It tells us that these cells from the small airways in our lungs, actually have these hairlike structures that you would expect to see in the lung.

And we've put intestinal human cells in a gut on a chip, and they're under constant peristaltic motion, this trickling flow through the cells, and we can mimic many of the functions that you actually would expect to see in the human intestine.

There's fluid flowing across these cells, so we can begin to interconnect multiple different chips together to form what we call a virtual human on a chip.

Now imagine if we could take cells from all those different populations, put them on chips, and create populations on a chip.

Now, let's imagine a little bit what the future might look like if I could take your stem cells and put them on a chip, or your stem cells and put them on a chip.

So 100 years ago, hormones had just been discovered, and people hoped that hormone treatments were going to cure aging and disease, and now instead we set our hopes on stem cells, genetic engineering, and nanotechnology.

That red layer is a tough outer layer of dead skin, but the brown layer and the magenta layer are jammed full of immune cells.

We target thousands upon thousands of these particular cells just residing within a hair's width of the surface of the skin.

So what if you've targeted cells?

Our investigators have found that there are certain genes in the lung tumor cells of both women and men.

Now the average human ejaculate has about 300 million sperm cells, so it's already a competitive environment.

They keep the sperm cells cool so you can have frequent ejaculations.

Okay? (Laughter) So the brain is terribly simple: it's made up of four cells, and two of them are shown here.

And when these four cells work together in health and harmony, they create an extraordinary symphony of electrical activity, and it is this electrical activity that underpins our ability to think, to emote, to remember, to learn, move, feel and so on.

But equally, each of these individual four cells alone or together, can go rogue or die, and when that happens, you get damage.

It's amazing and it's occurred because there are stem cells in the brain, even, which can enable new myelin, new insulation, to be laid down over the damaged nerves.

We can use stem cells, and specifically we can use human stem cells.

And human stem cells are these extraordinary but simple cells that can do two things: they can self-renew or make more of themselves, but they can also become specialized to make bone, liver or, crucially, nerve cells, maybe even the motor nerve cell or the myelin cell.

And the challenge has long been, can we harness the power, the undoubted power of these stem cells in order to realize their promise for regenerative neurology?

Take a skin cell, make it a master pluripotent cell, so you could then make those cells that are relevant to their disease, both to study but potentially to treat.

So to return to the original problem, what is the opportunity of these stem cells, or this disruptive technology, for repairing the damaged brain, which we call regenerative neurology?

It's very simple: You take a patient with a disease, let's say motor neuron disease, you take a skin sample, you do the pluripotent reprogramming, as I've already told you, and you generate live motor nerve cells.

That's straightforward, because that's what pluripotent cells can do.

And what you're looking at, and this is amazing, these are living, growing, motor nerve cells from a patient with motor neuron disease.

So apart from seeing them grow and put out processes, we can also engineer them so that they fluoresce, but crucially, we can then track their individual health and compare the diseased motor nerve cells to the healthy ones.

But I want to come back to how you might use stem cells directly to repair damage.

The first, and I think in the long run the one that will give us the biggest dividend, but it's not thought of that way just yet, is to think about those stem cells that are already in your brain, and I've told you that.

All of us have stem cells in the brain, even the diseased brain, and surely the smart way forward is to find ways that you can promote and activate those stem cells in your brain already to react and respond appropriately to damage to repair it.

But the other way is to effectively parachute in cells, transplant them in, to replace dying or lost cells, even in the brain.

We took patients with multiple sclerosis and asked a simple question: Would stem cells from the bone marrow be protective of their nerves?
