Abstract
Stem cells are multipotent/pluripotent source of a wide range of cell lineages that are crucial for tissue development, repair, and regeneration. They are undifferentiated cells that can characteristically self-renew and develop into different cell types that perform various functions in the human body. Stem cells play critical roles in body development and growth through childhood. Recent data indicate that pools of adult stem cells are also important in some examples of the repair and regeneration in adult tissues. Stem cells can self-renew to maintain the tissue-specific pool of stem cells and differentiate into various functionally specialized cell types. Considerable data have accumulated in recent years on the characterization, isolation, and function of stem/progenitor cells in the lung. In this book chapter, we describe accumulated data on the localization, characterization, biology, and function of different lung stem cell populations such as alveolar, bronchial, and tracheal epithelial cells, as well as endogenous mesenchymal stem/progenitor cells.
