Need a new liver? Just print one: 3D printer makes working human liver
Metro ^ | November 9, 2013

Posted on 11/09/2013 7:21:32 PM PST by 2ndDivisionVet

A group of US scientists have created the world’s smallest human liver which can survive for forty days and works like the real thing – using a 3D printer.

The mini-livers, made by California-based medical research company Organvo, are just half a millimetre deep and four millimetres wide but can perform most of the functions that a real liver can.

The printer builds up 20 layers of hepatocytes cells, which carry out liver functions, along with two major types of liver cell. It also adds cells from the lining of a blood vessel. This allows the liver cells to receive nutrients and oxygen.

The most recent liver created survived for 40 days in the lab, which might not seem very long as human liver cells are replaced every 300 to 500 days, but the company’s previous mini-liver only survived for five days.

Keith Murphy, Organovo’s chief executive officer said: ‘In April we were able to show that liver function was retained in our 3D liver for over five days, and we have now demonstrated that our tissues perform consistently for at least 40 days, a significant improvement over the average 48 hour performance of 2D cultures.’

While research is in the early stages, scientists believe that future versions could be used for transplants.

I want a kidney. Grown from my own cells. I may see that happen before I shuttle off this mortal coil.

So, will they be able to “print” a patient a new hand or leg someday?

Between this, and that study where they transplanted memories from one rat to another, how long before it becomes possible to print a copy of a person, mind and all?

No. I have one good one. I sorta broke the other one and my spleen. I would like to have 2 functioning kidneys again. My spleen and I never talked, so I don't miss it.

Now print me a new replacement heart valve. The mechanical one ticks away like a clock (I actually get “your watch is loud” comments), but I’d rather have something derived from my own cells.

Wake me up when it makes more churches, more doctors and researchers doing real science, more fully intact American families, more motorbikes, more brains, more militiamen, more drug manufacturers, more American engineers and so on. Otherwise I could care less.

Seriously? You expect a printer to be a magical djinn? Isn’t that stretching it? Can’t you just be happy for those who may have their lives saved by this new technology? If the churches were doing their jobs, there’d be more than enough of them already. No “magic” can make up for Americans not taking “hard” math and science courses in high school and therefore not being prepared to study engineering in college. The government bureaucrats are the reason there are not more drug manufacturers, not some machine.

No, I thought it was clear it was meant partly in facetious and in part that I just can;t get myself to care about these things anymore until a true miracle happens. I’m too jaded to think of even this as an actual miracle, (yes I know, I have severe problems, hopefully I can overcome them and not let them get me committed or killed).

The strategy will probably be to grow an entire new heart from your cells.

There’s a commercial running for a new show with James Woods. He comments that in 100 years, we may be immortal. Well, I don’t know about immortal, but there seems to be no end to what these 3D printers can do. Imagine if everyone who needs one can get a kidney, a heart, a liver, or a lung? A new hand after an accident? Amazing, and apparently, not unlikely.

They are working on it, but they haven't been able to print her with a bikini on. Sorry.

I have to believe that they’re using the term, 3D printer, in a way different from that which we’re accustomed to. I can’t imagine that it’s possible to make infinitely complex human cells from inorganic materials. Maybe these are nano machines.

They are using the term 3D printer in a perfectly acceptable way. In this case, the 'ink' that the printer uses is the patient's own cells, grown in culture, and positioned by the printer to form the organ that is desired.

Just like a printer uses pre-made plastic to print a kewpie doll, the 'ink' has to be prepared first.

Only 40 days? That’s not much bang for the buck.
