Circulating Fibrocytes Correlate With Bronchiolitis Obliterans Syndrome Development After Lung Transplantation: A Novel Clinical Biomarker

Increased circulating fibrocyte levels correlate with the development of BOS after lung transplantation and positively correlate with advancing BOS stage. Quantification of circulating fibrocytes could serve as a novel biomarker and possible therapeutic target for BOS development in lung transplant patients.
