Declining life expectancy and increasing all-cause mortality in the United States have been associated with unhealthy behaviors, socioecological factors, and preventable disease. A growing body of basic science, clinical research, and population health evidence points to the benefits of healthy behaviors, environments, and policies to maintain health and prevent, treat, and reverse the root causes of common chronic diseases. Similarly, innovations in research methodologies, standards of evidence, emergence of unique study cohorts, and breakthroughs in data analytics and modeling create new possibilities for producing biomedical knowledge and clinical translation. To understand these advances and inform future directions research, The Lifestyle Medicine Research Summit was convened at the University of Pittsburgh on December 4–5, 2019. Read More

A decade ago, McGowan Institute for Regenerative Medicine faculty member Eric Lagasse, PharmD, PhD, Associate Professor in the Department of Pathology, University of Pittsburgh with a secondary appointment in Pitt’s Clinical and Translational Institute, the Director of the Cancer Stem Cell Center at the McGowan Institute, and a world leader in ectopic transplantation research, began a series of experiments that would form the foundation for LyGenesis. He discovered that hepatocytes (liver cells) transplanted into lymph nodes would not just survive, but thrive, organize, and begin to function as miniature ectopic livers, exerting life-saving effects in otherwise fatal small and large animal models of end stage liver disease. His research, published in Nature Biotechnology, Current Opinions in Organ Transplantation, and Organogenesis, confirms that it is possible to harness the body’s lymph nodes as bioreactors for growing functional ectopic organs.

Researchers from Sechenov University and the University of Pittsburgh compared the properties of two groups of extracellular vesicles. Either present in a liquid phase or attached to the fibers of the extracellular matrix, these vesicles facilitate metabolism and cell-cell communication. A better understanding of their structure, production and movement can help create new bioengineered materials and repair damaged tissues more quickly. Read More

Brain tissue lost after a stroke is not regenerated, although a repair response associated with neurogenesis does occur. A failure to regenerate functional brain tissue is not caused by the lack of available neural cells, but rather the absence of structural support to permit a repopulation of the lesion cavity. Inductive bioscaffolds can provide this support and promote the invasion of host cells into the tissue void.¹ Read More

As the Baby Boomer generation gets older, the number of Americans over 65 continues to grow.

Starfish can repair injured arms and reptiles can regrow severed tails; from bacteria to humans, every species is capable of regeneration, albeit to variable extents. These functions help make species more resilient, but how can we apply the knowledge of these regenerative mechanisms to improve human health? The University of Pittsburgh Department of Bioengineering has been collaboratively working to address this question through research efforts in tissue engineering and regenerative medicine.

The utilization of mammalian extracellular matrix (ECM), or its derivatives, as an inductive template for constructive remodeling of tissue is a common theme of most research activities. Read More

Lizards can regrow an entire tail and salamanders can regrow a leg. Unfortunately, our human bodies mainly just close wounds and make scar tissue. But just imagine the possibilities if we could grow a new limb after an amputation or a new organ, rather than needing a transplant?  That is the focus of a recent interview by Julie Rose, BYU Radio, with McGowan Institute for Regenerative Medicine deputy director Stephen Badylak, DVM, PhD, MD, professor in the Department of Surgery and director of the Center for Pre-Clinical Tissue Engineering within the McGowan Institute.

Extracellular matrix (ECM) hydrogel promotes tissue regeneration in many peripheral soft tissues. However, the brain has generally been considered to lack the potential for tissue regeneration.  In their study published in Acta Biomaterialia, McGowan Institute for Regenerative Medicine affiliated faculty member Michel Modo, PhD, Professor in the Department of Radiology at the University of Pittsburgh with secondary appointments in the Department of Bioengineering and the Center for Neural Basis of Cognition, and McGowan Institute Deputy Director Stephen Badylak, DVM, PhD, MD, Professor in the Department of Surgery at the University of Pittsburgh and Director of the Center for Pre-Clinical Tissue Engineering within the Institute, demonstrated that tissue regeneration in the brain can be achieved using implantation of ECM hydrogel into a tissue cavity. They and the research team further demonstrated that a structure-function relationship is key to promote tissue regeneration in the brain.  This approach offers new avenues for the future treatment of chronic tissue damage caused by stroke and other acute brain injuries.

Platelet-rich plasma (PRP) is believed to provide pain relief and help improve joint function in degenerative joint disease, but a new study—coauthored by McGowan Institute for Regenerative Medicine affiliated faculty member Rocky Tuan, PhD, Vice-Chancellor and President of The Chinese University of Hong Kong—has shown that it does not act by promoting stem cell proliferation or enhance the cartilage formation capabilities of mesenchymal stem cells (MSCs). The effects of PRP treatment on cartilage formation and chondrogenesis in the presence of adult human MSCs derived from two different sources are reported in the study published in Tissue Engineering, Part A, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Per the United Network for Organ Sharing, every ten minutes, someone is added to the national transplant waiting list in need of a kidney, liver, pancreas, heart, lung, or intestine, the most needed organs of 2017.  As of the end of January 2018, there were 114,883 people needing a lifesaving organ transplant (total waiting list candidates) with 74,722 of those people being active waiting list candidates.  Tragically, on average, 20 people die each day while waiting for a transplant.  More than 7,000 candidates died in 2016 while on the wait list, or within 30 days of leaving the list for personal or medical reasons, without receiving an organ transplant.

When a patient with heart disease is in need of a vascular graft but doesn’t have any viable veins or arteries in his or her own body, surgeons can rely on synthetic, tissue-engineering grafts. However, the body often treats these substitutes as a threat and rejects them. Researchers at the University of Pittsburgh are developing synthetic grafts that mimic the body’s own blood vessels to mitigate many of the complications of bypass surgery. Read More
