Abstract
Bronchopulmonary dysplasia (BPD) is the most common chronic respiratory disease in
premature infants and affects their survival rate and quality of life. There are no
reliable interventions for the prevention or treatment of BPD, but the emergence of
mesenchymal stem cell (MSC) therapies has brought new hope. Research has shown that
paracrine may be the therapeutic mechanism of action underlying physiological improvements
in the lungs of BPD patients treated with MSC therapy. The therapeutic vector in the
MSC secretome comprises exosomes with low immunogenicity and stability, and that can
easily cross the blood-brain barrier. In the future, exosomes may become the preferred
treatment for BPD in clinical settings. Here, we review the progress of preclinical
research on the use of MSC-derived exosomes as a promising treatment option for BPD.
Key Points
-
There is a lack of effective treatment for BPD.
-
MSCs' therapeutic effect is exerted through paracrine.
-
MSC-derived exosomes (MSC-Exos) possess similar biological functions to MSCs.
-
MSC-Exos can repair lung injury in BPD animal models.
