Yes, that seems to be true. Here is a description of the work which was done:
- The 2010 research involved destroying the cells of rat lungs by repeatedly freezing and thawing and then “reseeding” the lungs with embryonic stem cells from mice.
Following that work up with similar but more large-scale experiments on pig lungs, the researchers now applied the same regenerative engineering principles to human lungs.
Taking lungs from two children who had died from trauma (most likely a car accident), the researchers stripped one of the lungs down to a bare “skeleton” of just collagen and elastin - the main proteins in connective tissue.
Using this stripped-down lung as a “scaffold,” they then harvested cells from the other lung, which were applied to the scaffolding.
This lung structure was then placed in a chamber filled with a nutritious liquid, which Nichols describes as "resembling Kool-Aid.*
The purpose of this research is to grow diseased lungs which can be used to test stem-cell therapies.
