UTHealth Pediatric Surgery Expands Regenerative Medicine Program

Newswise About 3 percent of the babies born in the United States have a birth defect. Children without a birth defect are also susceptible to injury or disease. At The University of Texas Health Science Center at Houston (UTHealth), regenerative medicine researchers are exploring innovative ways to treat these conditions.

The Department of Pediatric Surgery at the UTHealth Medical School operates a research program devoted to childhood conditions that is seeking to harness the bodys regenerative powers to repair malformed organs and to mitigate injury from illness or trauma. It is called the Childrens Regenerative Medicine Program.

Kevin Lally, M.D., chairman of the Department of Pediatric Surgery at the UTHealth Medical School and surgeon-in-chief at Children's Memorial Hermann Hospital, announced the recruitment of four stem cell scientists to the program. The researchers are associate professor Yong Li, M.D., Ph.D., and assistant professors Scott Olson, Ph.D., Fabio Triolo, M.Phil., D.d.R., Ph.D., and Pamela Wenzel, Ph.D.

We were able to recruit outstanding investigators thanks in part to the generous support of Mrs. Clare Glassell and Mrs. Evelyn Griffin, said Lally, who is the A.G. McNeese Chair in Pediatric Surgery and the Richard Andrassy, M.D., Endowed Distinguished Professor at UTHealth. Our program in regenerative medicine is committed to a collaborative environment in which clinicians work with basic researchers.

Lally has a special interest in the treatment of a potentially life-threatening condition known as congenital diaphragmatic hernia that occurs in as many as one in every 2,500 live births and is often treated surgically. The diaphragm is a muscle separating the chest cavity and belly and is important for breathing.

The core fundamental problem is infants born with structural problems that need to be repaired, said Lally, who believes doctors may be able to use stem cells to replace the diaphragm or repair defects in the abdominal wall.

Stem cells may also help children with traumatic brain injuries. Charles Cox Jr., M.D., professor of pediatric surgery, director of the Pediatric Trauma Program at the UTHealth Medical School/Childrens Memorial Hermann Hospital and The Childrens Fund Inc. Distinguished Professor in Pediatric Surgery, is leading clinical research on the use of these versatile cells to address this leading cause of death and lifelong disability among children.

Yong Li, M.D., Ph.D.

Li previously served as a tenure track assistant professor in the Stem Cell Research Center at Childrens Hospital of Pittsburgh, where his laboratory studied the regenerative power of newts and salamanders in the hope of applying this information to the care of people.

Newts are able to regenerate missing body parts including limbs, spine and heart. Li has studied growth factors that facilitate this regeneration process in some amphibians and how they could be used for stem cell population and tissue engineering.
