项目摘要
Principal Investigator/Program Director: Haussler, David
Project Summary
The focus of our CEGS Center for Live Cell Genomics is to build new methodology and capacity for
large-scale, long-term, inexpensive, modular, customizable, shared, Internet-of-Things- controlled, reproducible
live cell culture and tissue-based experimental genomics disease models. Tissue models include traditional cell
culture as well as organoid and primary tissue explants obtained from surgery or biopsy. A particular focus is
the integration of organoid factories that support tissue growth and maintenance with external and on-chip
electro- optofluidic analytical modules to become part of an ecosystem that is modeled after open- source
software. This system will use commodity sensors, cameras, and computers linked in platforms that are flexibly
designed using simple, widely available techniques potentially in order to stimulate rapid innovation in
experimental platforms for tissue culture. This novel technology will allow us to address major scientific issues
in neurodevelopment and pediatric cancer. These include questions about what genes contribute to human
brain development, or what specific molecular pathways are disrupted in individual pediatric cancer cases.
Over the first year of our project, it has become clear that in order to advance our research agenda on both the
scientific and technological sides we require an established, multi-modal nanoparticle analysis method.
Specifically, we are facing two challenges. We need to be able to assess the nanoscale extracellular vesicles
(EVs), specifically exosomes, that are being produced in our organoid factories as a measure of organoid cell
types, metabolism, and health. As these measurements need to be carried out frequently over long periods of
time, a fast and relatively easy-to-use technique is required. Secondly, in order to develop optofluidic devices
that can carry out measurements on individual EVs and exosomes and their molecular content, we need to be
able to establish ground truth references against which the performance of these devices can be compared. To
this end, we are requesting supplemental funding to acquire a Nanoparticle Tracking Analyzer (NTA)
instrument that will provide these capabilities throughout our project. An NTA is a unique instrument that
provides multi-modal analysis on populations of biological and inorganic nanoparticles. Pertinent capabilities
include buffer calibration, measurement of EV concentration and size distribution, surface charge
measurements, assessment of labeling efficiencies, and more. As such, an NTA is uniquely suited for our
requirements and will dramatically accelerate the progress of our research as well as expand its outcomes.

项目摘要
我们CEGS活细胞基因组中心的重点是建立新的方法和能力
大规模、长期、廉价、模块化、可定制、共享、物联网控制、可复制
活细胞培养和基于组织的实验基因组学疾病模型。组织模型包括传统细胞
培养以及从手术或活检中获得的器官和初级组织外植体。一个特别的焦点是
支持组织生长和维护的有机工厂与外部和芯片上的集成
电光流体分析模块将成为模仿开源的生态系统的一部分
软件。该系统将使用商用传感器、摄像头和连接在灵活平台上的计算机
使用简单、广泛可用的技术进行设计,潜在地刺激快速创新
组织培养的实验平台。这项新技术将使我们能够解决重大科学问题
神经发育和儿科癌症。这些问题包括哪些基因对人类有贡献。
在个别的儿科癌症病例中,大脑发育或哪些特定的分子通路被扰乱。
在我们项目的第一年,很明显,为了推进我们在两个方面的研究议程
科学和技术方面,我们需要一种成熟的、多模式的纳米颗粒分析方法。
具体地说,我们面临着两个挑战。我们需要能够评估纳米级的细胞外小泡
(EVS),特别是外切体,在我们的有机工厂生产,作为衡量有机细胞的指标
类型、新陈代谢和健康。因为这些测量需要在长时间内频繁地执行
随着时间的推移,需要一种快速且相对易于使用的技术。其次,为了发展光流控器件
可以对单个电动汽车和外切体及其分子含量进行测量,我们需要
能够建立可与这些设备的性能进行比较的基本事实参考。至
为此,我们正在申请补充资金,以获得纳米颗粒跟踪分析仪(NTA)
将在我们的整个项目中提供这些功能的仪器。NTA是一种独特的工具,它
提供对生物和无机纳米粒子群体的多模式分析。相关能力
包括缓冲器校准、电动汽车浓度和尺寸分布测量、表面电荷
测量、标签效率评估等。因此,NTA特别适合我们的
这将极大地加快我们的研究进展并扩大其成果。
