Project description:We report the single cell RNA sequencing of the lung epithelium of mice expressing the SP-C BROCHOS mutation (SP-C C121G) at 3 and 7 days after tamoxifen induced mutation expression. The control sample for this experiment are mice hypomorphic for the SP-C mutation (SP-C C121Gneo). This study allow for the identification of unique lung epithelial cell states that emerge following SP-C mutation expression
Project description:The goal of this study was to compare wild-type adult homeostatic lung epithelium to Hopx-creERT2-induced Yap/Taz KO in adult AT1 cells. Three adult mice with identical genotypes and either sex were pooled after fluorescence-activated cell sorting and loaded into the 10X Chromium scRNA sequencing library generation pipeline.
Project description:To comprehensively study the heterogeneity within distal airway epithelium, we performed single cell transcriptomic analysis of the naive lung samples. Our analysis reveals that distal lung airway epithelial cells are highly heterogenous. We employed supervised clustering to identify a rare group of cells with transcriptional similiarities to embryonic distal lung bud tip progenitors. This approach identified a quiescent progenitor population of airway cells that accounted for all in vitro regenerative activity. Furthermore, these cells were also required for in vivo transplantation, reconstitution of alveoli, and functional recovery of injured mice. These findings indicate that small subpopulations of specialized stem/progenitors are required for effective lung regeneration and could potentially be used as therapeutic adjuncts after major lung injury.
