How scientists have transplanted a lab-grown lung into a pig

The video explains the process of bioengineering pig lungs. It starts by taking a lung from a pig and bathing it in a sugar and protein solution to remove blood and cells, leaving a lung skeleton. This scaffold is then treated with growth factors, hydrogels, and nanoparticles to prepare it for receiving cells from the pig intended for transplantation. The researchers observed that pigs with bioengineered lungs developed blood vessel networks within two weeks.
