项目摘要

DESCRIPTION (provided by applicant): Current toxicity or pathogenesis studies rely heavily on traditional cell culture methods and animal models. While these systems provide much basic information, a human 3D organ model composed of native cell types interacting in a physiologically relevant way would more closely approximate in vivo conditions. Development of improved in vitro organ models would enable researchers to construct and analyze complex biological systems especially as they relate to organ development, disease pathogenesis, and toxicology and drug discovery. The development of such a model requires identifying the appropriate matrix material, cell types and microenvironment. Our hypothesis is that human embryonic stem or progenitor cells can be cultured on scaffolds to create an in vitro human lung model. It is possible to introduce leukocytes to the system to further mimic the in vivo environment and to study the roles of fibroblasts/myofibroblasts and macrophages/dendritic cells in the development of pulmonary fibrosis. The central hypothesis of this project is that human stem or progenitor cells can be on natural acellular lung or other commercially available scaffolds to create an in vitro human lung model which can be used to study lung disease and the development of fibrosis after microbial infection or exposure to xenobiotic agents. In this project, our aims are to (1) Produce a long term sustainable three dimensional (3D) human pulmonary model and (2) Test the validity of the model using exposure to H5N1, known to cause development of acute conditions and fibrosis in the lung or H1N1 2009 suspected of causing similar but less severe responses. Sham exposure or exposure to circulating strains of influenza A that do not elicit these responses will be used as controls as will addition of neuraminidase inhibitors Tamiflu and Amantidine. In order to produce the best lung model various matrices such as Gelfoam, Matrigel and collagen-IV will be examined for the ability to allow cell adhesion and sustainability. Several matrix materials will be considered, however, acellular (AC) human lung may be the best candidate for a fibrosis model. Recent work in our laboratory has shown this matrix is able to support differentiation of mouse embryonic stem cells toward cells comprising lung tissue with an appropriate morphology. Both AC whole rat trachea-lung and small sections of AC human lung will be tested for efficacy. For a human model, cell sources to be considered include cell lines and primary cells. Among the human cell lines to be trialed are A549 cells (Type II pneumocytes), HUV-EC-C or HUVEC-CS (human umbilical vein endothelial cells developed into a cell line), 13Lu (fetal lung cells) and human embryonic stem cells. Primary and progenitor cells such as HUVEC (primary cells), human amniotic fluid cells, and somatic lung progenitor cells may be used in a supporting role or to populate the matrix. The growth medium will be assessed for efficient proliferation and differentiation of cells into lung tissue.

描述（由申请人提供）：当前的毒性或发病机理研究在很大程度上依赖于传统的细胞培养方法和动物模型。尽管这些系统提供了许多基本信息，但由以生理相关方式相互作用的天然细胞类型组成的人类3D器官模型将在体内条件下更接近近似。改进的体外器官模型的开发将使研究人员能够构建和分析复杂的生物系统，尤其是与器官发育，疾病发病机理以及毒理学和药物发现有关的过程。这种模型的开发需要确定适当的基质材料，细胞类型和微环境。我们的假设是，人类胚胎干或祖细胞可以在脚手架上培养以创建体外人肺模型。可以将白细胞引入系统，以进一步模仿体内环境，并研究成纤维细胞/肌纤维细胞和巨噬细胞/树突状细胞在肺纤维化发展中的作用。该项目的核心假设是人的茎或祖细胞可以在天然细胞的肺或其他商业上可用的脚手架上，以创建一个体外人类肺模型，可用于研究肺部疾病和微生物感染后纤维化的发展或暴露于异生物生物生物生物生物生物生物的纤维化。在该项目中，我们的目的是（1）产生长期可持续的三维（3D）人类肺模型，（2）使用暴露于H5N1进行测试该模型的有效性，已知会导致急性条件和H1N1 2009中的纤维化发展和纤维化，涉嫌涉嫌造成类似但严重的响应。假暴露或暴露于不引起这些反应的流感循环菌株将被用作对照，因为添加了神经氨酸酶抑制剂tamiflu和amantidine。为了生产最佳的肺模型，将检查各种矩阵，例如Gelfoam，Matrigel和胶原蛋白IV，以便能够允许细胞粘附和可持续性。但是，将考虑几种基质材料，但是，细胞（AC）人肺可能是纤维化模型的最佳候选者。我们实验室的最新工作表明，该基质能够支持小鼠胚胎干细胞向包含具有适当形态的肺组织的细胞的分化。 AC全大鼠气管肺和AC人肺的小部分都将进行疗效。对于人类模型，要考虑的细胞源包括细胞系和原代细胞。在要试用的人类细胞系中，有A549细胞（II型肺炎细胞），HUV-EC-C或HUVEC-CS（人脐静脉内皮细胞发展为细胞系），13LU（胎儿肺细胞）和人类胚胎干细胞。原代和祖细胞，例如HUVEC（原代细胞），人羊水细胞和体细胞祖细胞可用于支撑作用或填充基质。将评估生长培养基的有效增殖和细胞分化为肺组织。
