the University of Texas Medical Branch are using autologous (the patient’s own) stem cells to successfully transplant entire lungs without the risk of rejection. In animal models, researchers obtained a lung from a donor and removed all blood and cells, leaving a lung scaffold. Then, they obtained autologous lung stem cells from the subject and seeded the lung scaffold so that the lung would be repopulated. This created a brand new lung for transplantation, comprised of cells that would not be rejected because they are the patient’s own. When implanted back into the body, the engineered lungs were able to grow and vascularize with no additional treatments or infusions. This protocol could potentially be expanded to provide life-saving organs for hundreds of thousands of patients waiting for organ transplants, which, besides the obvious shortage, still pose a risk of immune rejection.
"The bio engineered lungs continued to develop post-transplant without any infusions of growth factors, the body provided all of the building blocks that the new lungs needed," commented lead researchers Joan Nichols and Joaquin Cortiella.
As treatments emerge, we believe the best stem cells to use will be the patient’s own [autologous stem cells] as this negates the need to find a suitable donor and eliminates the chances of rejection of the transplanted tissue.
