Pitt researchers receive $1.54 million NIH grant to facilitate fabrication of vascular grafts with artificial stem cells

Bioengineering, Chemical & Petroleum

PITTSBURGH (June 29, 2016) … The National Institutes of Health have awarded David Vorp, the William Kepler Whiteford Professor of Bioengineering and Associate Dean for Research of the Swanson School of Engineering at Pitt, and colleagues with a grant worth more than $1.54 million to fund their study investigating artificial stem cells in the development of engineered vascular grafts. Some current regenerative medicine approaches use mesenchymal stem cells (MSCs) harvested from the patient to help rebuild or repair damaged or diseased tissues. Dr. Vorp and his team have pioneered the use of MSCs in the development of tissue-engineered vascular grafts (TEVGs), which may be effective in small diameter arterial bypass procedures or arteriovenous access for dialysis. However, MSCs taken from patients at high risk for cardiovascular disease, such as the elderly and diabetics, may be dysfunctional. Furthermore, the use of harvested cells that require extended culture expansion also runs the risk of cellular contamination or transformation, as well as high costs and substantial waiting time before a graft can be made and implanted. “Fully functional human MSCs secrete a host of biochemicals, including those that prevent blood clotting and those that ‘call’ into the TEVGs important cells from the host, such as inflammatory cells, smooth muscle cells and endothelial cells,” said Vorp. “We have found that MSCs from diabetics, for example, are relatively ineffective in yielding a successful TEVG compared to MSCs from non-diabetics.  Considering that diabetics make up a large proportion of patients who need bypass grafts, we needed to find an alternative means to achieve our goal for this significant population.”   To answer this challenge, the research team has developed artificial stem cells (artMSCs) that are created by encapsulating the veritable cocktail of biochemicals secreted by normally functioning MSCs in culture into biodegradable microspheres that are similar in size to actual MSCs. “By ‘tuning’ or adjusting the degradation rate of the microspheres, we can replicate the release of these biochemicals by real, fully-functional MSCs,” said Vorp. He and his colleagues will then seed the artMSCs into porous, tubular scaffolds and implant them in a rat model as they have done with MSCs in fabricating TEVGs. The study, entitled “Artificial Stem Cells for Vascular Tissue Engineering,” aims to accelerate the clinical translation of the team’s TEVG technology. This will be achieved, according to Vorp, “both by making the technology applicable to all patients – even those with dysfunctional MSCs – and by reducing the regulatory barriers associated with the need for culture-expanding cells to the numbers necessary to fabricate a TEVG.” Vorp is joined on this study by Pitt colleagues Steven Little, the William Kepler Whiteford Professor and Chair of Chemical Engineering; William Wagner, Professor of Surgery and Director of the McGowan Institute for Regenerative Medicine; Morgan Fedorchak, Assistant Professor of Opthalmology; and Justin Weinbaum, Research Assistant Professor of Bioengineering. ###

NIH grant to support continuation of joint regenerative medicine program between Pitt and Carnegie Mellon

Bioengineering, Civil & Environmental, MEMS

PITTSBURGH (May 18, 2016) … With the goal of advancing regenerative medicine therapies, a partnership between the University of Pittsburgh and Carnegie Mellon University has received a five-year, $1.4 million grant from the National Institutes of Health (NIH) to provide training in biomechanical engineering principles and biology to students pursuing a doctoral degree in bioengineering. “Training in Biomechanics in Regenerative Medicine” (BiRM) is funded through the NIH’s National Institute of Biomedical Imaging and Bioengineering’s T32 grant program. The program director and principal investigator is Savio L-Y. Woo, PhD, D.Sc., D.Eng., Distinguished University Professor of Bioengineering in the University of Pittsburgh’s Swanson School of Engineering and the founder and director of the Musculoskeletal Research Center (MSRC) at Pitt. He is joined by co-investigators, James Antaki, PhD, Professor of Biomedical Engineering at Carnegie Mellon University, and David Vorp, PhD, Associate Dean for Research and the William Kepler Whiteford Professor of Bioengineering at the Swanson School. According to Drs. Woo, Antaki and Vorp, regenerative medicine uses methods including tissue engineering, cellular therapies, biosurgery and artificial and biohybrid organ devices, to address tissue/organ insufficiency. Yet despite several early successes, bioengineers have faced challenges in repairing or replacing tissues that serve a predominantly biomechanical function. The Pitt-CMU program aims to bridge that gap by training students in both biomechanical engineering principles and biology. “Regenerative medicine is at a critical juncture in its evolution, and Pitt and CMU are uniquely positioned to create an interdisciplinary program to benefit our graduate students,” Dr. Woo said. “Since the BiRM program is not central to any one department, it provides students with both fundamental knowledge and problem-solving skills as well as inter-departmental didactic and research experiences, and specialized training in areas such as innovation and entrepreneurship.” To develop these diverse skills, BiRM incorporates faculty from Pitt’s departments of Bioengineering, Civil and Environmental Engineering, and Mechanical Engineering and Materials Science in the Swanson School of Engineering; Carnegie Mellon’s departments of Biomedical Engineering and Mechanical Engineering; and Pitt’s Schools of the Health Sciences, including the School of Dental Medicine, Department of Orthopedic Surgery, and Division of Cardiology. BiRM faculty also have appointments in the joint Pitt-CMU Clinical and Translational Sciences Institute and the McGowan Institute for Regenerative Medicine. Dr. Woo noted that during BiRM's first two cohorts, 30 students gained a solid foundation for productive and independent careers in academia, industry, and medicine spanning a wide range of physiological systems including orthopedics, vascular surgery, dentistry, urology, and others. Over the next five years, the Pitt-CMU partnership seeks to sponsor six pre-doctoral fellowships per year corresponding to approximately 14 additional fellowships over the course of the program, as well as to allow further development of the curriculum and increase the emphasis on clinical translation of biomechanics and regenerative medicine research. ###

NIH Funds Pitt Study to Develop Culture-Free Fat Cell-Based Vascular Grafts in Cardiovascular Disease Patients

Bioengineering

PITTSBURGH (April 28, 2016) … The National Institutes of Health have awarded David Vorp, the William Kepler Whiteford Professor of Bioengineering and Associate Dean for Research of the Swanson School of Engineering at Pitt, with a two-year, $417,838 R21 grant for research into the use of cells from a patient’s own adipose (fat)  as vascular grafts in arterial bypass surgery. This new method, which has been successful in rat subjects, would allow surgeons to perform bypass surgeries without harvesting arteries or veins from the patient or requiring the time to isolate and grow a specific cell type, such as a stem cell. Coronary bypass procedures often use other arteries or veins as a source for grafts. Arteries that can be used safely as a bypass graft in a different location are in short supply. The great saphenous vein in the leg is one of the most common sources for arterial grafts, but re-purposing veins as arterial bypass grafts can cause complications. “The vein graft, even though it is the most widely used graft material for the coronary or other small diameter artery applications, is not ideal,” said Vorp. “The problem is that veins are not arteries; they are built differently because they have different purposes in the body. Arteries pulse, and they are under higher pressure than veins. When you take a vein segment and put it under arterial conditions, it responds by thickening, which can cause the same blockage you were trying to treat.” Vorp’s study, “An Autologous, Culture-free Adipose Cell-based Tissue Engineered Vascular Graft,” will explore ways to facilitate the translation of technology that has been under development by Dr. Vorp and his associates for a number of years. The current methodology requires stem cells to be carefully extracted from the fat and then spend time in culture before constructing a graft, which itself spends time in additional culture. This new research will explore the potential for skipping the culture steps entirely, first by using all of the fat cells from the patient (instead of isolating and expanding the stem cells alone) and then by implanting the graft immediately instead of culturing it first. The Pitt researchers will also design a way to “scale-up” the process that creates their engineered graft. The method used for small-scale grafts in rats won’t work when the construct is enlarged to a human-scale. “The key focus of the study is the translational aspects,” said Vorp. “We have shown that we can regenerate a small-diameter aorta in a rat that functions for up to a year. We now need to determine how to overcome some logistical issues so that we can use this technology to help human patients, which is why we started the research in the first place. This R21 grant is really facilitating the start of that process.” R21 research grants are designated for exploratory/developmental research, generally still in the conceptual stage. They are often awarded to high risk and high reward studies that have the potential to become much larger in scope. J. Peter Rubin, University of Pittsburgh Medical Center Endowed Professor, Chair of Plastic Surgery and Professor of Bioengineering, as well as William R. Wagner, director of Pitt’s McGowan Institute for Regenerative Medicine and Professor of Surgery, Bioengineering and Chemical Engineering, will collaborate with Vorp on the study. “This grant is another manifestation of the great environment here at Pitt where you have no walls between engineering, science and clinical medicine. Research is really well integrated, and partnerships are encouraged,” said Vorp. ###
