An interesting and slightly bizarre story last week (behind a bit on this one, meant to post about it, then forgot).

Scientists, using stem cells, successfully grew a pair of human lungs, using one “stripped down” lung of collagen as a “scaffold.” They then painted the scaffold with cells from another lung (these lungs were harvested from children who likely were killed in a traffic accident), and grew a functioning lung.

“In terms of different cell types, the lung is probably the most complex of all organs – the cells near the entrance are very different from those deep in the lung,” UTMB researcher Dr. Joaquin Cortiella said.

“People ask us why we’re doing the lung, because it’s so hard. But the potential is so great, and the technology is here. It’s going to take time, but I think we’re going to create a system that works.”

This story specifically mentions that perhaps lungs can be grown for people with cystic fibrosis or COPD, but that transplants using grown lungs might be as far as 12 years away because of the need for considerable more testing (such as transplanting grown lungs in the bodies of animals to make sure they function.)

Exciting news. Slightly weird, but exciting.
