Label-free Brain Organoid Imaging with Fourier Ptychographic Microscopy

Published:Dec 30, 2025 22:17
1 min read
ArXiv

Analysis

This paper introduces a novel application of Fourier ptychographic microscopy (FPM) for label-free, high-resolution imaging of human brain organoid slices. It demonstrates the potential of FPM as a cost-effective alternative to fluorescence microscopy, providing quantitative phase imaging and enabling the identification of cell-type-specific biophysical signatures within the organoids. The study's significance lies in its ability to offer a non-invasive and high-throughput method for studying brain organoid development and disease modeling.
Reference

“Nuclei located in neurogenic regions consistently exhibited significantly higher phase values (optical path difference) compared to nuclei elsewhere, suggesting cell-type-specific biophysical signatures.”

Quantitative Light-Sheet Microscope for Subcellular Dynamics

Published:Dec 29, 2025 15:50
1 min read
ArXiv

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.
Reference

“The system combines high numerical aperture remote refocusing with tilt-invariant light-sheet scanning and hardware-timed synchronization of laser excitation, galvo scanning, and camera readout.”

Morphology-Preserving Holotomography for 3D Organoid Analysis

Published:Dec 27, 2025 06:07
1 min read
ArXiv

Analysis

This paper presents a novel method, Morphology-Preserving Holotomography (MP-HT), to improve the quantitative analysis of 3D organoid dynamics using label-free imaging. The key innovation is a spatial filtering strategy that mitigates the missing-cone artifact, a common problem in holotomography. This allows for more accurate segmentation and quantification of organoid properties like dry-mass density, leading to a better understanding of organoid behavior during processes like expansion, collapse, and fusion. The work addresses a significant limitation in organoid research by providing a more reliable and reproducible method for analyzing their 3D dynamics.
Reference

“The results demonstrate consistent segmentation across diverse geometries and reveal coordinated epithelial-lumen remodeling, breakdown of morphometric homeostasis during collapse, and transient biophysical fluctuations during fusion.”
