Stem cells are much hyped – and genuinely full of potential for both medicine and biology.

I wanted to make a platform for the world class scientists who have devoted their lives to the discoveries of stem cells and what they can do.

We created a collaborative working space where the scientists could take charge of what information was seen as important, how it should be contextualised, and what they saw as the most significant breakthroughs.

The result is a film of great clarity and precision: a surprising scope from World War II to the fifth floor of an eye hospital in India.
