Stem cell research yields advance against cystic fibrosis

Researchers at Harvard University have made another advance in the fight against cystic fibrosis using stem cells, adult stem cells:
Harvard stem cell researchers at Massachusetts General Hospital (MGH) have taken a critical step toward discovering in the relatively near future a drug to control cystic fibrosis (CF), a fatal lung disease that claims about 500 lives each year, with 1,000 new cases diagnosed annually. 
Beginning with the skin cells of patients with CF, Jayaraj Rajagopal and colleagues first created induced pluripotent stem (iPS) cells, and then used those cells to create human disease-specific functioning lung epithelium, the tissue that lines the airways and is the site of the most lethal aspect of CF, where the genes cause irreversible lung disease and inexorable respiratory failure.
For the record, embryonic stem cell research has yet to yield a single scientific advance, while adult stem cell research has yielded at least 90 advances.

  1. Stem cells are biological cells found in all multicellular organisms, that can divide through mitosis and differentiate into diverse specialized cell types and can self-renew to produce more stem cells. In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues.Stem Cell Therapies
