(Submitter supplied) Tissue regeneration is a multi-step process mediated by diverse cellular hierarchies and states that are also implicated in tissue dysfunction and pathogenesis. Here, we leveraged single-cell RNA sequencing in combination with in vivo lineage tracing and organoid models to finely map the trajectories of alveolar lineage cells during injury repair and lung regeneration. We identified a distinct AT2-lineage population, Damage-Associated Transient Progenitors (DATPs), that arises during alveolar regeneration. more...

(Submitter supplied) Alveolar epithelial cell fate decisions drive lung development and regeneration. Using transcriptomic and epigenetic profiling coupled with genetic mouse and organoid models, we identified Klf5 as a critical regulator of alveolar epithelial cell fate across the lifespan. During prenatal lung development and alveologenesis, Klf5 enforces alveolar epithelial type 1 (AT1) cell lineage fidelity. While it is dispensable for both adult AT1 and alveolar epithelial type 2 (AT2) cell homeostasis, Klf5 regulates AT2 cell plasticity after injury. more...

(Submitter supplied) Alveolar epithelial type 2 (AT2) cells are facultative progenitor cells that drive adult alveolar regeneration after acute lung injury. Using transcriptomic analyses from in vivo mouse injury models, we define the role of Tfcp2l1 in regulating AT2 cell behavior during lung regeneration.

(Submitter supplied) Alveoli are thin-walled sacs that serve as the gas exchange units of the lung. They are affected in devastating lung diseases including COPD, Idiopathic Pulmonary Fibrosis, and the major form (adenocarcinoma) of lung cancer, the leading cause of cancer deaths. The alveolar epithelium is composed of two morphologically distinct cell types: alveolar type (AT) 1 cells, exquisitely thin cells across which oxygen diffuses to reach the blood, and AT2 cells, specialized surfactant-secreting cells. more...

Analysis of adult alveolar type (AT) 2 and E18 bipotent progenitor (BP) lung cells. During development, AT1 and AT2 cells arise from a BP; after birth, new AT1 cells derive from rare, long-lived, self-renewing mature AT2 cells. Results provide insight into the molecular basis of AT2 self-renewal.

(Submitter supplied) Alveolar type 1 and type 2 cells comprise the epithelial component of the lung alveolus where gas exchange occurs. AT2 cells harbor progenitor activity and can self-renew and differentiate into AT1 cells during homeostasis and after injury. To identify epigenetic pathways that control the AT2-AT1 regenerative response in the lung, we performed an organoid screen using a library of pharmacological epigenetic inhibitors. more...

(Submitter supplied) The Bone Morphogenetic Protein (BMP) signaling pathway functions in lung development and the regeneration of adult tracheal epithelium from basal stem cells. Here, we explore its role in the alveolar region, where Type 2 epithelial cells (AT2s) and Pdgfrα+ Type 2 - associated stromal cells (TASCs) are components of the stem cell niche. We utilize both organoid assays and in vivo alveolar regrowth after pneumonectomy (PNX) - a process requiring proliferation of AT2s and differentiation into Type 1 cells (AT1). more...

(Submitter supplied) Treatment with IL-1b or TNFa enhance the proliferation of alveolar type 2 cells in organoid culture. Here, we examine the downstream mechanisms that enhance AEC2 proliferation after IL-1b and TNFa treatments, we performed RNA-seq analysis of AEC2s isolated from organoids 6 hrs after exposure to either cytokine. We identified 165 differentially expressed genes that were common in both IL-1b and TNFa treated AEC2s compared to saline treated controls.

(Submitter supplied) Lung cancer is the leading cause of cancer deaths worldwide. TP53 tumor suppressor gene mutations occur in 50% of lung adenocarcinomas (LUADs) and are linked to poor prognosis, but how p53 suppresses LUAD development remains enigmatic. We show here that p53 suppresses LUAD by governing cell state, by promoting alveolar type 1 (AT1) differentiation. Using mice expressing oncogenic Kras and null, wild-type, or hypermorphic p53 alleles in alveolar type 2 (AT2) cells, we observed graded effects of p53 on LUAD initiation and progression. more...
