项目摘要

Project Summary Single cell RNA-sequencing (scRNA-seq) has enabled researchers to investigate a wide array of biological processes and how tissue heterogeneity contributes to function. These technologies have led to the development of programs, such as the NIH Human Biomolecular Atlas Program, to understand how cells interact in an organism to drive its function. The development of spatial transcriptomic technologies has allowed researchers to investigate how cell-cell interactions affect cellular gene expression within a tissue. Current approaches generally rely in situ RNA based methodolgies or slide-based sequencing in combination with scRNA-seq (e.g. Slide-seq) to generate spatial maps of interacting cells. These technologies have helped demonstrate the power of combining the tissues structural data with transcriptional data to better understand cell behavior in a tissue and going forward improving the interface between these technologies will be key to uncovering how structure and cell transcription drives function. However, multiple barriers impede the widespread adoption of the current methods for performing spatial transcriptomics, including significant financial cost, time requirements, and a lack of sufficient expertise. Herein, we propose to develop a simple reagent compatible with current protocols for drop-based and pipette-based scRNA-seq technologies. This reagent will be able to generate spatial data in the normal course of scRNA-seq experiments without significantly increasing cost or time commitments. We propose to invent “antibody-oligonucleotide bridges” and build software capable of bioinformatically generating a network of cell-cell contacts across the tissue to recapitulate the spatial relationships of the cells in a tissue. In this proposal, we will carry out a proof-of- principal experiment for the AO bridge scRNA-seq approach for generating the spatial relationships between cells.
项目摘要 单细胞RNA测序(scRNA-seq)使研究人员能够研究各种各样的基因。 生物学过程以及组织异质性如何促进功能。这些技术导致了 开发程序,如NIH人类生物分子图谱计划,以了解细胞如何 在有机体中相互作用以驱动其功能。空间转录组学技术的发展 使研究人员能够研究细胞间的相互作用如何影响组织内的细胞基因表达。 目前的方法通常依赖于基于原位RNA的方法学或基于载玻片的测序的组合 使用scRNA-seq(例如Slide-seq)来生成相互作用细胞的空间图。这些技术帮助 展示了将组织结构数据与转录数据相结合的能力, 细胞在组织中的行为,并继续改善这些技术之间的接口将是关键, 揭示了结构和细胞转录如何驱动功能。然而,多重障碍阻碍了 广泛采用目前的方法进行空间转录组学,包括显着 财务成本、时间要求和缺乏足够的专业知识。在此,我们建议开发一个简单的 试剂与当前的基于液滴和基于移液管的scRNA-seq技术的方案兼容。这 试剂将能够在scRNA-seq实验的正常过程中生成空间数据,而不需要 大大增加了成本或时间承诺。我们建议发明“抗体-寡核苷酸桥”, 构建能够以生物信息学方式生成整个组织中细胞间接触网络的软件, 概括组织中细胞的空间关系。在这份提案中,我们将进行一项证明- AO桥scRNA-seq方法的主要实验,用于生成 细胞
