This study is an open-label, single-center, dose escalation study to evaluate of safety and efficacy of human umbilical cord -derived mesenchymal stem cells (hUC-MSCs) in premature infants at high risk for Bronchopulmonary DysplasiaBPD


BPD is a chronic lung disease that occur in premature infants receiving prolonged oxygen pulmonary and ventilator therapy. It remains a main complication of extreme prematurity and currently lacks efficient treatment.The mortality rate of one year after birth is still high and the quality of life is not optimistic.

hUC-MSCs are widely used in clinic due to their low immunogenicity and convenient to get. Many animal study had shown that hUC-MSCs had therapeutic effects on a variety of animal models of lung disease.Furthermore,there are a large number of clinical trials of MSCs applied to various system diseases and the safety was verified.So, the main purpose of this study is to evaluate the safety and efficacy of hUC-MSCs in participants at high risk for BPD

Condition Bronchopulmonary Dysplasia, bronchopulmonary dysplasia (bpd)
Treatment transplantation of hUC-MSCs, No transplantation of hUC-MSCs
Clinical Study IdentifierNCT03774537
