Human Mesenchymal Stem Cells For Infants At High Risk For Bronchopulmonary Dysplasia

March 5, 2019 updated by: Xia Yunqiu, Children's Hospital of Chongqing Medical University

Intravenous Human Umbilical-Cord-Derived Mesenchymal Stem Cells For Premature Infants Ａt High Risk For Bronchopulmonary

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 Dysplasia（BPD）

Detailed Description

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
