Researchers at the University of Texas say they have successfully grown pig lungs in the lab — and it may help pave the way for use of lab-grown organs in humans too.
In research published this week in the journal Science Translational Medicine, the U of Texas researchers say they used a lung scaffold — literally the outer casing of lung tissue, called the extracellular matrix — and coated it with a concoction of growth factors and chemicals that stimulate the cells to turn into lung cells.
Previous studies cultured cells for one week and the transplantation ultimately failed. So researchers used a 30-day time frame for this study and were able to develop an immature bioengineered lung, with cells and proper tissue
