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: Production of an AIDS vaccine in algae

Today, plants and microorganisms are heavily used for the production of medicinal products. The production of biopharmaceuticals in plants, also referred to as “Molecular Pharming”, represents a continuously growing field of plant biotechnology. Preferred host organisms include yeast and crop plants, such as maize and potato – plants with high demands. With the help of a special algal strain, the research team of Prof. Ralph Bock at the Max Planck Institute of Molecular Plant Physiology in Potsdam strives to develop a more efficient and resource-saving system for the production of medicines and vaccines. They tested its practicality by synthesizing a component of a potential AIDS vaccine.

The use of plants and microorganisms to produce pharmaceuticals is nothing new. In 1982, bacteria were genetically modified to produce human insulin, a drug...

Im Focus: The most accurate optical single-ion clock worldwide

Atomic clock experts from the Physikalisch-Technische Bundesanstalt (PTB) are the first research group in the world to have built an optical single-ion clock which attains an accuracy which had only been predicted theoretically so far. Their optical ytterbium clock achieved a relative systematic measurement uncertainty of 3 E-18. The results have been published in the current issue of the scientific journal "Physical Review Letters".

Im Focus: Goodbye ground control: autonomous nanosatellites

The University of Würzburg has two new space projects in the pipeline which are concerned with the observation of planets and autonomous fault correction aboard satellites. The German Federal Ministry of Economic Affairs and Energy funds the projects with around 1.6 million euros.

Im Focus: Flow phenomena on solid surfaces: Physicists highlight key role played by boundary layer velocity

Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between the liquid and the surface that induces the liquid to slip. This results in an increase in the average flow velocity of the liquid and its throughput. This was demonstrated by studying the behaviour of droplets on surfaces with different coatings as they evolved into the equilibrium state. The results could prove useful in optimizing industrial processes, such as the extrusion of plastics.

The study has been published in the respected academic journal PNAS (Proceedings of the National Academy of Sciences of the United States of America).
