World's First Working Organ Grown in An Animal from Lab-Created Cells (image) University of Edinburgh Share Print E-Mail Caption Scientists have grown a fully functional organ from transplanted laboratory-created cells in a living animal for the first time. They grew a working thymus -- an important organ that supplies the body with immune cells. Left: Specialised thymus cells were created in the lab from a completely different cell type using a technique called reprogramming. Right: The laboratory-created cells were transplanted onto a mouse kidney to form an organised and functional mini-thymus in a living animal.
