Work in my lab is focused upon creating tissue models mimicking fluid forces aspects of the in vivo state of various tissues. These models can be used for testing cell and tissue physiology, discovering key modulators of cell function, and developing a mechanistic understanding of tissue function under flow. We have translated discoveries and platform technologies based on these concepts with submission of multiple patent applications, formation of 4 companies, and multiple trainees employed in the engineering and technology sectors in the past five years. Over the next five to ten years we propose to continue developing platform technologies and knowledge in mechanobiology to facilitate advances in health and technology. ***Short-term goals (5 years): 1) Identify key modulators of flow-mediated gene expression in blood vessel cells. 2) Develop new imaging and computational methods to quantify in vivo fluid flows and tissue characteristics. 3) Create normal breast tissue model and quantify gene expression and cell function changes in the flow environment. ***Long-term goals (5-10 years): 1) Develop a mechanistic description of endothelial and epithelial gene expression and function in a flow environment. 2) Correlate endothelial and epithelial flow responses to those in other cell types to map how fluid flow may be used as a stimulant that tunes' cells for the creation or maintenance of healthy tissues. 3) Identify molecular signatures in fluids (such as blood or milk) that can be used to characterize health of an individual. ***Significance and Impact: The innovation in this research program is 1) elucidation of mechanisms of health promotion in fluid flow environments, 2) identification of molecular signatures associated with fluid flow, and 3) development of testing platforms for specific investigation of blood vessel and breast health. This project will identify fluid force sensitive molecular regulators that will aid in the understanding of normal human vascular and breast tissue function. This information will lead directly to a stimulus-function relationship that will be used to predict how blood vessels and breast tissue maintain healthy function, including the key factors driving physiological responses. These relationships will enable a new paradigm in understanding health, and will provide a way to test new therapeutics or devices and identify healthy molecular signatures.***Training: Undergraduate students, graduate students (PhD and MSc), and a postdoctoral fellow will perform the research and be part of collaborative teams advancing knowledge and developing technologies related to fluid force effects on cells; gaining valuable skills for recruitment into the biotechnology, medical device and related industries.

我实验室的工作重点是创建组织模型，模拟各种组织在体内状态的流体力方面。这些模型可用于测试细胞和组织生理学，发现细胞功能的关键调节器，并发展对流动下组织功能的机械理解。在过去的五年里，我们通过提交多项专利申请，成立了4家公司，并在工程和技术部门雇用了多名学员，将基于这些概念的发现和平台技术转化为技术。在接下来的五到十年里，我们建议继续开发机械生物学的平台技术和知识，以促进卫生和技术的进步。*短期目标(5年)：1)确定血管细胞中流动介导的基因表达的关键调节因子。2)发展新的成像和计算方法来量化体内液体流动和组织特征。3)建立正常乳腺组织模型，定量检测流动环境中基因表达和细胞功能的变化。*长期目标(5-10年)：1)发展对内皮细胞和上皮细胞基因在流动环境中的表达和功能的机械描述。2)将内皮细胞和上皮细胞的血流反应与其他细胞类型的反应相关联，以绘制出液体流动如何被用作刺激细胞以创建或维持健康组织的图。3)确定液体(如血液或牛奶)中可用于表征个人健康状况的分子特征。*意义和影响：本研究项目的创新之处在于：1)阐明流体流动环境中促进健康的机制，2)识别与流体流动相关的分子特征，3)开发专门研究血管和乳房健康的测试平台。该项目将确定流体力敏感的分子调节器，这将有助于了解正常的人体血管和乳房组织功能。这些信息将直接导致刺激-功能关系，用于预测血管和乳房组织如何保持健康功能，包括驱动生理反应的关键因素。这些关系将实现理解健康的新范式，并将提供一种测试新疗法或设备和识别健康分子签名的方法。*培训：本科生、研究生(博士和硕士)和一名博士后将进行研究，并成为合作团队的一员，促进与流体作用力对细胞的影响相关的知识和技术的发展；获得宝贵的技能，以招募到生物技术、医疗设备和相关行业。
