(Submitter supplied) The lung microvasculature is essential for gas exchange and commonly considered homogeneous. We show that Vascular endothelial growth factor A (Vegfa) from the epithelium specifies a distinct endothelial cell (EC) population in the postnatal mouse lung. Vegfa is predominantly expressed by alveolar type 1 (AT1) cells and locally required to specify a subset of ECs. Single cell RNA-seq identified 15~20% lung ECs as transcriptionally distinct and marked by Carbonic anhydrase 4 (Car4), which are specifically lost upon epithelial Vegfa deletion. more...

(Submitter supplied) Pulmonary endothelial cells are an essential component of the lung alveolus, where they assist in integrating this niche with the cardiovascular system to perform gas exchange with the external environment. Despite its importance, the extent and function of endothelial cell heterogeneity within the lung remains incompletely understood. Using single-cell analytics, we show that multiple vascular endothelial cell populations exist in the mouse lung, including macrovascular endothelium (maECs), microvascular endothelium (miECs), and a new population we have termed regulator endothelium (RECs). more...

(Submitter supplied) Alveolar formation increases the surface area for gas-exchange and is key to the physiological function of the lung. Alveolar epithelial cells, myofibroblasts and endothelial cells undergo coordinated morphogenesis to generate epithelial folds (secondary septa) within the saccules to form alveoli. A mechanistic understanding of alveologenesis remains incomplete. We found that the planar cell polarity (PCP) pathway is required in both alveolar epithelial cells and myofibroblasts for alveologenesis. 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) Type IV collagen is the main component of the basement membrane which gives strength to the blood-gas barrier. In avians the formation of the blood-gas barrier happens rapidly and before hatching. We have performed a microarray expression analysis in late chick lung development and found that COL4A1 and COL4A2 were among the most significantly upregulated genes during the formation of the avian blood-gas barrier. more...

(Submitter supplied) The extraordinarily thin alveolar type 1 (AT1) cell constitutes nearly the entire gas exchange surface and allows passive diffusion of oxygen into the blood stream. Despite such an essential role, the transcriptional network controlling AT1 cells remains unclear. Using cell-specific knockout mouse models, genomic profiling, and three-dimensional imaging, we found that NK Homeobox 2-1 (NKX2-1) is expressed in AT1 cells and is required for the development and maintenance of AT1 cells. more...

(Submitter supplied) Analysis of gene expression and alternative splicing changes in mouse lungs at different developmental time-points (E15.5, E18.5, P5, P8) was performed through RNAseq. We performed 101 nt paired-end RNAseq using HiSeq 4000 on triplicate samples. We obtained an average of 59.8 million reads per sample. The sequence reads that passed quality filters were analyzed at the transcript and at the alternative splicing events level using using D For gene expression analysis, the ~56.8 M raw reads generated per sample were uniquely mapped to the mm10 assembly and annotated to the Gencode vM14 transcriptome using TopHat2, with Bowtie2. 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) 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) Following acute injury, the capillary vascular bed in the lung must be repaired to reestablish gas exchange between pulmonary endothelial cells (ECs) lining these vessels and the alveolar epithelium. However, the factors that control EC stress response and drive regeneration of pulmonary capillaries remain incompletely understood. Viral infections such as influenza and COVID-19 may indirectly damage lung vasculature through loss of epithelial gas exchange partners or through signaling from infiltrating immune cells. more...

(Submitter supplied) Aims: Coronary vasculature formation is a critical event during cardiac development, essential for heart function throughout perinatal and adult life. However, current understanding of coronary vascular development has largely been derived from transgenic mouse models. The aim of this study was to characterise the transcriptome of the human fetal cardiac endothelium using single-cell RNA sequencing (scRNA-seq) to provide critical new insights into the cellular heterogeneity and transcriptional dynamics that underpin endothelial specification within the vasculature of the developing heart. more...
