DESCRIPTION (provided by applicant): Mesothelial cells have been found to be pivotal in tumor metastasis, peritoneal dialysis, and inflammatory response. These cells are specialized epithelial cells that line the peritoneal, pericardial, and pleural cavities and internal organs presenting a barrier to invading organisms and physical damage. Ovarian tumor attachments occur through cancer cells binding to mesothelial cells and migrating into the surrounding tissue and vasculature. Peritoneal dialysis relies on the intact transport function of mesothelial cells to allow transfer of waste products from the underlying vasculature to the dialysis fluid in the peritoneal cavity. Host response to peritoneal infection is mediated by the inflammatory cascade initiated and cytokines release by peritoneal mesothelial cells. Research into the biology of mesothelial cells continues with the goal of developing methods to provide more effective treatments for disease. Currently, there are no commercial sources of these cells in the U.S. which requires researchers to isolate and characterize the cells on their own. This process is time consuming, requires access to human tissue, and introduces variation in the preparation and quality of the cells. Zen-Bio will address this need by providing a well characterized mesothelial cell culture system to the research community. Phase I of this project focused solely on generating an optimized primary human mesothelial cell system. Isolation and propagation optimization was achieved by systematically modifying aspects of existing protocols to enhance viable cell yields while minimizing population doublings. The ultimate goal of this proposed Phase II application is to further the commercial development to produce a fully validated, commercially available human mesothelial cell system. In addition, we will develop a suite of mesothelial cell-based assays that are applicable to several therapeutic areas. Aim I is to analyze the cytokine and gene expression changes during mesothelial cell transdifferentiation (epithelial to mesenchymal transition). Aim II is to establish mesothelial cell contract services at Zen-Bio. These services include analysis of cytokine secretion, gene expression, tumor cell-mesothelial cell interaction, and cytotoxicity. Multiple product offerings are expected from this proposal: a primary human mesothelial cell system, support media and reagents, contract assay services, and kits for mesothelial cell research. PUBLIC HEALTH RELEVANCE: At the completion of this project, a commercially available, fully characterized primary human mesothelial cell system and support reagents will be offered to researchers. The accessibility of this currently unavailable system will provide wider opportunity to investigate novel methods to inhibit ovarian tumor attachment, prolong the utility of peritoneal dialysis, and treat peritonitis.

描述（由申请人提供）：间皮细胞已被发现在肿瘤转移、腹膜透析和炎症反应中起关键作用。这些细胞是特化的上皮细胞，排列在腹膜、心包、胸膜腔和内部器官上，对入侵的生物体和物理损伤形成屏障。卵巢肿瘤的附着是通过癌细胞与间皮细胞结合并迁移到周围组织和脉管系统中发生的。腹膜透析依赖于间皮细胞完整的转运功能，允许废物从底层血管系统转移到腹膜腔的透析液中。宿主对腹膜感染的反应是由腹膜间皮细胞引发的炎症级联反应和细胞因子释放介导的。对间皮细胞生物学的研究仍在继续，目标是开发方法，为疾病提供更有效的治疗。目前，这些细胞在美国没有商业来源，这需要研究人员自己分离和表征细胞。这个过程耗时，需要接触人体组织，并且在细胞的制备和质量上存在差异。Zen-Bio将通过向研究界提供具有良好特征的间皮细胞培养系统来满足这一需求。该项目的第一阶段专注于生成优化的人间皮细胞系统。分离和繁殖优化是通过系统地修改现有协议的各个方面来实现的，以提高活细胞产量，同时最大限度地减少人口翻倍。该II期申请的最终目标是进一步商业化开发，以生产一种完全有效的、商业上可用的人类间皮细胞系统。此外，我们将开发一套基于间皮细胞的检测方法，适用于多个治疗领域。目的分析间皮细胞转分化过程中细胞因子和基因表达的变化。目标二是在Zen-Bio建立间皮细胞合同服务。这些服务包括细胞因子分泌、基因表达、肿瘤细胞-间皮细胞相互作用和细胞毒性分析。该提案预计将提供多种产品：初级人间皮细胞系统、支持介质和试剂、合同分析服务以及间皮细胞研究试剂盒。公共卫生相关性：在该项目完成后，将向研究人员提供一种市售的、完全表征的原代人间皮细胞系统和支持试剂。该系统的可及性将为研究抑制卵巢肿瘤附着、延长腹膜透析的效用和治疗腹膜炎的新方法提供更广泛的机会。
