And so one of the things you can think about doing is actually making scaffolds with slightly different dimensions that might be able to surround your cells in 3D and give them a little bit more information.

And there's lots and lots of stem cell trials going on worldwide, and they use many different types of cells, but one common theme that seems to be coming out is that actually, very often, those cells will die once you've implanted them.

And you can either put them into the heart or into the blood system, but either way, we don't seem to be able to get quite the right number of cells getting to the location we want them to and being able to deliver the sort of beautiful cell regeneration that we would like to have to get good clinical outcomes.

We still need chemistry, we still need mechanics, we still need really interesting topography, and we still need really interesting ways to surround the cells.

But now, the cells also would probably quite like a material that's going to be able to be conductive, because the cells themselves will respond very well and will actually conduct signals between themselves.

So I came up with my own way to count cells in the brain, and it essentially consists of dissolving that brain into soup.

Now, the beauty of a soup is that because it is soup, you can agitate it and make those nuclei be distributed homogeneously in the liquid, so that now by looking under the microscope at just four or five samples of this homogeneous solution, you can count nuclei, and therefore tell how many cells that brain had.

Alongside growth and sexual maturity, this system regulates everything from your sleep to the rhythm of your beating heart, exerting its influence over each and every one of your cells.

From there, each hormone needs to locate a set of target cells in order to bring about a specific change.

By exposing millions of cells at a time to hormones in carefully-regulated quantities, the endocrine system drives large-scale changes across the body.

These hormones travel to most of the body’s cells, where they influence how quickly those cells use energy and how rapidly they work.

Sometimes disease, stress, and even diet can disrupt that regulatory function, however, altering the quantity of hormones that glands secrete or changing the way that cells respond.

They are cells in dishes and animal testing.

Now let's talk about the first one, cells in dishes.

So, cells are happily functioning in our bodies.

We need human cells, but we need to find a way to keep them happy outside the body.

Our cells experience that.

So if we want to make cells happy outside our bodies, we need to become cell architects.

We need to design, build and engineer a home away from home for the cells.

We have living cells in that little chip, cells that are in a dynamic environment interacting with different cell types.

There's been many people trying to grow cells in the lab.

We're simply trying to recreate in this tiny chip the smallest functional unit that represents the biochemistry, the function and the mechanical strain that the cells experience in our bodies.

We use techniques from the computer chip manufacturing industry to make these structures at a scale relevant to both the cells and their environment.

In the center, we have a porous, flexible membrane on which we can add human cells from, say, our lungs, and then underneath, they had capillary cells, the cells in our blood vessels.

And we can then apply mechanical forces to the chip that stretch and contract the membrane, so the cells experience the same mechanical forces that they did when we breathe.

We could, for example, mimic infection, where we add bacterial cells into the lung.

then we can add human white blood cells.

White blood cells are our body's defense against bacterial invaders, and when they sense this inflammation due to infection, they will enter from the blood into the lung and engulf the bacteria.

We've labeled the white blood cells so you can see them flowing through, and when they detect that infection, they begin to stick.

Now I want to share this picture with you, not just because it's so beautiful, but because it tells us an enormous amount of information about what the cells are doing within the chips.
