ABSTRACT Endometriosis affects an estimated 176 million women and girls of reproductive age, worldwide, causing chronic pelvic pain and infertility. Despite the fact that most women experience retrograde menstruation, only 10% of women present with this condition, the underlying reasons for which are still unclear. The primary objective of this project is to explore the genetic basis for endometriosis pathophysiology through the application of innovative technologies and model systems. We have successfully produced induced pluripotent stem cells (iPSC) derived from blood cells of women with endometriosis and developed a novel microfluidic device capable of co-culturing cells and tissues. In this study, we aim to differentiate iPSCs into endometrial epithelial and stromal cells, as well as macrophages, and compare their behavior to that of cells derived from women without the condition. By using the microfluidic device, we will construct an endometriosis-immune chip that will enable us to investigate the interaction of endometrial cells with macrophages from endometriosis. Furthermore, we will conduct a comprehensive analysis of DNA variants in the iPSC lines and correlate them with gene expression and cell function, providing a comprehensive, unbiased, and global perspective of inherent differences in endometriosis cells. These cutting-edge technologies will allow us to explore previously unexplored areas of research, offering significant insights into endometriosis and advancing the field of endometriosis research considerably.

抽象的 子宫内膜异位症影响着全世界约 1.76 亿育龄妇女和女童，导致慢性子宫内膜异位症 骨盆疼痛和不孕。尽管大多数女性都会经历月经逆行，但只有 10% 的女性会经历月经逆行。 女性出现这种情况，其根本原因尚不清楚。主要目标 该项目旨在通过应用创新技术探索子宫内膜异位症病理生理学的遗传基础 技术和模型系统。我们已成功生产出诱导多能干细胞（iPSC） 从患有子宫内膜异位症的女性的血细胞中提取，并开发了一种能够共培养的新型微流体装置 细胞和组织。在这项研究中，我们的目标是将 iPSC 分化为子宫内膜上皮细胞和基质细胞，以及 作为巨噬细胞，并将它们的行为与来自没有这种情况的女性的细胞的行为进行比较。通过使用 通过微流体装置，我们将构建一个子宫内膜异位症免疫芯片，使我们能够研究 子宫内膜细胞与子宫内膜异位症巨噬细胞的相互作用。此外，我们还将开展 全面分析 iPSC 系中的 DNA 变异，并将其与基因表达和细胞相关联 功能，提供子宫内膜异位症固有差异的全面、公正和全球视角 细胞。这些尖端技术将使我们能够探索以前未探索的研究领域，提供 对子宫内膜异位症的重要见解并大大推进子宫内膜异位症研究领域。
