This study outlines quantitative measurements of synaptic size and localization, muscle morphology, and mitochondrial shape in C. elegans using freely available image processing tools. This approach allows future studies in C. elegans to quantitatively compare the extent of tissue and organelle structural changes as a result of genetic mutations.

Mapping Microglial Parameters Software (MMPS): An Open-Source, User-Friendly Tool for Quantitative Microglia Morphology Analysis
0 Views •
2026
Mapping Microglial Parameters Software (MMPS) is a user-friendly analysis pipeline that requires no coding expertise and semi-automates single-cell microglial morphology analysis from immunofluorescence images. Validated in a rodent lipopolysaccharide-induced neuroinflammation model, MMPS reproducibly detects activation-associated morphological changes and enables standardized, scalable microglial phenotyping.

Compound muscle action potential recording quantitatively assesses functional diaphragm innervation by phrenic motor neurons. Whole-mount diaphragm immunohistochemistry assesses morphological innervation at individual neuromuscular junctions. The goal of this protocol is to demonstrate how these two powerful methodologies can be used in various rodent models of spinal cord disease.

Bacterial and archaeal cells exhibit remarkable diversity in shape and structure, critical in their adaptability and functionality. Among bacteria, the most commonly observed shapes include cocci and bacilli. Cocci are spherical and may exist singly or in groupings such as pairs (diplococci), chains (streptococci), clusters (staphylococci), or tetrads. Bacilli, in contrast, are rod-shaped and can also occur as single cells, in pairs, or chains, depending on their environmental and genetic...
FAQs
Quantitative morphology makes visual differences analyzable by expressing features such as size, shape, and structural organization as numerical measurements. Those values can then be examined statistically under defined conditions, allowing investigators to compare patients, specimens, or experimental groups with greater consistency. The resulting analysis can expose subtle changes that may be difficult to judge reliably through visual inspection alone.
Image segmentation identifies the cells, tissues, or other structures to be measured within microscopy or medical imaging data. Computational descriptors then represent properties such as shape, size, or organization in a form suitable for numerical analysis. Together, these steps connect the original image with reproducible measurements and help organize structural observations for comparison across defined samples or conditions.
Defined conditions provide a consistent basis for collecting and comparing morphological measurements, while statistical analysis helps evaluate patterns across patients, specimens, or experimental groups. This combination reduces reliance on isolated visual impressions and supports objective assessment of structural variation. It is especially useful when the relevant difference is subtle and may not be apparent from qualitative examination alone.
Qualitative examination describes what appears different, whereas quantitative morphology adds numerical evidence about the magnitude and distribution of those differences. The two approaches can therefore provide complementary information: visual assessment preserves the observed structural context, while measurement supports reproducible comparisons. This combination strengthens investigations of pathological processes and helps evaluate whether morphological changes are associated with disease or treatment.
A typical workflow starts with microscopy or medical imaging collected under defined conditions. Relevant structures are then identified through image segmentation, followed by extraction of computational descriptors for features such as size, shape, or organization. Statistical analysis of those measurements allows comparisons among patients, specimens, or experimental groups and produces numerical evidence for interpreting morphological differences.
Researchers may apply quantitative morphology when they need objective comparisons of cell, tissue, or organ structure. Medical uses described for the approach include diagnostic research, biomarker development, evaluation of pathological processes, and assessment of treatment response. Measurements can also help investigate disease progression by revealing structural changes across patients, specimens, or experimental groups.
