Tue, Oct 16 6:00am · Regenerative medicine facilities and expertise in Florida

The Regenerative Medicine Therapeutic Suites has seen 1,000 patients since opening on Mayo Clinic’s Florida campus almost two years ago. The model, which integrated patient care with laboratory functions, is enabling the development and use of regenerative medicine products.

The unique space serves both patients and clinicians, providing a place for multidisciplinary teams to expand current projects in order to deliver individualized regenerative therapies and procedures to patients.

The Regenerative Medicine Therapeutic Suites have prompted — and been used in — several research projects in the areas of orthopedics, dermatology, reconstructive surgery and gastroenterology. From the treatment of pressure wounds to stroke to Alzheimer’s disease and beyond, the suites ensure a seamless pathway to translate emerging regenerative treatments to patient care.

In the video below, Shane Shapiro, M.D., program director for the Regenerative Medicine Therapeutic Suites and assistant professor of orthopedic surgery discusses the results of his randomized controlled trial of bone marrow aspiration and concentration for knee osteoarthritis.

Tue, Oct 9 6:00am · Diabetes 3, 2, 1

Often people with diabetes have brain changes that are hallmarks of both Alzheimer’s disease and vascular dementia. Some researchers believe that each condition fuels the damage caused by the other. That link may occur as a result of the ways that type 2 diabetes affects the ability of the brain and other body tissues to use sugar (glucose) and respond to insulin.

“To function well, the neurons in your brain need fuel. If you don’t have a good blood supply to the brain, then you don’t get enough glucose,” says Guojun Bu, Ph.D., Mayo Clinic neuroscientist and associate director of the Center for Regenerative Medicine at Mayo Clinic in Jacksonville, Florida.

The reduction of blood flow to the brain caused by damaged blood vessels may be why those with diabetes have a higher risk of Alzheimer’s disease. Diabetes and Alzheimer’s disease are connected in ways that aren’t yet fully understood. Dr. Bu and other researchers are studying how insulin resistance may affect the brain and result in Alzheimer’s disease or other types of dementia.

The connection between diabetes and Alzheimer’s was recently discussed in the Everyday Health article, Why Some Researchers Are Calling Alzheimer’s Disease a ‘Type 3 Diabetes’. “It’s really more of a research term, rather than a medical term,” explains Dr. Bu. About 20 percent of the human population carries the riskier form of the gene APOE, called the E4. It is anticipated that more than 50 percent of Alzheimer’s cases can be linked to APOE4, according to the study, which was published in Neuron.

Regenerative Endocrinology Research at Mayo Clinic

The endocrine cells of the pancreas are responsible for maintaining blood glucose levels. Glucose-responsive, insulin-secreting cells in the islets (beta cells) are dysfunctional in both type 1 and type 2 diabetes. In type 1 diabetes, beta cells are destroyed, while in type 2 diabetes, they may not produce enough insulin.

The Islet Regeneration Program at Mayo Clinic is poised to develop novel therapies for diabetes. The islet regeneration researchers are taking multiple approaches to restore, protect and replace pancreatic islets.

Mayo Clinic researchers are also investigating gene therapy as a potential means of enhancing the body’s natural ability to regenerate beta cells.

Tue, Aug 28 6:00am · Stem cell differentiation for diabetes: Alexander Revzin, Ph.D.

Alexander Revzin, Ph.D., is a professor of biomedical engineering at Mayo Clinic and recipient of a 2018 Regenerative Medicine Minnesota Research Award. He is developing microcapsules that could be used as cell carriers during differentiation of stem cells into pancreatic islets. These same capsules may also be useful as vehicles for islet transplantation. This technology will enable better scale-up of islet production from stem cells, may result in cost reduction, and may also alleviate problems associated with immune rejection of transplanted islets.

Thu, Aug 16 6:00am · Investigating gene therapy strategies for obesity: Ping Chen, Ph.D.

The major challenge in treating obesity is not just losing weight, but preventing weight from coming back. With a research grant form Regenerative Medicine Minnesota, Ping (Vicky) Chen, Ph.D., Mayo Clinic research associate,  is studying a new treatment strategy using gene transfer therapy to safely target brain mechanisms that control hunger and energy output.

Dr. Chen’s previous research in mice found that gene transfer of a well-tolerated liver enzyme could revolutionize clinical treatment of obesity, making it easier for obese patients to lose weight safely and minimize later weight gain. Her research on the mechanism behind weight control will further determine if this approach might succeed in humans. Researchers expect the effects to correlate positively with reduction in ailments such as diabetes, metabolic syndrome and fatty liver disease.

Mon, Aug 6 6:00am · Regenerative medicine in novel fetal therapy program

A life-saving procedure improves fetal lung health and reduces post-natal complications

Specialists at Mayo Clinic are pioneering a life-saving procedure as part of a clinical trial for babies with congenital diaphragmatic hernia (CDH).

When a baby’s lungs are not adequately developed at birth, severe complications and even death can result. Waiting for the baby to be born to intervene may be too late. A new study is underway to document fetal lung growth from early intervention before birth.

CDH develops when a baby’s chest cavity is compressed and lung development is restricted because the diaphragm does not close completely and the abdominal organs push into the chest cavity. CDH is a life-threatening condition affecting 1 in 2,500 births.

The fetal endoscopic tracheal occlusion (FETO) procedure inserts an ultrasound-guided fetal endoscope through the mother’s abdomen or uterus into the amniotic cavity. The tiny scope advances to the fetal mouth and trachea, and a balloon is placed and inflated to close the trachea to promote lung growth.  The balloon is removed in a similar procedure a few weeks later and before delivery. The minimally invasive procedure is documented in the June issue of Mayo Clinic Proceedings. The study includes two cases of severe CDH and documents fetal lung growth and reversal of severe pulmonary hypoplasia.




One of those case studies is Xavier Sorying, now a healthy 7-month old baby. Before Xavier was born, his diaphragm — the muscle that separates the abdomen from the chest — developed a hole, resulting in CDH.

A team of physicians, including Rodrigo Ruano, M.D., Ph.D., fetal surgeon, and Denise Klinkner, M.D., pediatric surgeon, performed a FETO. The resulting pressure then expanded Xavier’s lungs and encouraged the growth of essential structures related to his lung function.

“The fact that we collaborated and had such a great outcome points to what Mayo Clinic strives to do, which is to put the patient first,” says Dr. Klinkner.

You can read Xavier’s full story on Sharing Mayo Clinic.

The study was funded by a grant from Regenerative Medicine Minnesota from the State of Minnesota. Dr. Ruano is the director of Mayo Clinic’s Fetal Diagnostic and Intervention Center and the division chair of Maternal and Fetal Medicine at Mayo Clinic.

Tue, Jul 17 6:00am · Researching gene therapy for liver diseases: Joseph Lillegard, M.D., Ph.D.

Joseph Lillegard, M.D., Ph.D., is a Regenerative Medicine Minnesota research grant recipient. He is researching gene therapy to fight inborn errors of metabolism of the liver, primarily Hereditary Tyrosinemia Type 1 (HT1), a metabolic disorder caused by an enzyme deficiency. HT1 is a genetic disorder that can lead to liver and kidney failure, and is fatal without treatment. There is no cure. This project aims to develop a lentivirus-mediated gene therapy to treat multiple inborn errors of liver metabolism, with the research in HT1 serving as a model for future studies of other rare liver diseases.

Dr. Lillegard is a supplemental consultant at Mayo Clinic and a pediatric general and thoracic surgeon at Children’s Minnesota.
