Description
Macrophages (MF) have been shown to contribute to fibrogenesis, however the underlying mechanisms and specific MF subsets involved remain unclear. Lung MF can be divided into two subsets: Siglec-Fhi resident alveolar MF and CD11bhi MF that primarily arise from immigrating monocytes. RNA-seq analysis was performed to compare these MF subsets during fibrosis. CD11bhi MF, not Siglec-Fhi MF, expressed high levels of pro-fibrotic chemokines and growth factors. Overall design: C56BL/6 WT mice were treated intratracheally with bleomycin. 8 days later, CD64+Mertk+ MF were sorted into Siglec-F(high) and CD11b(high) subsets. SiglecF(high) MF from naïve mice were also sorted. RNA was isolated and RNA-seq was performed to compare MF subsets.
