PI name: K.J. Burg Institution: Clemson University Proposal Number: 0736007 EFRI-CBE: Emerging Frontiers in 3-D Breast Cancer Tissue Test Systems AbstractThe vision for this project is to develop and demonstrate a new, integrative means of studying the complex behavior of cancer cells in breast tissue. The approach centers on the goal of building an in vitro engineered tissue structure that reproduces the in vivo behavior of the normal and cancerous cells and allows manipulation of environmental parameters to build cause and affect models. Specifically, the end-point of the proposed work will be mathematical relationships describing breast cancer cellular and biomolecular behavior as interactive functions of oxygen level and tissue stiffness, and thus an increased understanding of disease mechanisms. The proposed approach will require development of new experimental and analytical tools to fabricate tissues of hierarchical structure and to assess cell behavior within this framework. The key tools to be developed include a 3D tissue fabrication system, realistic mathematical models to relate cancer cell migration and proliferation with tissue oxygen and stiffness levels, and a novel nanoparticle oxygen sensor.This project will result in the development of a 3D fabrication system and statistical methodology capable of building tissue in repeatable manner. That is, the fabricated tissue may be used as a personalized diagnostic with which to optimize existing therapeutics, develop new drugs, and develop new vaccines. The cross-pollination of ideas and methods between animal science, biology, chemistry, engineering, clinical medicine, and statistics that will result from this proposed work represents a unique training opportunity for the Investigators. Participation on the proposed multi-disciplinary team will provide individual investigators new insights into their own field. Students involved in the proposed program will be immersed in a technically diverse environment including scientists, engineers, and clinicians, and will hone many skills crucial to the 2020 engineer or scientist, including communication, leadership, and teamwork. Through a carefully crafted educational rubric as well as community outreach program, a diverse population of students (K-postgraduate) and educators (K-12) will be engaged.

PI名称：K.J。 Burg Institution：Clemson University的建议编号：0736007 EFRI-CBE：3-D乳腺癌组织测试系统中的新兴边界摘要该项目的视野是开发和展示一种研究癌细胞在乳腺组织中的复杂行为的新型，综合手段。该方法集中在建立体外工程组织结构的目标上，该组织结构重现了正常和癌细胞的体内行为，并允许操纵环境参数以构建原因和影响模型。具体而言，拟议工作的终点将是数学关系，将乳腺癌细胞和生物分子行为描述为氧气和组织僵硬的互动功能，从而增加对疾病机制的理解。所提出的方法将需要开发新的实验和分析工具，以制造层次结构的组织并在此框架内评估细胞行为。要开发的关键工具包括一个3D组织制造系统，将癌细胞迁移和增殖与组织氧和刚度水平相关联的现实数学模型，以及一种新型的纳米颗粒氧气传感器。这将导致3D制造系统的开发以及能够以可重复方式建立组织的统计方法。也就是说，制造的组织可以用作个性化诊断，可以通过该诊断来优化现有的治疗剂，开发新药并开发新的疫苗。动物科学，生物学，化学，工程，临床医学和统计数据之间的思想和方法的交叉授粉将为研究人员提供独特的培训机会。参与拟议的多学科团队将为个人调查人员提供新的见解。参与该计划的学生将沉浸在技术多样化的环境中，包括科学家，工程师和临床医生，并将磨练对2020年工程师或科学家至关重要的许多技能，包括沟通，领导力和团队合作。通过精心制作的教育标题以及社区外展计划，将订婚多样化的学生（K-Postgradgradure）和教育工作者（K-12）。
