Bioartifical organs differ from, well, plain ol' artificial organs because
they consist of biomaterials and cells. And while bioartificial livers are
becoming increasingly commonplace, it's only recently that working lungs have
been grown in a lab. Working at the Massachusetts General Hospital and
Harvard Medical School in Boston, researchers removed the left lungs from
rats and stripped them of cells with a process that left the blood vessels,
airways, and connective tissues intact. Using all that as a sort of
scaffolding, lung cells were regrown on the scaffolding in a bioreactor. The
cultivation of the lungs took less than a week, and once they'd been run
through their paces in culture, they were transplanted into rats. At this
point, the lungs did their job for about six hours, after which "they failed
through accumulation of fluid inside the lung and resultant capillary
leakage," according to PhysOrg. According to the man in charge, Mass
General's Harald C. Ott, if work continues at the current pace we might begin
to see regenerated organs for human patients within the next ten years. To
see the thing in action, hit up that source link.
