(Submitter supplied) The pulmonary alveolar epithelium which play key role in lung biological function is mainly composed of two types of epithelial cells: alveolar type I (AT1) and type II (AT2) cells. We know very little about developmental heterogeneity of the AT1 cell population. By using 10X genomics “Chromium Single Cell” technology, we performed single-cell RNA-seq (scRNA-seq) analyses of AT1 cells at postnatal day 3 (P3), P15, and P60, along with AT2 cells (P60) in mice. more...

(Submitter supplied) Alveologenesis is the culmination of lung development and involves the correct temporal and spatial signals to generate the delicate gas exchange interface. Using a novel Wnt signaling reporter system, we have identified a Wnt-responsive alveolar epithelial sublineage arising during alveologenesis called the axin2+ alveolar type 2 cell or AT2Aaxin2. The number of AT2Aaxin2 sublineage cells increases substantially during late lung development, revealing a wave of Wnt signaling during alveologenesis. more...

(Submitter supplied) The lung alveolus is the primary site of gas exchange in mammals. Within the alveolus, the alveolar type 2 (AT2) epithelial cell population generates surfactant to maintain alveolar structure and harbors a regenerative capacity to repair the alveolus after injury. We show that a Wnt-responsive alveolar epithelial progenitor (AEP) lineage within the AT2 cell population is critical for regenerating the alveolar niche. more...

(Submitter supplied) Molecular programs that mediate normal cell differentiation are required for oncogenesis and tumor cell survival in certain cancers. How cell-lineage-restricted genes specifically influence metastasis is poorly defined. In lung cancers, we uncovered a transcriptional program that is preferentially associated with distal airway epithelial differentiation and lung adenocarcinoma (ADC) progression. This program is regulated in part by the lineage transcription factors GATA6 and HOPX. more...

(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) We perform time-series global transcriptomic profiling of a directed differentiation protocol for generating alveolar epithelial type II cells (AEC2s) from pluripotent stem cells (PSCs). We analyzed 3 different timepoints in the RUES2 differentiation: 1) Day 0 undifferentiated cells, 2) Day 15 lung progenitors highly enriched in NKX2-1+ cells by CD47hi/CD26lo sorting, and 3) the outgrowth of these purified progenitors in 3D culture sorted again on Day 35 based on SFTPCtdTomato+ and SFTPCtdTomato- gating. more...

(Submitter supplied) The alveolar type 1 (AT1) cell covers >95% of the gas exchange surface and is extremely thin to facilitate passive gas diffusion. The development of this highly specialized cell is poorly understood including fundamental questions regarding cell number and morphology. Using new molecular stereology and single cell imaging methods, we show that AT1 cells develop via a non-proliferative two-step process while maintaining proliferative potential. more...

(Submitter supplied) The lung alveolus is the functional unit of the respiratory system required for gas exchange. During the transition to air breathing at birth, biophysical forces are thought to shape the emerging tissue niche. However, the intercellular signaling that drives these processes remain poorly understood. Applying a multimodal approach, we identify alveolar type 1 (AT1) epithelial cells as a distinct signaling hub. more...

(Submitter supplied) HOPX is an atypical homeodomain-containing protein lacking DNA-binding capacity. Via interaction with transcription factors, particularly SRF, it has critical functions in the development of various tissues. Here we unveil an essential regulatory role of HOPX in human T lymphocytes. Human CD8+ T cells expressed all three isoforms (a, b, and c) of HOPX wherein HOPXb was the predominant one. HOPX expression was induced by TCR activation and increased from TN to TEM cells. more...
