Juan Sanchez-Esteban, MD, an associate professor of pediatrics at The Warren Alpert Medical School of Brown University and staff neonatologist at Women & Infants Hospital of Rhode Island, was awarded a $25,000 grant in support of his project titled “Role of Exosomes in Fetal Lung Development.” This is a pilot project funded by Center of Biomedical Research Excellence (COBRE) to investigate the role of exosomes in fetal lung development. Exosomes are small particles released by the cells containing important information for cell-to-cell communication such as genetic material and proteins.

“This pilot study will investigate whether isolated lung cells exposed in the lab to stretch, mimic the stretch that normally occurs in lung development releasing exosomes. We will also test whether these isolated exosomes given to the cells stimulate development,” said Dr. Sanchez-Esteban. “The fetal lung requires distention for normal development which is generated by fluids released inside the lungs that generate this stretch or distention. If you suppress any physical forces required for fetal lung development, the lungs do not form properly.”

The results of these investigations regarding the administration of exosomes to fetus or preterm newborns could be the next step in accelerating lung development in high-risk cases, explained Dr. Sanchez-Esteban.

Dr. Sanchez-Esteban received his medical degree from the Universidad Autonoma De Barcelona in Spain. He went on to complete his internship at the Metropolitan Hospital Center and his residency at the Metropolitan Health Medical Center in New York. His fellowship was completed with Women & Infants Hospital. Dr. Sanchez-Esteban also holds privileges at Kent Hospital and Memorial Hospital, both members of Care New England.
