项目摘要

SBIR Abstract Single cell biology is a multi-disciplinary study to investigate how large amount of molecular species interact with each other in single cells and how large population of cells work together as a complex system. Identifying the difference of gene expression and the spatial organization of tissues at the single-cell level is essential to decipher tissue heterogeneity, organ development, and understand the biological systems profoundly, and ultimately benefit precision and personalized medicine. Currently, single cell RNA sequencing is widely used to analyze the gene expression patterns of single cells. However, single cell RNA sequencing has significant limitations, including lack of spatial information, low RNA detection efficiency and low cell capture efficiency. Existing multiplexed in-situ detection technologies like MERFISH and seqFISH can overcome these limitations but has long turnaround time. UltraFISH, developed by Rainbow Diagnostics, significantly improves the turnaround time for a small panel of RNA detection in-situ. High Capacity UltraFISH is to further advance the multiplex capacity of UltraFISH so that a large RNA panel such as the whole human transcriptome from a large region of tissue can be efficiently and quickly profiled in hours. With the successful outcome of this proposal, High Capacity UltraFISH will revolutionize the single cell analysis field, leading to breakthroughs in our understanding of biological and disease mechanisms in the near future.

SBIR摘要单细胞生物学是一项多学科研究，旨在研究有多少细胞分子种类在单细胞中相互作用以及大量细胞如何工作一起作为一个复杂的系统。识别基因表达和空间的差异单细胞水平的组织组织对于破译组织异质性至关重要，器官发育，深刻理解生物系统，最终受益精准和个性化医疗。目前，单细胞RNA测序被广泛应用于分析单细胞的基因表达模式。然而，单细胞 RNA 测序显着的局限性，包括缺乏空间信息、RNA 检测效率低和低细胞捕获效率。现有的多重原位检测技术，如 MERFISH 和 seqFISH 可以克服这些限制，但周转时间较长。 UltraFISH，开发者 Rainbow Diagnostics 显着缩短了一小批 RNA 的周转时间原位检测。高容量UltraFISH是为了进一步提高多重能力 UltraFISH 使大型 RNA 组（例如来自大型 RNA 组的整个人类转录组）可以在数小时内有效、快速地分析组织区域的轮廓。随着成功的结果这一提议，高容量 UltraFISH 将彻底改变单细胞分析领域，从而导致在不久的将来，我们对生物和疾病机制的理解将取得突破。
