Joris Peels lately wrote about UT Southwestern Medical Heart’s (UTSW’s) award of a $25 million grant from the Superior Analysis Initiatives Company for Well being (ARPA-H), for a challenge looking for to allow 3D printed livers made utilizing sufferers’ personal stem cells. A part of the U.S. Division of Well being and People Providers (HHS), ARPA-H was established by Congress in early 2022, modeled as a “DARPA for medical analysis”.
UTSW’s funding got here from ARPA-H’s Customized Regenerative Immunocompetent Nanotechnology Tissue (PRINT) program, first introduced in early 2024, with the awardees introduced on January 12. Along with UTSW’s challenge, ARPA-H additionally awarded PRINT funding to 4 different educational establishments throughout the U.S.: Carnegie Mellon, Wake Forest, Harvard’s Wyss Institute, and the College of California San Diego (UCSD).
Notably, all the initiatives concentrate on bioprinted livers apart from the challenge on the Wake Forest Institute for Regenerative Medication (WFIRM), which facilities round kidneys. WFIRM, in the meantime, has demonstrated its personal success with liver bioprinting, as nicely, together with an experiment that started in 2024, by which WFIRM despatched liver tissues and bioprinting gear to the Worldwide House Station (ISS). WFIRM adopted up on that preliminary challenge with one other ISS experiment that started final August.
As Vanesa Listek wrote in her Daring AM article on the unique WFIRM ISS experiment, “The liver is a very difficult organ to duplicate resulting from its massive dimension, complicated construction, and in depth vascular community,” which is without doubt one of the causes that analysis organizations are prioritizing the liver, amongst all of the doable pathways for bioprinting R&D. Moreover, the newest technological advances in modeling livers have led to enhancements in addressing exactly these challenges, suggesting that now could be the time when doubling down on elevated funding efforts may make a significant affect.
Above all, the prioritization that ARPA-H is giving to each bioprinted livers and bioprinted kidneys comes right down to the truth that these are merely within the scarcest provide for sufferers needing donor organs. The researchers pushing bioprinting ahead view it as an particularly promising choice largely owing to the possiblities for personalised medication.
At UCSD, for example, the analysis crew led by Professor Shaochen Chen will work with Allele Biotechnology, a San Diego firm “with experience in personalised stem cell technology applied sciences”, in direction of the purpose of printing a life-size, transplantable liver. The WFIRM kidney challenge will use patient-specific stem cells to develop “vascularized kidney tissue that augments renal operate in sufferers affected by kidney illness”.

Whereas the time-horizons for bioprinting analysis are, naturally, fairly lengthy, and the ARPA-H PRINT funding timeline spans 5 years, the awardees are simply as involved with commercialization as they’re with pure R&D. Professor Chen has beforehand based a startup, now known as CELLINK, a part of Sweden’s BICO Group, and an specific purpose of the WFIRM challenge is to make their kidney printing course of inexpensive, along with technologically possible.
In a press launch about Wake Forest’s ARPA-H PRINT award to develop inexpensive bioprinted kidney tissue, Dr. James Yoo, co-principal investigator and Chief Operations Program Officer at WFIRM, stated, “Our challenge will combine a wide range of processes and applied sciences, together with cell manufacturing, bioprinters and bioinks, and bioreactors, into an end-to-end workflow that produces clinical-grade, useful kidney tissue comprised of all main renal cell sorts.”
In a press launch about UCSD’s challenge aiming to develop a patient-specific, bioprinted liver, Gabriel Schnickel, professor of surgical procedure at UC San Diego College of Medication and co-investigator on the challenge, stated, “For many years, the transplant neighborhood has dreamed of a future the place the destiny of 1000’s of sufferers every year is not decided by the shortage of donor organs.This work has the potential to essentially change numerous lives by transferring that imaginative and prescient from aspiration to actuality.”
This isn’t a context the place one would usually consider 3D printing’s capacity to allow “mass customization”, however that’s an additive manufacturing (AM) benefit that the medical sector has already been efficiently leveraging for a few years, throughout a wide range of use-cases, so it’s finally fairly becoming. That the researchers concerned are discussing the commercialization of the related applied sciences is clearly thrilling to the extent that such commercialization would certainly enhance so many lives, however it’s additionally thrilling as a result of in the event that they’re speaking about it, they have to imagine that the truth isn’t so far-off.
After all, “not so far-off” within the medical sector nonetheless implies a quite prolonged course of, and the overall consensus appears to be that if bioprinted organs do sometime make it to medical trials, it gained’t occur till at the very least 2035. That’s an extended sufficient time from the current to appear just like the form of goal that can at all times simply hold getting pushed again. However, I feel that concerted efforts like what ARPA-H is doing, which is sustaining a real neighborhood of researchers fascinated about, supportive of, and educated concerning the subject, are the kind of motion that motivates everybody concerned to work in direction of a particular end line.
Regardless, as I’ve famous with equally moonshot targets like nuclear fusion, any knowledge that outcomes from the R&D makes the trouble worthwhile, whether or not or not the scientific neighborhood reaches the precise end-goal it has got down to obtain from the start. Particularly in the case of medical analysis, all info gained alongside the way in which is a win.
If the U.S. does handle to by some means succeed at reshoring, I feel the best chances are that it’ll primarily manifest in industries like this one, the place the U.S.’s capability for scale can really meet the duty at-hand, and the place the American historical past of biotech breakthroughs offers the panorama with a disproportionately advantageous start line. It will be extraordinarily troublesome for the U.S. to ever regain its standing as a significant shopper electronics powerhouse, but when bioprinted organs ever change into commercially scalable, it’s simple to ascertain the U.S. being a pacesetter out there.

This photograph demonstrates the evolution of Chen’s 3D bioprinting expertise from a proof-of-concept instrument to a business system that will probably be used as a part of the brand new ARPA-H-funded challenge.
