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.

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.

The First Demonstration of a Tissue Forming Through an Endogenous Process in the Brain

By The McGowan Institute For Regenerative Medicine | News Archive, Tissue Engineering | September 19, 2018

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 Does Not Promote Stem Cell-Mediated Cartilage Repair

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.

Vascular Bypass Grafting: A Biomimetic Engineering Approach

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.

Regenerative Medicine for Whole Organ Replacement

By The McGowan Institute For Regenerative Medicine | News Archive, Tissue Engineering | March 1, 2017

Extracellular matrix (ECM) represents the structural and functional molecules secreted by the resident cells of every tissue in the body. Researchers in the laboratory of Stephen Badylak, DVM, PhD, MD, Professor in the University of Pittsburgh’s Department of Surgery, a deputy director of the McGowan Institute for Regenerative Medicine, and Director of the Center for Pre-Clinical Tissue Engineering within the Institute, have extensive experience isolating and harvesting this ECM and producing usable formats for use in pre-clinical animal and bench top studies. Scientists routinely produce ECM from tissue such as small intestine, urinary bladder, and liver tissue. The cells of these tissues are removed by physical, enzymatic, and/or chemical methods so that only the native ECM remains.

Innovative Surgical Practices Using Tissue-Based Regenerative Therapies May Be More Tightly Regulated

By The McGowan Institute For Regenerative Medicine | News Archive, Tissue Engineering | June 9, 2016

The therapeutic use of human cell and tissue products is highly regulated by the U.S. government, but a specific exception allows surgeons to harvest, manipulate, and implant tissues in many commonly performed surgical procedures. While the operating room is often the stage where innovations in tissue engineering and regenerative medicine are realized, as surgeons use grafted tissues, novel biomaterials, and new approaches to numerous procedures including performing breast, chest and abdominal wall, and pelvic floor reconstruction, new FDA draft guidelines would place even tighter restrictions on surgical practice and may limit the development of new therapies. This topic is examined in an Editorial in Tissue Engineering, Part A, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.  The article is available free for download on the Tissue Engineering website until July 1, 2016.  McGowan Institute for Regenerative Medicine faculty member J.

Pitt Spinout Company Wins 2015 Innovator of the Year—Life Sciences Tech 50 Award

Cohera Medical, Inc., a company spun out of the University of Pittsburgh in 2006, was named by the Pittsburgh Technology Council as the 2015 Innovator of the Year—Life Sciences during its annual Tech 50 Awards ceremony, which was held October 29 at the Wyndham Grand Pittsburgh, Downtown.  McGowan Institute for Regenerative Medicine affiliated faculty member Eric Beckman, PhD, and oral and maxillofacial surgeon Michael Buckley (formerly of Pitt’s School of Dental Medicine) developed the core technology that led to the company’s first adhesive technology product offering—TissuGlu.  TissuGlu is a biodegradable, biocompatible product that provides surgeons with an alternative to stapling, stitching, or less-effective surgical wound sealants currently used to close large tissue flaps resulting from abdominoplasties (tummy tucks) and other surgical procedures.

“The original collaboration between Michael and myself was targeted at an entirely different technology and clinical issue, where we essentially stumbled upon the potential to create a biocompatible adhesive,” said Dr. Beckman, the George M. Bevier Professor of Engineering in Pitt’s Swanson School of Engineering. “Clinicians have lacked internal adhesives that are both strong and safe, and it’s exciting that TissuGlu was the first internal tissue adhesive to be approved by the FDA.”

Lab-Grown 3-D Intestine Regenerates Gut Lining in Pre-Clinical Trial

By The McGowan Institute For Regenerative Medicine | News Archive, Tissue Engineering | October 22, 2015
Untitled-1
Working with gut stem cells from humans and mice, scientists from the Johns Hopkins Children’s Center and the University of Pittsburgh have successfully grown healthy intestine atop a 3-D scaffold made of a substance used in surgical sutures. In a further step that takes their work well beyond proof of concept, McGowan Institute for Regenerative Medicine deputy director Stephen Badylak, D.V.M, Ph.D., M.D., Pitt graduate students Jenna Dziki and Timothy Keane, and researchers report their laboratory-created intestine successfully regenerated gut tissue in the colons of pre-clinical animals with missing gut lining.

The experiments, described ahead of print in the journal Regenerative Medicine, bring researchers closer to creating an implantable intestine as replacement therapy for a range of devastating disorders – including infections, cancer, and trauma – that result in loss or death of gut tissue. Chief among them is a condition that affects 12 percent of premature newborns, called necrotizing enterocolitis (NEC), which is marked by the rapid death of intestinal cells and permanent loss of intestinal tissue.
