03/29/17 - John Bischof & IEM Colleagues Achieve Breakthrough in Quest to Preserve Organs for Transplantation

Dr. John C. Bischof, IEM Associate Director for Development, and Professor of Mechanical and Biomedical Engineering, along with his IEM colleagues, have successfully demonstrated a method to safely warm vitrified tissue, a major step toward cryopreservation of human tissues and organs for transplantation. A barrier to preserving large tissues and organs by cooling (or vitrification) is that the tissue crystalizes and can also crack during the warming process, damaging the tissue. As reported by the Associated Press, Dr. Bischof's team has overcome this by using iron oxide nanoparticles that, when heated by radiofrequency fields, allow for a uniform and rapid warming of the vitrified tissue. This method, known as nanowarming, could eventually be applied to entire organs, and ultimately result in helping to meet tissue and organ demand of those needing transplants. However, this will require more years of research to achieve. "We are cautiously optimistic that we're going to be able to get into a kidney or maybe a heart. But we are not, in any way, declaring victory here," says Dr. Bischof. Other IEM members on Dr. Bischof's team included IEM Executive Committee Member Dr. Christy L. Haynes, Professor and Vice Chair, Department of Chemistry; Dr. Alex Fok, Professor of Restorative Sciences; and Dr. Michael Garwood, Professor of Radiology-CMRR. The research has been published in Science Translational Medicine.


7-31-2017 - IEM-Affiliated Centers Play Key Roles in Utilizing Virtual Reality & 3D Printing to Prepare for Successful Surgery to Separate Conjoined Twins

The IEM-Affiliated Earl E. Bakken Medical Devices Center, Visible Heart Lab, and 3D Printing Core all played key roles in the preparation for a very challenging, but successful surgery to separate twin sisters conjoined at their hearts and livers. These capabilities were required due to the unique aspects of the twins' anatomy and high risks of the procedure. The twins' condition prior to surgery was "extraordinarily shocking," according to IEM Member Dr. Daniel A. Saltzman, Professor of Pediatric Surgery, who performed the operation with his team at the University's Masonic Children's hospital. Dr. Saltzman informed the parents that, as a result of the procedure, they "could lose one or both twins."
The members of Dr. Saltzman's team planned key aspects of the surgery by utilizing the Medical Devices Center's 3D Virtual Prototyping system to visualize both virtual and printed models of the twins' hearts; these were generated from CT and MR images by Alex Mattson, a Biomedical Engineering Ph.D. Candidate within the Visible Heart Lab, and Bethany Tourek, a Mechanical Engineering Ph.D. Candidate within the Medical Devices Center. Mattson also helped Pediatric Cardiologist Dr. Matthew Ambrose utilize both the Medical Devices Center's 3D Virtual Prototyping system and the Visible Heart Lab's 3D Visualization System, which the physician used to perform a virtual walk-through of the twins' anatomy. Dr. Anthony Azakie, Chief of Pediatric Cardiac Surgery, who separated and repaired the twins' hearts, asked Mattson to scrub in on the case based on his knowledge of the anatomy. The Visible Heart Lab's component of the IEM 3D Printing Core was also utilized to print numerous detailed 3D models, some of which were hand painted by Mattson to show relative degrees of blood oxygenation with these conjoined heart anatomies.
What the surgical team members learned by using these tools helped them to better-understand the twins' anatomy and led to a change in the surgical plan, in what ultimately resulted in a successful outcome. And, according to the Washington Post, this may have been the first time that virtual reality has been used to prepare for surgery to separate twins conjoined at their hearts. "It felt like I was working in the future," says Dr. Saltzman. "It was extraordinarily exhilarating."

11-30-2017 - Artificial Blood Vessel Developed by Bob Tranquillo Advancing Toward Clinical Application

IEM Member Dr. Robert T. Tranquillo, Professor and Head of the Department of Biomedical Engineering, has demonstrated in a pre-clinical study the effectiveness of a decellularized cell-grown tissue tube that can potentially be used as an alternative to a synthetic tube for hemodialysis patients. In research that was published in Science Translational Medicine, "off-the-shelf" decellularized grafts were implanted into baboons, then recellularized over a 6 month period with the host's cells, after which the biologically-engineered grafts were still strong despite repeated puncture with a dialysis needle and did not show signs of immune rejection. "So what makes our material different is the ability for it to become cellularized from the patient's own cells and become a living tissue so it can heal," says Dr. Tranquillo. This healing ability makes the grafts superior to synthetic grafts, which have a greater risk of clotting, infection and immune rejection. "We have enough evidence that this can work in a patient without posing an adverse risk. That is a big milestone for us to get into a clinic," says Dr. Tranquillo


7-31-2017 - John Bischof & Colleagues Develop Advanced Cryopreservation Tool that Utilizes Lasers & Gold Nanoparticles

Dr. John C. Bischof, IEM Associate Director for Development, and Professor of Mechanical and Biomedical Engineering, and his colleagues, have developed an advanced tool that utilizes lasers and gold nanoparticles for the cryopreservation of tissue. The research, entitled "Gold Nanorod Induced Warming of Embryos from the Cryogenic State Enhances Viability," was published in the journal ACS Nano. "Lasers have the exciting ability to act like a 'light switch' that can turn biological activity on and off within gold nanoparticle laden biomaterials," says Dr. Bischof, who was the senior author of the study. "In this case, by careful engineering and deployment of gold nanoparticles within a cryogenically stored and biological inactive embryo, we can use a laser pulse to quickly warm the embryo back to ambient temperatures and switch biological activity, and therefore life, back on."

05-22-2017- Research Led by David Odde Increases Understanding of How Cancer Cells Spread

IEM Executive Committee Member Dr. David J. Odde, Professor of Biomedical Engineering, led a study that has increased the understanding of how cancer cells use their ability to assess their surroundings to migrate through those environments. The research, which was partly funded by IEM and published in Nature Communications, could eventually lead to the development of therapies that would inhibit the spread of cancer. Dr. Odde says that "Cells are a little like the storybook character Goldilocks. They don't like their environment too hard or too soft--it needs to be just right or they won't move well," and that "If we can trick cancer cells into believing it is not a good environment for migration, we can limit the cancer cells spreading in the body." A distinguishing aspect of the research, according to Dr. Odde, was its approach of combining math and physics to build models that were then tested experimentally, noting that the research team "brought an engineering approach to an important medical problem."

Building upon technology Dr. He developed for mind-controlled drones, the robotic arm system is a big step toward a future of medical applications that could range from rehabilitating stroke patients to helping paralyzed patients regain the ability to perform basic tasks in their everyday lives. The paper was published in Scientific Reports, a Nature research journal.


09/30/16 - Jerry Vitek and Colleagues Awarded $9 Million Udall Center of Excellence in Parkinson's Disease Research

A recently-awarded Udall Center of Excellence in Parkinson's Disease Research at the University of Minnesota will be led by IEM member Dr. Jerrold L. Vitek, Professor and Chair of the Department of Neurology. It is one of 9 such centers funded in the U.S., and will be supported with more than $9 Million of NIH funding over 5 years, with its research theme being "Circuit-based deep brain stimulation for Parkinson's disease." Dr. Vitek, who will serve as the center's Principal Investigator, says that the University of Minnesota has "a world-class multidisciplinary team to treat patients with Parkinson's disease, and because of our significant experience and expertise we are able to take on this complex and often debilitating movement disorder with a goal of improving patient's lives." Legislative support through the MnDRIVE Brain Conditions initiative played a key role in securing the center award for the University, according to Dr. Vitek. Two IEM Seed Group Grants also helped to facilitate the early development of the center's research.

08/29/16 - David Odde and Colleagues Awarded an $8.2 Million NIH Grant for New Cancer Research Center; IEM Seed Grants Played Early Role

IEM Executive Committee Member Dr. David J. Odde, Professor of Biomedical Engineering, and his team, have been awarded a 5-year, $8.2 Million NIH Physical Sciences in Oncology Center (PSOC) grant from the National Cancer Institute. The development of the center project was supported by two IEM Group Grants since 2013. Dr. Odde is serving as the Project Leader (contact PI) for this Center for Modeling Tumor Cell Migration Mechanics, which is one of a nationwide network of 10 PSOC's. In addition to Dr. Odde, other key leaders include IEM Member Dr. David A. Largaespada (multiple PI), Professor, Department of Cell Biology and Development Genetics, of the Masonic Cancer Center, IEM Member Dr. Paolo Provenzano (core PI), Assistant Professor of Biomedical Engineering, and Dr. Steven Rosenfeld (multiple PI), of the Cleveland Clinic. The center will include a team of biomedical engineers, cancer biologists, surgeons and oncologists from the University of Minnesota, who will collaborate with both the Cleveland Clinic and Mayo Clinic.

While common approaches to fighting cancer involve the attacking of cancer cells, the new center will instead explore how cancer cells can be prevented from migrating and ultimately metastasizing and invading vital organs, which are the primary causes of cancer deaths. The center will perform "integrated modeling and experiments to investigate the molecular mechanics of cell migration and how the tumor microenvironment regulates disease progression as a function of the underlying carcinoma genetics."
