(Submitter supplied) We investigated whether in vitro expansion of human alveolar epithelial type II cells is possible. We found that human endogenous human alveolar epithelial type II cells can be cultured and passaged. The culture system enabled retroviral gene transduction into human alveolar epithelial type II cells. We performed RNA sequencing of human alveolar epithelial type II cells transduced with mutant surfactant protein C or control vector.

(Submitter supplied) We performed transcriptomic profiling of cells derived from human pluripotent stem cells (PSCs) using distal lung directed differentiation protocol previously described to generate alveolar type II epithelial-like cells (iAEC2s). We used the RUES2-STAG human embryonic stem cell line containing bi-fluorescently targeted ABCA3:GFP knock-in fusion reporter and SFTPCtdTomato knock-in reporter to potentially identify heterogenous iAEC2 populations and determine their gene expression profiles. more...

(Submitter supplied) We performed transcriptomic profiling of cells derived from human induced pluripotent stem cells (iPSCs) using our previously described distal lung directed differentiation protocol to generate alveolar epithelial type 2 cells (iAEC2s). We used the SPC2 human iPSC line and specifically the SPC2-ST-B2 (SFTPCtdT/WT) and SPC2-ST-C11 (SFTPCI73T/tdT) clones containing a SFTPCtdTomato knock-in reporter. SFTPCtdTomato+ cells were sorted on day 51 of differentiation and maintained without further sorting in self-renewing 3D alveolosphere cultures passaged approximately every 2 weeks through day 114. more...

(Submitter supplied) Specific surface marker for NKX2-1+ VAFECs may be helpful for isolating a homogeneous population of alveolar epithelial progenitor cells and distinguishing the differentiation from a thyroid lineage to a lung lineage. In order to identify specific markers of VAFECs, a microarray analysis was performed to compare the global gene expression patterns between AFECs and VAFECs in 201B7 hiPSCs. We hypothesized that NKX2-1+ cells could be purified by sorting CPM+ VAFECs. more...

(Submitter supplied) We performed transcriptomic profiling of freshly isolated primary adult human alveolar epithelial type 2 cells (AEC2s), their isogenic cultured progeny, and human induced pluripotent stem cell-derived AEC2s (iAEC2s). Distal lung preparations from adult donor lung explants from two individuals were cryopreserved using methods we have previously described. Primary AEC2s were purified using fluorescence activated cell sorting (FACS) to isolate cells co-expressing EPCAM and HTII-280. more...

(Submitter supplied) Idiopathic pulmonary fibrosis (IPF) is a devastating chronic lung disease, where lung function decline is gradual and the overall prognosis of patients with IPF is poor with a median survival after diagnosis of approximately 3.8 years. Growing evidence points to the fundamental role for the mitochondrion in alveolar type 2 (AEC2) cell dysfunction in the pathogenesis of IPF. Additionally, single-cell RNA sequencing (RNA-Seq) recently identified MFN2 mRNA as significantly upregulated in AEC2 cells from patients with IPF, suggesting a role for mitochondrial fusion in AEC2 cells and the development of IPF. more...

(Submitter supplied) Alveolar epithelial type II (ATII)-like cells can be generated from murine embryonic stem cells (ESCs), although to date, no robust protocols applying specific differentiation factors are established. We hypothesized that the keratinocyte growth factor (KGF), an important mediator of lung organogenesis and primary ATII cell maturation and proliferation, together with dexamethasone, 8-bromoadenosine-cAMP, and isobutylmethylxanthine (DCI), which induce maturation of primary fetal ATII cells, also support the alveolar differentiation of murine ESCs. more...

(Submitter supplied) Gas exchange in the mammalian lung occurs in the alveolar sacs lined by epithelial cells that form a barrier allowing effective oxygen diffusion. Telomere syndromes have their most common manifestation in degenerative disease of the alveoli, both pulmonary fibrosis and emphysema. We tested the role of telomere dysfunction by inducing deletion of the telomere binding protein Trf2 in type 2 alveolar epithelial cells (AEC2s) that both express the gene encoding surfactant protein C and constitute the regenerative compartment of the alveolar epithelium. more...

(Submitter supplied) The alveolar epithelial cells are known producers of basement membrane components of the ECM, we hypothesize that they may also contribute substantially to remodeling of interstitial ECM in the alveolar compartment in chronic lung diseases such as chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF). Primary human alveolar type II epithelial cells (AECII) were isolated from human lungs without lung disease or with end stage COPD, using the surface marker HT2-280. 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) 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.
