Quantitative Light-Sheet Microscope for Subcellular Dynamics
Analysis
This paper presents a significant advancement in light-sheet microscopy, specifically focusing on the development of a fully integrated and quantitatively characterized single-objective light-sheet microscope (OPM) for live-cell imaging. The key contribution lies in the system's ability to provide reproducible quantitative measurements of subcellular processes, addressing limitations in existing OPM implementations. The authors emphasize the importance of optical calibration, timing precision, and end-to-end integration for reliable quantitative imaging. The platform's application to transcription imaging in various biological contexts (embryos, stem cells, and organoids) demonstrates its versatility and potential for advancing our understanding of complex biological systems.
