Stem cells to treat lung disease in preterm infants

06.02.2014
Advances in neonatal care for very preterm infants have greatly increased the chances of survival for these fragile infants.

However, preterm infants have an increased risk of developing bronchopulmonary dysplasia (BPD), a serious lung disease, which is a major cause of death and lifelong complications.

In a new study scheduled for publication in The Journal of Pediatrics, researchers evaluated the safety and feasibility of using stem cell therapies on very preterm infants to prevent or treat BPD.

Won Soon Park, MD, PhD, and colleagues from Samsung Medical Center and Biomedical Research Institute, Seoul, Republic of Korea, conducted a phase I, single-center trial of intratracheal transplantation of human umbilical cord blood-derived mesenchymal stem cells to nine very preterm infants (24-26 weeks gestational age) who were at high risk of developing BPD.

All patients who received the treatment tolerated the procedure well without any immediate serious adverse effects. Thirty-three percent of treated infants developed moderate BPD and none developed severe BPD, and 72 percent of a matched comparison group developed moderate or severe BPD.

Another serious side effect of very preterm birth, retinopathy of prematurity requiring surgery, tended to occur less often in treated infants. Overall, all nine treated infants survived to discharge, and only three developed moderate BPD.

This phase I study suggests that intratracheal administration of mesenchymal stem cells is safe and feasible. According to Dr. Park, "These findings strongly suggest that phase II clinical trials are warranted to test the efficacy of mesencymal stem cell transplantation, which could lead to new therapies to prevent or cure BPD." Dr. Park and colleagues are currently conducting a long-term safety and follow-up study of these nine preterm infants (ClinicalTrials.gov: NCT01632475).

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
