Harvard Researchers Print World's First Heart-On-A-Chip (gizmodo.com)

Posted by BeauHD on from the integrated-sensing dept.

Harvard University researchers have successfully 3D printed the first heart-on-a-chip with integrated sensors that are capable of measuring the beating of the heart. Gizmodo reports: The printed organ is made of synthetic material designed to mimic the structure and function of native tissue. It is not designed to replace failing human organs, but it can be used for scientific studies, something that is expected to rapidly increase research on new medicine. The medical breakthrough may also allow scientists to rapidly design organs-on-chips to match specific disease properties or even a patient's cells. Organs-on-chips, also known by the more technical name microphysiological systems, replicate the structure and function of living human organs. Each is made of a translucent, flexible polymer that lets scientists replicate biological environments of living organs. The chips are also clear so that the scientists can see an inner-working into how the organs work. A large part of the breakthrough was actually developing six different printable inks capable of integrating sensors within the tissue being printed. In one continuous printing process, the team 3D printed materials into a heart-on-a-chip with integrated sensors. The sensors were capable of measuring the beating of the heart. The new study has been published today in Nature Materials.

    Hmm .. OK it has been known for like over a decade at least how to make heart tissue. In fact it took me a while to follow the known protocol properly enough where I would *not* to make beating heart muscle cells from fibroblasts (skin cells). That was a few years ago.

    This isn't exactly new. Heart tissue is easy to grow and already used for disease modeling. Call me when they make something that is structurally a heart. We've had heart tissue in hydrogels and various other materials since the 1980s and heart tissue on sheets for maybe 20 years for drug testing. The novelty here is that it's on chip and optimal for drug testing?

    "Heart-on-a-Chip"

    Hmm, must be for reallllly tiny people I guess. I actually find the summaries constant and odd use of that phrase to be confusing and seemingly inconsistent with what they seem to be describing. Sounds like they 3D printed some sort of artificial heart but what the heck does "on a chip" mean in that context?
