Abstract
RATIONALE: The chronic lung disease bronchopulmonary dysplasia (BPD) is the most severe complication of extreme prematurity. BPD results in impaired lung alveolar and vascular development and long-term respiratory morbidity, for which only supportive therapies exist. Umbilical cord-derived mesenchymal stromal cells (UC-MSCs) improve lung structure and function in experimental BPD. Results of clinical trials with MSCs for many disorders do not yet match the promising preclinical studies. A lack of specific criteria to define functionally distinct MSCs persists.
OBJECTIVES: To determine and correlate single-cell UC-MSC transcriptomic profile with therapeutic potential.
METHODS: UC-MSCs from five term donors and human neonatal dermal fibroblasts (HNDFs, control cells of mesenchymal origin) transcriptomes were investigated by single-cell RNA sequencing analysis (scRNA-seq). The lung-protective effect of UC-MSCs with a distinct transcriptome and control HNDFs was tested in vivo in hyperoxia-induced neonatal lung injury in rats.
MEASUREMENTS AND MAIN RESULTS: UC-MSCs showed limited transcriptomic heterogeneity, but were different from HNDFs. Gene ontology enrichment analysis revealed distinct - progenitor-like and fibroblast-like - UC-MSC subpopulations. Only the treatment with progenitor-like UC-MSCs improved lung function and structure and attenuated pulmonary hypertension in hyperoxia-exposed rat pups. Moreover, scRNA-seq identified major histocompatibility complex class I as a molecular marker of non-therapeutic cells and associated with decreased lung retention.
CONCLUSIONS: UC-MSCs with a progenitor-like transcriptome, but not with a fibroblast-like transcriptome, provide lung protection in experimental BPD. High expression of major histocompatibility complex class I is associated with reduced therapeutic benefit. scRNA-seq may be useful to identify subsets of MSCs with superior repair capacity for clinical application.
