'New lungs' from stem cells

For the first time, scientists have succeeded in transforming human stem cells into functional lung and airway cells.

The advance, reported by Columbia University Medical Centre (CUMC) researchers, has significant potential for modelling lung disease, screening drugs, studying human lung development, and, ultimately, generating lung tissue for transplantation. The study was published today in the journal Nature Biotechnology.

"Researchers have had relative success in turning human stem cells into heart cells, pancreatic beta cells, intestinal cells, liver cells, and nerve cells, raising all sorts of possibilities for regenerative medicine," said study leader Hans-Willem Snoeck, MD, PhD, professor of medicine (in microbiology & immunology) and affiliated with the Columbia Centre for Translational Immunology and the Columbia Stem Cell Initiative.

"Now, we are finally able to make lung and airway cells. This is important because lung transplants have a particularly poor prognosis. Although any clinical application is still many years away, we can begin thinking about making autologous lung transplants – that is, transplants that use a patient's own skin cells to generate functional lung tissue."
