Disruption of developmental processes affecting the fetal lung leads to pulmonary hypoplasia. Pulmonary hypoplasia results from several conditions including congenital diaphragmatic hernia (CDH) and oligohydramnios. Both entities have high morbidity mortality, no effective therapy that fully restores normal development. Hypoplastic lungs impaired growth (arrested branching morphogenesis), maturation (decreased epithelial/mesenchymal differentiation), vascularization (endothelial dysfunction vascular remodeling leading postnatal hypertension). Herein, we discuss pathogenesis role microRNAs (miRNAs) during pathological Since multiple cells pathways are altered, ideal strategy for hypoplastic is deliver a addresses all aspects abnormal In this review, report on novel regenerative approach based administration extracellular vesicles derived amniotic fluid stem (AFSC-EVs). Specifically, describe effects AFSC-EVs in rodent human models hypoplasia, their mechanism action via release cargo, miRNAs, anti-inflammatory properties. We also compare cargo contents EVs AFSCs mesenchymal stromal (MSCs). Overall, there compelling evidence antenatal rescues features development experimental Lastly, steps need be taken translate promising EV-based bench bedside. These include strategies overcome barriers commonly associated with EV therapeutics specific challenges related cell-based therapies medicine.

Antenatal administration of extracellular vesicles from amniotic fluid stem cells (AFSC-EVs) reverses features pulmonary hypoplasia in models congenital diaphragmatic hernia (CDH). However, it remains unknown which lung cellular compartments and biological pathways are affected by AFSC-EV therapy. Herein, we conducted single-nucleus RNA sequencing (snRNA-seq) on rat fetal CDH lungs treated with vehicle or AFSC-EVs. We identified that intra-amniotically injected AFSC-EVs reach the rats CDH, where they promote branching morphogenesis epithelial cell differentiation. Moreover, snRNA-seq revealed have a multilineage inflammatory signature macrophage enrichment, is reversed treatment. Macrophage enrichment was confirmed immunofluorescence, flow cytometry, inhibition studies GW2580. validated human autopsy samples. Together, this study advances knowledge pathogenesis further evidence value an EV-based therapy for fetuses.

Abstract Oligohydramnios (decreased amniotic fluid volume for gestational age) is a severe condition associated with high morbidity and mortality mainly due to fetal pulmonary hypoplasia. Currently, there are limited treatment options promote lung development. Administration of stem cells their derivates have shown promising regenerative properties several neonatal diseases related arrested Herein, we first characterized hypoplasia secondary oligohydramnios in surgical rat model. Experimental induction led impaired growth, branching morphogenesis (fewer airspaces decreased Fgf10 , Nrp1 Ctnnb1 expression), proximal/distal progenitor cell patterning Sox2 Sox9 TGF-β signaling. We then tested antenatal administration extracellular vesicles derived from (AFSC- EVs). In lungs, AFSC-EV improved airway at least part through the release miR-93-5p. Our experiments suggest that miR-93-5p blocked SMAD 7, resulting upregulation pSMAD2/3 restoration Conversely, lungs treated antagomir 93-5p transfected AFSC- EVs had This study reporting derivatives could be potential therapy rescue development fetuses oligohydramnios. Highlights Pulmonary rats by improves patterning. effects mediated via modulation signaling AFSC-EVs.
