Lab-grown lungs transplanted into pigs after 15 yrs of study
Scientists at the University of Texas, who were the first to bioengineer human lungs in 2014, have successfully transplanted lab-grown lungs into pigs after 15 years of research. The cells used to grow each lung came from respective lungs of the four study animals. The lungs were grown for 30 days and weren't rejected even after two months of transplantation.
