Nortis’ versatile microfluidic technology enables researchers to engineer a wide range of three-dimensional tissue microenvironments.


About the size of a credit card, Nortis' unique microfluidic chips can be used to grow tissue microenvironments by seeding cells into tubular voids within extracellular matrix gels. The chip design offers the flexibility to generate a variety of tissue architectures based on cell types and matrix materials selected.

Small, portable perfusion platforms house the disposable chips and supporting media and collection reservoirs. Three-shelved docking stations that reside in a standard tissue culture incubator increase experimental throughput and flexibility by enabling up to twelve independent experiments to be run at a time. Perfusion through both the tissue lumen and surrounding extralumenal space allow physico-chemical gradients to be created and perfusion fluids and cells to be collected for downstream analysis. Each docking station shelf can easily be removed and the small perfusion platform/chip assemblies accommodate easy transport between the cell culture incubator, laminar flow hood, and microscope stage.


A key element of Nortis' technology is the ability to subject the tissues to fluid flow directly through the vessel lumen, which enables:

  • Creation of vasculature and other tubular tissues
  • Delivery of test compounds via the perfusate
  • Exposure to shear and flow forces that are present in the body
  • Independent perfusion through the vessel and matrix compartments

The entire Nortis system fits inside a standard tissue culture incubator.

  • University of Washington & Kidney Research Institute Kidney-on-a-chip will travel to International Space Station

    UW Pharmacy and UW Medicine team to study how weightlessness accelerates kidney damage

    In as early as 2018, a rocket carrying a payload that includes 24 microfluidic chips about the size of credit cards will transport an extraordinary University of Washington kidney research project to the International Space Station.

    Researchers from UW School of Pharmacy and UW Medicine collaborate to advance kidney care (from left to right: Dr. Phavan Bhatraju, Pulmonary Fellow; Ranita Patel, Pediatric Nephrology Fellow; Elijah Weber, newly-minted PhD, Pharmaceutics; Kirk Van Ness, Research Scientist, Pharmaceutics; Christina Kim, Undergraduate Researcher; and Ed Kelly, Associate Professor of Pharmaceutics and Kidney Research Institute Investigator)

    University of Washington School of Pharmacy and UW Medicine researchers, in collaboration with the Seattle-based organ-on-a-chip company, Nortis, have been developing the “kidney-on-a chip” as a laboratory model for understanding how this organ is affected by drugs, toxins and environmental exposures. The chips contain a central chamber lined with live kidney cells.

    This novel space medicine project is an attempt to understand how microgravity and other factors worsen kidney health. Researchers hope to use these discoveries to design better treatments for proteinuria (the presence of protein in the urine that signals possible kidney problems), osteoporosis (bone loss) and kidney stones on Earth.

    “Weightlessness is an accelerator,” said UW School of Pharmacy faculty member and Kidney Research Institute investigator Ed Kelly. “In the microgravity environment on the International Space Station, kidney problems are more common and develop in weeks or months, instead of decades. By studying the kidney on a chip after a few weeks in space, we expect to learn more about how osteoporosis, kidney stones and other kidney conditions develop, which may lead to breakthroughs in treatment and prevention.”

    The first phase of the project will be to launch chips that measure the effect weightlessness has on healthy kidney cells. The second phase will launch about 18 months later and will measure the effect of weightlessness on diseased kidney cells. Astronauts on the space station will monitor and maintain the chips and then return them to Earth after several weeks for the UW team to examine.

    A collaboration between UW School of Pharmacy, UW Medicine, Kidney Research Institute, and Nortis led to this advanced kidney-on-a-chip model designed for research on the International Space Station.


    A collaboration between UW School of Pharmacy, UW Medicine, Kidney Research Institute, and Nortis led to this advanced kidney-on-a-chip model specifically designed for research on the International Space Station.

    Jonathan Himmelfarb, of UW Medicine and director of the Kidney Research Institute, a collaboration between Northwest Kidney Centers and UW Medicine, along with researchers from the UW School of Pharmacy: Ken Thummel, Ed Kelly, and Cathy Yeung, have developed the kidney-on-a-chip system using technology developed by Nortis. The kidney chips contain a small sample of live human kidney cells to test how drugs will affect those cells. The system offers a safer, more accurate, less invasive means of testing drugs before they are tried in patients. Importantly, it will reduce the need for animal testing in drug discovery research.

    “Use of the human kidney on a chip here on Earth has already taught us a lot about kidney function and kidney diseases,” said Himmelfarb. “The opportunity to study how physical cues emanating from loss of gravitational forces affect kidney cellular function has the potential to improve the health of people living on Earth as well as prevent medical complications that astronauts experience from weightlessness.”

    The kidney is a critical organ in drug clearance. When healthy, your two kidneys work together to filter about 110 to 140 liters of blood and produce about 1 to 2 liters of urine every day. Dehydration or diseases like diabetes and high blood pressure impair kidney function and result in serious medical conditions including protein in the urine and kidney stones. The kidney also plays a critical role in the body’s ability to use Vitamin D to maintain strong bones; a decline in this function can result in a loss of bone health.

    A better understanding of the mechanics of basic kidney function could lead to improved treatments for patients fighting kidney conditions. Pharmaceutical scientists from the UW School of Pharmacy have significant knowledge on how drugs affect and are processed by the body. Their work in this area enhances the research done by UW Medicine and Kidney Research Institute clinicians.

    The Kidney on a Chip in Space Project will study effects of microgravity on the structure and function of the proximal and distal tubule microphysiological system. This model is used in laboratory studies to understand how the kidney clears drugs and how medications damage the kidney. In people, the kidney proximal and distal tubules are located in the nephron, which is the basic functional part of the kidney. They are both convoluted, but have different structures. The new chip project extends previous work on modeling a proximal tubule by adding a distal tubule.

    The UW School of Pharmacy, UW Medicine and Kidney Research Institute team have partnered with BioServe Space Technologies at the University of Colorado to work with engineers who specialize in developing scientific testing equipment for space launch. The four-year, $3 million grant (1 UG3 TR002178-01) was awarded by National Center for Advancing Translational Sciences (NCATS), part of the National Institutes of Health (NIH). The Center for the Advancement of Science in Space (CASIS), the organization tasked by NASA to manage the International Space Station U.S. National Laboratory, will contribute the space flight, time in station, and Space Station crew costs, for an in-kind total of $8 million.

    The official project kick off will be in late September at Cape Canaveral in Florida.

  • A pocket-size research revolution

    UW School of Pharmacy team's work could change the future of precision medicine and kidney research — with a device the size of a credit card.

    The Centers for Disease Control and Prevention estimates that while 15 percent of American adults have chronic kidney disease, most of them don’t even know it.

    Only when the disease is in its later stages — when it’s often too late for reversal — do more severe symptoms cause people to seek help, says Catherine Yeung, research assistant professor at the University of Washington School of Pharmacy.

    An inability to track the early stages of chronic kidney disease leaves researchers like Yeung at a loss for what early biological markers might look like. There’s also much to learn about how kidney problems affect the body’s ability to eliminate medications.

    At the School of Pharmacy, an interdisciplinary team is undertaking revolutionary work that could change the future of precision medicine and kidney research — all with a device the size of a credit card.

    It’s called kidney-on-a-chip. Inside its small frame are thousands of live kidney cells that can model the functions of a human kidney.

    A breakthrough in kidney research

    “Kidneys are part of the ‘holy trinity’ of drug clearance,” says Edward Kelly, associate professor at the School of Pharmacy and the lead investigator on the project. “The intestine is involved in absorption, the liver is involved in metabolism and the kidneys are involved in excretion,” meaning they help the body clear medication via urine.

    People with failing kidneys might not be able to process medications as efficiently as those with healthy kidneys. On top of that, there’s the possibility that certain medications could further compromise their kidneys. This is critical because — unlike the liver and other organs — the kidney lacks the ability to regenerate.

    That’s where the UW is focusing with kidney-on-a-chip.

    Working alongside Kelly and Yeung is Jonathan Himmelfarb, M.D., the Joseph W. Eschbach, M.D., Endowed Chair in Kidney Research at the UW School of Medicine and the internationally renowned director of the Kidney Research Institute, a collaborative effort between UW Medicine and Northwest Kidney Centers.

    With support from both the UW and Northwest Kidney Centers, team members brought their expertise together for the kidney-on-a-chip project. They have already begun testing various drugs, including antibiotics that are less harmful to kidneys. Instead of giving patients experimental treatments that may or may not work, “We could see the effects in kidney-on-a-chip before we test them in humans,” says Kelly.

    Kidney-on-a-chip heads to outer space

    But what if you could speed up the development of kidney disease? In 2018, the UW team is sending kidney-on-a-chip to the one place where time does speed up: outer space.

    Microgravity acts as an accelerant, so kidney problems that take decades to develop on Earth need only weeks or months on the International Space Station, where astronauts will study the chips over the course of a few weeks.

    Team member Kenneth Thummel, the Milo Gibaldi Endowed Chair in Pharmaceutics at the School of Pharmacy, has previous experience keeping astronauts healthy. With long-standing research interests in vitamin D metabolism and the regulation of mineral homeostasis, a key component of kidney function, Thummel was part of a special National Research Council committee that established guidelines for chemical exposure in spacecraft air and water.

    Bone loss is a major concern for astronauts, Kelly says. “That’s why astronauts exercise and employ other means to counter this issue when they’re in space. Kidneys synthesize the active form of vitamin D, which is necessary to maintain healthy bones, so we’ll be asking if kidney cells still perform that function in microgravity.”

    Sending the chips to the Space Station also stands to benefit another group of space travelers: the first Mars colonists.

    The current record for the most consecutive days in space is 438 — but in theory, Mars colonists would remain for decades. After studying chips on the Space Station, researchers might have a better idea of how to help the human body withstand the effects of spending so much time in a lower-gravity environment.

    For the researchers involved, kidney-on-a-chip might very well bring about changes in their lifetime, a rarity for big medical breakthroughs. This trailblazing science is made possible in large part by donors who support the Pharmaceutics Fund for Excellence, which invests in startup research projects like kidney-on-a-chip.

    “As a pharmacist, I’m very satisfied to be able to show people what we’re doing and where their research dollars are going,” says Yeung. “With kidney-on-a-chip, we have an actual chance to impact the lives of patients.”
