Monocytes were isolated using CD14+ magnetic bead selection (98%–99% purity) from three well-characterized IPF patients (with definite UIP pattern fibrosis on CT scan) who were not on anti-fibrotics, and were non-smokers (all male; aged 57, 76, and 78y) and three healthy controls (HC) (non-smokers, no medications; aged 65, 68, and 71y; all male). The gene discussed is CD14; the disease is idiopathic pulmonary fibrosis.
