Project description:Co-cultures of lung epithelium and mesenchyme are useful tools to study epithelial-mesenchymal crosstalk in lung development and disease. However, many previous attempts to generate such co-cultures have yielded poor juxtaposition between the epithelial and the mesenchymal lineage. In addition, induced pluripotent stem cell (iPSC)-derived co-cultures often contain generic mesenchyme that is not necessarily lung-specific. We sought to establish co-cultures of purified mouse iPSC-derived lung-specific mesenchyme and iPSC-derived lung epithelial progenitors. We used a mouse iPSC line carrying a lung mesenchyme-specific reporter/tracer (Tbx4-LERGFP) to generate lung mesenchymal progenitors by directed differentiation via a lateral plate mesodermal progenitor state (induced lung mesenchyme, iLM). In parallel we differentiated a mouse embryonic stem (ES) cell line carrying a Nkx2-1mCherry reporter into lung epithelial progenitor cells using our established directed differentiation protocol. We then combined the purified lung epithelial and mesenchymal progenitor cells and co-cultured them in distal or proximal differentiation media for 1 week on Matrigel. We find that cells self-organize into complex 3-dimensional organoids with closely juxtaposed epithelial and mesenchymal cells. Furthermore, co-culture affects the molecular phenotype of both lineages. Our iPSC-derived co-culture model can provide an inexhaustible source of cells for studying lung development, modeling diseases, and developing therapeutics.

Project description:Mesenchymal stem/stromal cells (MSCs) are multipotent cells that can differentiate into a variety of cell types forming connective tissue and skeleton, and are essential participants in the development of all organs. However, MSC precursors remain largely unknown. In human embryonic stem cells (hESCs) directed to mesendodermal differentiation through coculture with OP9 stromal cells, we identified a population of mesodermal cells by surface expression of apelin receptor (APLNR1). APLNR+ cells were enriched with precursors generating compact spheroid colonies in semisolid suspension culture. Being formed by single cells, these colonies consisted of a uniform population of mesenchymal cells with a transcriptional profile representative of embryonic mesenchyme originating from lateral plate/extraembryonic mesoderm. Mesenchymal colony formation required serum-free medium and FGF2 as a colony-forming factor, could be significantly enhanced by PDGF-BB, but suppressed by VEGF. When transferred to the adherent cultures in serum-free medium with FGF2, individual colonies gave rise to multipotential mesenchymal cell lines with typical phenotype (CD146+CD105+CD73+CD31-CD43-CD45-), differentiation (chondro-, osteo-, and adipogenesis) and proliferation (>80 doublings) potentials. Consistent with lineage-restricted differentiation pattern, neither endothelial nor hematopoietic cells could be produced from adherent mesenchymal cultures, however endothelial cells could be derived from mesenchymal colonies in the early days of colony-forming culture suggesting that mesenchymal cells arose from cells with primary angiogenic potential (mesangioblasts). Together these studies identified mesangioblasts as the earliest clonogenic mesenchymal precursors at this stage of their specification from mesoderm. This set (11 samples) of expression data is sequential stages of MSC development from hESCs (H1), namely ALPNR+ mesodermal precursors isolated on day 2 and day 3 differentiation, mesangioblast (MB) cores (Day 2 H1-derived cores), hemangioblast (HB) cores (day 3 H1-derived cores), mesangioblast (MB) and hemangioblast (HB) colonies, and colony-derived MSC lines at passage 1 and 5.

Project description:Congenital diaphragmatic hernia (CDH) is a common and severe congential malformation characterized by defects in diaphragm, lung, and pulmonary vascular developent. Despite the frequency and severity of CDH, the underlying developmental mechanisms are not understood. We identified SIN3A loss of function sequence variants in two patients with CDH. To understand the genetic and developmental mechanisms of CDH, we generated Sin3a conditional knockout mice that lack Sin3a expression in the lung mesenchyme. SIN3A has been shown to play a critcal role during development, directing cell lineage specification and cell cycling. We found that loss of SIN3A resulted in impaired mesenchymal cell differentiation from bulk lung transcriptomic analysis in Sin3a CKO mice. To investigate the impact of loss of SIN3A in mesenchymal cell differentation, we performed fluorescent activated cell sorting (FACS) to isolate cells that underwent recombination of Sin3a. We then performed single-cell transcriptomic analysis on sorted mesenchymal cells from embryonic day 16 (E16) Sin3a CKO and control lungs. In this dataset are expression data from FACS-isolated recombined lung mesenchymal cells of Sin3a CKO and control mice. Sin3a CKO mice have conditional deletion of Sin3a in the lung mesenchyme directed by Tbx4rtta; tetocre (Tbx4rtta; tetocre; Sin3a flox/flox CKO). Control mice are heterozygous for Sin3a in the lung mesenchyme (Tbx4rtta; tetocre; Sin3a flox/WT). These data were used to identify transcriptional changes due to loss of Sin3a in the lung mesenchyme.

Project description:Most vertebrate organs are composed of epithelium surrounded by support and stromal tissues formed from mesenchyme cells, which are not generally thought to form organized progenitor pools. Here we use clonal cell labeling with multicolor reporters to characterize individual mesenchymal progenitors in the developing mouse lung. We observe a diversity of mesenchymal progenitor populations with different locations, movements, and lineage boundaries. Airway smooth muscle (ASM) progenitors map exclusively to mesenchyme ahead of budding airways. Progenitors recruited from these tip pools differentiate into ASM around airway stalks; flanking stalk mesenchyme can be induced to form an ASM niche by a lateral bud or by an airway tip plus focal Wnt signal. Thus, mesenchymal progenitors can be organized into localized and carefully controlled domains that rival epithelial progenitor niches in regulatory sophistication. Mesenchyme was microdissected from e11.5 and e12.5 lung branch tips and stalks and profiled directly. Another set of stalk dissections were cultured in either control media or media containing Wnt1. All experiments done in duplicate.

Project description:Osteoblasts arise from bone-surrounding connective tissue containing tenocytes and fibroblasts. Lineages of these cell populations and mechanisms of their differentiation are not well understood. Screening enhancer-trap lines of zebrafish allowed us to identify Ebf3 as a transcription factor marking tenocytes and connective tissue cells in skeletal muscle of embryos. Knockout of Ebf3 in mice had no effect on chondrogenesis but led to sternum ossification defects as a result of defective generation of Runx2+ pre-osteoblasts. Conditional and temporal Ebf3 knockout mice revealed requirements of Ebf3 in the lateral plate mesenchyme cells (LPMs), especially in tendon/muscle connective tissue cells, and a stage-specific Ebf3 requirement at embryonic day 9.5-10.5. Upregulated expression of connective tissue markers, such as Egr1/2 and Osr1, increased number of Islet1+ mesenchyme cells, and downregulation of gene expression of the Runx2 regulator Shox2 in Ebf3-deleted thoracic LPMs suggest crucial roles of Ebf3 in the onset of lateral plate mesoderm differentiation towards osteoblasts forming sternum tissues.
