Questions & Answers

Q: What is the murphish technology and how does it work?

Murphish, short for multiplexed air robust fluorescence in situ hybridization, is a spatial transcriptomics technology that allows researchers to analyze gene expression in tissues directly, without needing to extract RNA. It employs a binary encoding scheme to tag genes, enabling simultaneous measurement of hundreds of them across large tissue areas. The technology provides a spatial map of gene expression, illustrating how cells interact within their environment.

Q: Why is spatial organization of cells important in biology?

Understanding the spatial organization of cells is crucial because it reveals how tissues function as integrated units rather than isolated cells. Cells communicate and interact with their surroundings, which can influence their behavior. In both healthy and diseased tissues, spatial organization plays a significant role in cellular function and pathology, helping researchers identify mechanisms underlying diseases like cancer.

Q: What differentiates murphish from traditional transcriptomics techniques?

Unlike traditional transcriptomics methods that often analyze RNA extracts and lose spatial context, murphish retains the spatial arrangement of cells. This allows for higher detection efficiency and quantitative analysis directly within tissue samples. Traditional methods may miss significant information about interactions and cellular environments that are pivotal for understanding biological systems.

Q: What are some applications of murphish technology in research?

Murphish technology has been applied in various research fields, such as neuroscience, to map different types of neurons in the brain. In oncology, it helps assess tumor microenvironments and interactions between cancer cells and immune cells. Its ability to measure numerous genes simultaneously enhances our understanding of complex biological questions across diverse specimen types.
