Could a stem cell jab stop your eyesight from failing? We look at some of the treatments being tested in Britain

From easing creaky knees to mending a damaged heart, it seems that scientists are on the brink of using stem cells to revolutionise treating a range of conditions.

These master cells are essentially the building blocks of human tissue, and some have the capacity to turn into any type of specialist cell, such as skin, muscle or nerve.

Stem cells were hailed as a major medical breakthrough in the late Nineties when scientists discovered how to grow them in the lab.

There are currently two stem cell- based treatments approved for use. We look  into some of the treatments

But early progress was stymied, partly because these cells were originally harvested from embryos, leading
