Researchers 3D-Print Heart From Human Patient's Cells
Researchers have 3D-printed a heart using a patient's cells, providing hope that the technique could be used to heal hearts or engineer new ones for transplants. "This is the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers," Professor Tal Dvir of Tel Aviv University's School of Molecular Cell Biology and Biotechnology said in a statement. Dvir is senior author of the research, published Monday in the journal Advanced Science. CNN reports: The process of printing the heart involved a biopsy of the fatty tissue that surrounds abdominal organs. Researchers separated the cells in the tissue from the rest of the contents, namely the extracellular matrix linking the cells. The cells were reprogrammed to become stem cells with the ability to differentiate into heart cells; the matrix was processed into a personalized hydrogel that served as the printing "ink."
The cells and hydrogel were first used to create heart patches with blood vessels and, from there, an entire heart. Next, the researchers plan to train the hearts to behave like hearts, Dvir explained. "The cells need to form a pumping ability; they can currently contract, but we need them to work together." If researchers are successful, they plan to transplant the 3D-printed heart in animal models and, after that, humans.

"If researchers are successful, they plan to transplant the 3D-printed heart in animal models and, after that, humans." Yeah or you could perfect it first, whichever.

So how long until they can 3D print a new moral compass for Bibi and a functioning brain for Trump? ... I suppose it will take a little longer before they can 3D print a soul for Putin.
Invent a sturdy sustainable way to hook up the brain to a computer already! (Maybe 3d-print organic connectors for the nerves?)
I want my ass to be 40% titanium!
This sounds like pure magic.
Any sufficiently advanced technology is indistinguishable from magic.

Now that we've helped Tin Man, maybe there is hope for President Scarecrow. ;)
Anons need not reply. Questions end with a question mark.
I see they haven't figured out how to print nerves yet.
After I wrote that sentence, I thought, how the hell does a heart transplant work since all the nerves had been cut. Apparently, the nerves degenerate immediately and the heart just runs on autopilot. They can't feel angina or other heart problems.
Just about 70% will eventually see new nerve growth however over a long period of time.
So yeah, they have to learn to print nerves unless they intend this to be bio-mechanical in some way.
The article I read after writing the initial sentence, it's a bit out of most of our fields, but is still fairly easy to interpret. I found it a fascinating read on a subject I have only passing familiarity with. (Once trained as a Medical Assistant. Then Hillary Clinton, the day Bill was elected said "health care reform." No one knew what it would entail, and the jobs dried up for about two years and I became a mechanic instead. My tale of woe for your entertainment)

Donald Trump, on a crusade to make Nixon look respectable
No, that was a Sanders supporter that decided shooting politicians was acceptable.
Its a left-wing thing, which the DNC is also currently supporting anti-Semitism and a KKK member, so they are much more Nazi like.
But if it isn't useful for anything, honestly: who cares? Research didn't used to be about scientists impressing themselves. :/
Am I missing something or has all the major stem cell breakthroughs been with Adult Stem Cell (from patient's own body) instead of Embryonic stem cells? Hmm. I wonder how that impacts the political discussion on that topic.

Some drink at the fountain of knowledge. Others just gargle.
I sincerely hope that all those that advocate for the antisemitic BDS movement never get to benefit from these, and other potentially life saving breakthroughs that have originated in Israel.
I am pretty sure the editors just copy/pasted the broken link from the CNN article. Obviously, that's a wrongheaded way of doing... editing.

"...they plan to transplant the 3D-printed heart in animal models and, after that, humans."
After the heart has been in an animal model, I don't think I would want it anymore. But that's just me...
(Sorry for the lame joke.)
