Stem cell research is really in its infancy. The possibility of generating new lung tissue is years away. There is no research on its use for pulmonary fibrosis. You may find further leads to other resources from the research study that you noted. Here is the full citation. Human pulmonary chimerism after hematopoietic stem cell transplantation by Benjamin T. Suratt, MD et al in American Journal of Respiratory & Critical Care Medicine, Volume 168, Number 3, pages 318-322, Aug 1, 2003.

"I have compiled reports on all of the researchers I am aware of that are currently working on lung tissue regeneration. These reports can be found at the yahoo Group:
