Generation of Alveolar Epithelial Spheroids via Isolated Progenitor Cells from Human Pluripotent Stem Cells

چکیده
No methods for isolating induced alveolar epithelial progenitor cells (AEPCs) from human embryonic stem cells (hESCs) and induced pluripotent stem cells (hiPSCs) have been reported. Based on a study of the stepwise induction of alveolar epithelial cells (AECs), we identified carboxypeptidase M (CPM) as a surface marker of NKX2-1(+) "ventralized" anterior foregut endoderm cells (VAFECs) in vitro and in fetal human and murine lungs. Using SFTPC-GFP reporter hPSCs and a 3D coculture system with fetal human lung fibroblasts, we showed that CPM(+) cells isolated from VAFECs differentiate into AECs, demonstrating that CPM is a marker of AEPCs. Moreover, 3D coculture differentiation of CPM(+) cells formed spheroids with lamellar-body-like structures and an increased expression of surfactant proteins compared with 2D differentiation. Methods to induce and isolate AEPCs using CPM and consequently generate alveolar epithelial spheroids would aid human pulmonary disease modeling and regenerative medicine.

Specification of Hemato-Endothelial-Like Structures and Generation of Hematopoietic Progenitor Cells from Human Pluripotent Stem Cells
Background and purpose: Human pluripotent stem cells (hPSCs) with the ability to differentiate into adult cells have provided a new perspective for treatment of some diseases. But, the efficiency of differentiation methods to generate hematopoietic progenitor cells (HPCs) is faced with multiple challenges. In the present study, we investigated the formation of hemato-endothelial-like structure...
متن کاملDirected Induction of Functional Multi-ciliated Cells in Proximal Airway Epithelial Spheroids from Human Pluripotent Stem Cells.
Multi-ciliated airway cells (MCACs) play a role in mucociliary clearance of the lung. However, the efficient induction of functional MCACs from human pluripotent stem cells has not yet been reported. Using carboxypeptidase M (CPM) as a surface marker of NKX2-1(+)-ventralized anterior foregut endoderm cells (VAFECs), we report a three-dimensional differentiation protocol for generating proximal ...
متن کاملAlpha-Tocopherol increases the proliferation of induced pluripotent stem cell derived neural progenitor cells
In addition to its antioxidant effect, Vitamin E or α–tocopherol is suggested to enhance remyelination in the animal model of non-inflammatory demyelination. In this study, the possible proliferative effect of vitamin E on human- induced pluripotent stem cell-derived neural progenitors (hiPS-NPs) and the underlying mechanisms were investigated in vitro. NPs were induced from iPS cells via 3 ste...
متن کاملA Quick update from the Past to Current Status of Human Pluripotent Stem Cell-derived Hepatocyte culture systems
Pluripotent stem cells (PSCs) may be offered as an unlimited cell source for the hepatocyte generation. The generation of hepatocytes from stem cells in vitro would provide an alternative cell source for applications in drug discovery and cell transplantation. In this review, we discuss different approaches to generate pluripotent stem cell-derived hepatocytes, advantages, limitations for each ...
