In the lung, more recent data have been accumulated on lung stem cell biology/function and the potential applications of stem cells in pulmonary diseases that are facilitated by the recent development of a broad range of cutting edge in vitro and in vivo research tools and approaches, including mouse and human organoid cultures, genetic editing in vitro and in vivo, human induced pluripotent cell (iPS cell) models of disease, haploid cells for genetic as well as compound screening paradigms, genetically engineered mice, and stem cell transplantation to cure diseases. Stem Cell Innovation in Health and Disease: Volume 2: The Lung, contains two major sections describing cutting edge research for understanding stem cell functions in the lung and respiratory system, and for developing methods to bring stem cells from bench to bedside; respectively. Each section includes insights ranging from using mouse and human organoid cultures, genetic editing in vitro and in vivo, and human induced pluripotent cells (iPSCs) to study stem cell functions and model lung diseases, through the cutting-edge research aiming to bring stem cells from bench to bedside, including the potential application of iPSCs, ESCs and blood stem cells (stem cell transplants) in the treatment of lung diseases/disorders. This book, therefore, discusses the fact-based promise of stem cells and regenerative medicine in the lung in the real world.
