Transcriptome analysis of lung epithelial cells and lung fibroblasts from various developmental stages (E18.5, P0.5, P2, P7, P28, and P56). Transcriptome analysis of lung epithelial cells and lung fibroblasts from various developmental stages (E18.5, P0.5, P2, P7, P28, and P56)

In the alveoli, lung fibroblasts are in close contact with alveolar epithelial cells type 2, and are considered to support alveolar epithelial cells, forming an alveolar stem cell niche. However, what fibroblast-to-epithelial cell interactions occur during the alveolar maturation stage remains unclear. To understand the lung fibroblast-to-epithelial cell interactions, we performed time-course 3´SAGE-seq analysis of lung epithelial cells and fibroblasts. Overall design: Lung epithelial cells and lung fibroblasts from various developmental stages (E18.5, P0.5, P2, P7, P28, and P56) were purified by cell sorting. The time series transcriptome of the epithelial cells and fibroblasts was generated by 3'SAGE-seq using Ion Proton sequencer.
