How to grow a Hamburger: Mark Post @ TED

Nachtrag zum Frankenburger gestern: Mark Post von der Maastricht University hatte auf einer TED-Konferenz in Haarlem im Detail erklärt, wie man einen Hamburger in einer Petrischale züchtet.

This hamburger contains 60 billion cells. Now, that’s a lot. You need to culture a lot of cells. You need to somehow find a way to do that efficiently because, remember, we have to be more efficient than the cow or the pig…

It has to be efficient and it has to also be meat. Not some kind of substitute. We have more than enough substitutes from vegetable proteins. It needs really to be meat. Nothing less, nothing more…

It takes about 7-8 weeks to grow a muscle fiber, and so, also 7-8 weeks to grow a hamburger. You could do it at home if you like … If you have the right materials, it’s very, very easy to do. And in fact [the] stem cells … they survive freeze-drying, so you could envision that over the Internet we would eventually sell little, sort of, tea bags of stem cells — from tuna, from tiger, from cows, from pigs, from whatever animal you could imagine. Then, in the comfort of your own kitchen, you could grow your own tissue. You would have to know what you want to eat 8 weeks in advance — because it takes a while.
