Miromatrix Awarded $1.9 Million NIH Grant to Advance the Development of a Bioengineered Liver


Miromatrix Inc., a Minnesota-based biotechnology company, was awarded a $1,970,000 Direct to Phase II Small Business Innovation Research (SBIR) grant from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the National Institutes of Health (NIH) to advance the development of a bioengineered transplantable liver to address the chronic shortage of transplantable livers.

Currently, liver transplantation is the only treatment for End-stage Liver Disease (ESLD), the 8th most frequent cause of death in the United States with over 40,000 deaths annually. Demand for transplantable donor livers continues to exceed the available supply; as a result, only half of the 13,000 wait-listed patients will receive transplants. Miromatrix’s approach to solving the shortage is to bioengineer a transplantable liver utilizing their proprietary perfusion decellularization and recellularization technology.

"We’re thrilled to receive support from the NIDDK and NIH along with additional affirmation of the groundbreaking work we're doing to develop fully functional transplantable livers and provide more options for the thousands of patients with liver failure who face an uncertain future,” says Dr. Jeff Ross, Miromatrix CEO. “Our mission is to eliminate the liver transplant waiting list and save thousands of lives. The support of this grant brings us one step closer to our goal.”

KARE 11: Kidney transplant alternative research gives transplant patients on the waiting list new hope

Researchers at Eden Prairie-based Miromatrix are leading the race to develop the first transplant alternatives.

Right now a Minnesota company is working to develop a kidney transplant alternative. It’s a one-of-a-kind solution to end the transplant waiting list as we know it. Using a breakthrough process developed at the University of Minnesota, Eden Prairie-based Miromatrix Medical Incorporated is creating transplantable human organs out of pig organs.

Dr. Jeff Ross, Miromatrix CEO, said Minnesota researchers are leading the regenerative medicine race. “We’re creating human organs out of discarded pig organs. We take what nature designed, a fully functioning liver, kidney or heart and with our patented technology, which was developed at the University of Minnesota, we remove all of the cells from the organ. What’s left is a ‘scaffold.’ All of the organ’s natural design and architecture remain. Then from the inside out, we seed or implant new, human cells back into it, ultimately creating a completely functional, transplantable organ that could save a life,” explained Dr. Ross.

Healthline: Scientists Hope to Grow Bioengineered Livers for Transplants


Healthline has published an article about our bioengineered liver project and our hopes to eliminate the liver transplant waiting list. 

“We remove all the cellular material from the liver, but the architecture is still there. We have a perfect architecture of the organ,” Ross, the chief executive officer of Minnesota-based Miromatrix Medical, told Healthline.
Having that scaffolding, or functional vasculature, overcomes what he says has been one of the major roadblocks in being able to engineer livers in the lab.

"Much further along, and less ethically fraught, is a technique in which decellularized pig organs act as a scaffold for human cells. A Minnesota-based company called Miromatrix Medical is working with Mayo Clinic researchers to develop this method. First, a mild detergent is pumped through the organ, washing away all cellular material. The remaining structure, composed mainly of collagen, is placed in a bioreactor, where it’s seeded with human cells."

LeapsMag was created by Leaps by Bayer, a new innovation initiative whose mission is to “aim for fundamental breakthroughs in the life sciences – ‘leaps’ that have the potential to change our world for the better.”  Leaps by Bayer holds the conviction that ‘fundamental breakthroughs’ are absolutely necessary to conquer the most demanding challenges facing humanity. And that these breakthroughs will only be made possible by those willing to take risks and do what many think can’t be done.

Miromatrix Presents Milestone on Engineering a Transplantable Kidney at Kidney Week 2017 in New Orleans

Kidney Week.png

Miromatrix will present its most recent bioengineered kidney milestone at Kidney Week 2017 hosted by the American Society of Nephrology (ASN) on October 31st through November 5th in New Orleans.  As we progress towards a bioengineered kidney we must demonstrate functional vasculature to be able to continuously perfuse blood.  We have been able to show that functional vasculature can be achieved by repopulating decellularized kidneys with human primary endothelial cells.

A poster, presented by Senthuran Atputhanathan B.S., describing this achievement entitled “Development of Functional Vasculature in Decellularized Whole Porcine Kidneys with Human Endothelial Cells” will be presented at the conference on November 3rd (Poster #FR-PO977).   Whole porcine kidneys were perfusion decellularized and human umbilical vein endothelial cells (HUVEC) and primary human epithelial cells (HRE) were perfused into the kidney graft’s vascular and tubular compartments respectively. Key metabolic parameters were monitored to assess cell proliferation and viability while whole organ culture was performed under continuous media perfusion.  Additionally, recellularized kidneys were introduced into blood loops using whole porcine blood to model in-vivo performance as functional vasculature assessments were performed.  Cellular engraftment and viability were measured by metabolic parameters including glucose consumption over 3 to 4 weeks (n=12) to achieve the desired level. These data were further corroborated by histological analysis of formalin fixed kidney sections demonstrating the presence of a single layer of engrafted cells on vascular and tubular compartments. Furthermore, cells positive for the endothelial cell marker CD31 were confined to the vascular compartment and cells positive for the epithelial cell marker e-cadherin were confined to the tubular compartment. Vascular functionality was characterized by blood loops and demonstrated long-term continuous perfusion of whole blood compared at physiological pressures compared to non-recellularized kidneys that demonstrated the lack of flow after a few minutes.  These results demonstrate the ability to generate a functional vasculature in our recellularized kidney grafts, a critical first step in the engineering of a fully bioengineered kidney.

“The progress represented in our revascularized kidneys is a tremendous milestone in our goal to bioengineer transplantable kidneys,” says Senthuran Atputhanathan, Miromatrix Kidney Scientist. “Our ability to demonstrate functional vasculature in these large animal kidney grafts is exciting as it enables us to continue to build upon our success by introducing additional functional kidney cells into our kidney grafts.”

Kidney Week is the world's premier nephrology meeting.  The conference showcases the latest scientific and medical advances and hosts engaging and provocative discussions with leading experts in the field of nephrology.
