Rebuilding bodies.

Surgeons have recently discovered a way to take cells from a patient's own body and reprogram them to replace other cells.

These stem cells can be found inside the soft tissue interior of large bones like the hip.

Surgeons think that stem cells could have two important applications.

Firstly, they could be used to cure diseases like cancer where the body reproduces harmful or malignant cells.

Secondly, in cases where patients have lost body tissue, like muscle, stem cells could help the body regenerate them.

The recent case of Claudia Lorena Castillo Sanchez was the first step towards this.

Claudia's respiratory system had been damaged by tuberculosis, and she needed a new trachea.

Surgeons decided to transplant a new organ from a donor patient, but were worried that Claudia's immune system might reject it.

So, the medical team in Barcelona used her own stem cells to cover the new trachea.

The operation was a success, and Claudia now has a full and active life.
