UK scientists use 3D printer to print human stem cells
Sure, 3D printing is cool and wonderful, and even can make awesome three-dimensional business cards. But can it save your life?

Well, perhaps.

Six scientists in the UK and Scotland have successfully printed human stem cells with a “valve-based cell printer” that uses bio-inks to fabricate groups of viable stem cells that retain their ability to become any type of cell in your body.

Stem cells are valued by biological scientists for research because they are “pluripotent:” they can develop into almost anything a human body needs such as skin cells, muscle tissue, or internal organs. But collecting and using them has been a controversial process, as one source for stems cells has been embryonic tissue harvested after abortions. And using them inside the human body has been difficult.

This new process essentially bio-fabricates usable conglomerations of human stem cells by printing bio-ink, made up of a number of organic components including HEK293 (human embryonic kidney) via a valve-based printer with very fine nanoliter capacity (an ounce of liquid contains 29,573,529 nanoliters). The nozzle of the valve-based printer that they used is only .002 inches wide.

Between 70 and 95 percent of the cells survived past 72 hours, and three days after, the cells tested positive for pluripotency, and seemed to be growing.

are we crossing lines we shouldn't cross now?

before long, natural birth will be outlawed, and only perfect copies, with perfect, obedient brains, printed out to order, will be allowed.

Not possible. Our medical science is 20 years behind the mighty US according to some on here.

Cool, they should let me print sperm so that I don't have to cum on my girlfriend anymore.

Nobody has the moral authority to control another person unless the first person has violated the first person. Those who do are called tyrants, either petty or grand.

Either way, they are to be despised and shunned. Variety and tolerance are the essence of humanity. I for one, will continue to impregnate girls with my superior sperm to improve the human race, but primarily because it feels good. Fuck anyone that tries to stop me. If others want to print their kids, so be it.

But how on Earth can a 3D printer duplicate the relevant DNA helix in the stemcell, or am I missing the point here ?

Flip side of this is this could provide an infinate amount of organs without the need for donnors. Science isn't good or bad, it's all in the application.
I don't think so,
he's up there with the others laying low,
vying with those who you've traded your life to to bless your soul,
