Stem Cells and Lung Regeneration

ABSTRACT

Tissues such as the lung, liver, and pancreas that have a low steady-state cell turnover yet can respond robustly after injury to replace damaged cells. The airway epithelium is exposed to inhaled particles and pathogens that may lead to the development of a many infectious and inflammatory respiratory diseases. Lung transplantation is an accepted modality of treatment for end-stage lung diseases. Since the early 1990 s, more than 26,000 lung transplants have been performed at centers worldwide. However, the availability of donor tissues and organs is limited, which presents a serious limitation for widespread transplantation surgery. The appearance of bioengineered lung and tracheal tissue transplants is considered a promising alternative to the classical transplantation of donor organ/tissue. Stem cells therapy arises as a new therapeutic approach, with a wide application potential.
