It is a moment I will always remember. On a warm summer's day in Wroclaw, Poland, Darek Fidyka walked across a bridge, using only a frame for support.
This had been his dream for four years, after he was paralysed in a knife attack. Now, after a transplant of cells taken from his nasal cavity, it had become reality.
He is the world's first patient to receive the groundbreaking treatment.
Behind those few steps lay the extraordinary efforts of a group of scientists, surgeons and fundraisers in Britain and Poland.
