Ms. S.H. shared this article, and it's another important signal that technologies are going to rapidly change the way that we look at the world, and the world of medicine in particular. In this case, as the title of this blog indicates, Russia has successfully 3D printed artificial mouse-thyroid glands, and successfully transplanted them in mice, with the successful restoration of thyroid function:
The experiment is outlined as follows in the article:
The thyroid glands in mice were first killed by a radioactive iodine injection, before the research team transplanted newly-printed organs into their subjects.
Three weeks into the experiment, the team, headed by Vladimir Mironov, observed “higher” levels of the hormone T4, which is responsible for growth and the metabolism, and measured higher body temperatures, Bulanova said.
After 11 weeks of monitoring the subjects’ 3D printed thyroid glands, they were fully functional with completely restored thyroid function.
“All in all we consider experiment to be successfully conducted because we managed to raise the level of hormone T4,” Bulanova said.
The 3D-printed organ consists of several types of tissues, and features blood vessels to substitute the thyroid gland of a living organism. The lab’s undertaking to transplant the thyroid first began in March 2015, when the organ was first printed using the Russian bio printer FABION.
In further experiments and in printing other organs, potentially human, researchers are planning to use undifferentiated stem cells taken from an adult organism, which are very similar to embryonary cells.
This is a major step, if you've been following the biological applications of three-D printing, for thus far we've read of the stories of various tissues being three-d printed, but whole organs which are then successfully transplanted to restore missing functions has not been achieved until now.
As the article itself notes, imagine the applications to a variety of function-restoration applications. It might, indeed, be possible to envision the application of such technologies and techniques to partial organs, save, the 3D printing of a heart valve from a patient's DNA, to replace malfunctioning valves. We've already seen such partial appplications in the growth of retinas for eyes. Imagine, too, the applications of such technologies to repair eye function, or even replace entire eyes themselves, to restore sight to the blind. Take it a step further: imagine the growth of essential organs such as the liver, or kidneys, two organs that are often high on transplant waiting lists, and absolutely vital and essential to the proper function of the body.
The danger of transplants has, of course, always been that of the rejection of the transplanted organ by the host's body, a danger that would, the reasoning goes, disappear entirely if one could literally grow and 3d print the spare part from the patient's own DNA. IMagine, too, the benefit of such technologies to first responders in medical emergencies.
In a certain sense, all of this imagination has, until now, been precisely that: imagination, the extrapolation of possibilities from present techniques and technologies. But now, medical scientists and technicians have actually taken that first step, by printing an artificial organ, in its entirety, and transplanting it successfully in mice to restore lost (thyroid) organ function. And with this step, another problem disappears, and new problems emerge, for many people object, on religious or other grounds, to organ transplants from other humans. But with the additive manufacturing process wedded to genetic technologies, such ethical concerns could indeed be headed to oblivion, and new ethical concerns are raised: if body parts can essentially be replaced with new ones, made from one's own DNA, as they wear out, the prospects of the transhumanists' quest for virtual immortality open up
In short, the Russian success here is a huge step.
And only the first of many more.
And it prompts a high octane speculation and question. Many readers here have noted the unusual longevity of certain members of the "elite". Many have also commented upon the idea that the technologies that are being revealed publicly possibly lag several years or even decades behind what might be privately and secretly accomplished. Could it be, therefore, that such capabilities as the Russians have publicly disclosed have already been developed in secret, across the whole range of human medicine and biology, and already been covertly applied? If this type of technology is going to change the world and the way we look at it, might we, indeed, be looking at its present application when we consider the longevity of certain members of the elite? Think only of Queen Elizabeth II here. Since her sixties, she has barely aged in her appearance, and she is now 89 years old. Prince Philip is now 94 years old, and while he looks old, he looks more like he is in his late 70s than middle 90s.
Well, perhaps. But after all, there is no reason to suspect or conclude that the "black projects" world has simply to do with advanced physics and physical technologies.
See you on the flip side...
