情態副詞

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.

不只在我們的實驗室，全球皆然

And given this, we started getting questions like,

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

能否製造動物產品？例如肉和皮革」

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?

提供我們所需的肉、乳、蛋、和皮製品？

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

這是生物製造(biofabrication)，利用細胞

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

例如耳朵、氣管、皮膚、血管、骨骼

that have been successfully implanted into patients.

And beyond medicine, biofabrication can be

醫學用途之外，生物製造也可以是

a humane, sustainable and scalable new industry.

人道、永續、容易調整規模的新工業

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.

對於消費者和監管單位也較無爭議

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,

然後我們誘導細胞製造膠原蛋白

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
