Cellular viability depends on timely and efficient management of protein misfolding. Here we describe a method for visualizing the different potential fates of a misfolded protein: refolding, degradation, or sequestration in inclusions. We demonstrate the use of a folding sensor, Ubc9ts, for monitoring proteostasis and aggregation quality control in live cells using 4D microscopy.

Multi-modality imaging is a valuable approach for studying bacterial colonization in small animal models. This protocol outlines infection of mice with bioluminescent Citrobacter rodentium and the longitudinal monitoring of bacterial colonization using composite 3D diffuse light imaging tomography with μCT imaging to create a 4D movie of C. rodentium infection.
FAQs
Alignment places successive optical sections and time points into a consistent spatial framework. This allows researchers to compare the same cells, tissues, or structures as development proceeds rather than treating each image separately. Reliable alignment supports later segmentation and tracking, making observed movements and shape changes more interpretable across the complete volumetric time series.
Segmentation identifies cells or tissue regions within each volumetric dataset, while tracking connects those identified structures across successive time points. Together, these computational steps convert image sequences into measurements of division, migration, and shape change. Tracking can also reveal lineage relationships, which helps relate individual cellular behaviors to larger developmental events.
A three-dimensional snapshot shows structure at one moment, but adding time reveals how that structure changes. This temporal information can distinguish stable arrangements from active cell behaviors such as migration, division, or reshaping. In developmental biology, those dynamics help researchers connect cellular activity with tissue morphogenesis and construct quantitative models of embryonic development.
The workflow begins with time-lapse imaging that collects successive optical sections during development. These sections are combined into volumetric datasets and aligned across time. Researchers then apply computational segmentation and cell tracking to identify structures and follow them through the sequence. The resulting measurements describe changes in position, division, shape, and lineage over the observation period.
Analysis can reveal when and where cells divide, migrate, or change shape, as well as how those behaviors relate to lineage relationships. At the tissue level, the measurements show how cellular actions contribute to morphogenesis. These outcomes provide a quantitative basis for examining developmental organization rather than relying only on qualitative inspection of images.
Researchers can compare measured cellular behaviors and tissue changes with the expected developmental progression to identify abnormalities. Disruptions in division, migration, shape change, or lineage relationships may help explain altered tissue morphogenesis. Because the data preserve both spatial structure and temporal progression, they also support quantitative models that examine how cellular changes produce developmental defects.
