New Minnesota-based medical device company focuses on biological medical devices manufactured using perfusion decellularization technology

Minneapolis, Minn. (July 1, 2019) – Reprise Biomedical, Inc., a Minnesota-based startup focused on commercializing biological medical devices manufactured using a proprietary perfusion decellularization technology, has successfully completed a $12.5 million private placement and commenced operations as a spin-off from Miromatrix Medical Inc.

Through the spin-off, Miromatrix transferred to Reprise two existing FDA 510(k) cleared, commercially available medical devices – MIROMESH® and MIRODERM® -- as well as all acellular medical devices in development. After the spin-off, Miromatrix will continue its primary focus on the development of transplantable organs to address the chronic organ shortage.

MIROMESH is a biological mesh derived from perfusion decelluarized porcine liver, compressed and cut into a variety of sizes suited for hernia repair applications. MIRODERM is also derived from decellularized porcine liver and further processed for use in the management of wounds including diabetic foot ulcers, venous ulcers, pressure ulcers, and surgical and trauma wounds. Combined, these two medical devices generated net sales of $1.75 million in 2018 and address U.S. market opportunities that Reprise estimates exceeds $1 billion.

Reprise is led by Carrie Powers, who previously served as Senior Vice President of Marketing at Vascular Solutions, Inc., a Maple Grove-based medical device company that developed and launched over 100 new medical devices before it was sold to Teleflex in 2017 for $1 billion. The Board of Directors of Reprise includes Ron Eibensteiner, President of Wyncrest Capital; Erwin Kelen, venture capitalist and founder of Kelen Ventures; Jeff Ross, CEO of Miromatrix; and Howard Root, co-founder and former CEO of Vascular Solutions, as Chairman.

Healthline: Scientists Hope to Grow Bioengineered Livers for Transplants

hl-logo.v1.20171218143242.png

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.
