It’s true! Researchers at the University of Edinburgh announced that they had successfully developed in the lab a mature, fully functioning organ – a thymus – grown from cells harvested from a host creature. In this case, the animal was a mouse and the cells used to start the process were murine fibroblasts, a type of progenitor cell found in muscle tissues. Humans have them, too. Once the fibroblasts were isolated, scientists submitted them to specific growth factors which morphs the fibroblasts into T-cell producing thymus tissue.
While still in the animal model phase, researchers hope to translate this research to human models in the future.
