some people initially thought we were a little crazy.

But since then, much progress has been made,

both in our lab and other labs around the world.

And given this, we started getting questions like,

can you also grow animal products like meat and leather?"

quite frankly I thought they were a little crazy,

and on how we raise and slaughter billions of animals

to provide our meat, dairy, eggs and leather goods?

as the world's population expands to 10 billion,

and one of the biggest producers of greenhouse gases

when you get so many animals so close together,

which puts the environment, public health,

There is another way, because essentially,

animal products are just collections of tissues,

that are made of relatively simple tissues.

What if, instead of starting with a complex

we started with what the tissues are made of,

This is biofabrication, where cells themselves

like ears, windpipes, skin, blood vessels and bone,

that have been successfully implanted into patients.

And beyond medicine, biofabrication can be

a humane, sustainable and scalable new industry.

And we should begin by reimagining leather.

I emphasize leather because it is so widely used.

It is beautiful, and it has long been a part of our history.

Growing leather is also technically simpler

than growing other animal products like meat.

It is also less polarizing for consumers and regulators.

Until biofabrication is better understood,

more people would be willing to wear novel materials

than would be willing to eat novel foods,

In this sense, leather is a gateway material,

a beginning for the mainstream biofabrication industry.

it brings our other consumer bioproducts like meat

To grow leather, we begin by taking cells

and multiply them in a cell culture medium.

And we then coax these cells to produce collagen,

This collagen is the stuff between cells.

but in leather, it's the main building block.

And what we next do is we take the cells and their collagen
