We demonstrate methods for the detection of architectural distortion in prior mammograms. Oriented structures are analyzed using Gabor filters and phase portraits to detect sites of radiating tissue patterns. Each site is characterized and classified using measures to represent spiculating patterns. The methods should assist in the detection of breast cancer.

This protocol is designed for the imaging and analysis of the dynamics of cell orientation and tissue growth in the Drosophila abdominal epithelia as the fruit fly undergoes metamorphosis. The methodology described here can be applied to the study of different developmental stages, tissues, and subcellular structures in Drosophila or other model organisms.

Oriented Surfaces

2026
A surface is called orientable if a consistent choice of unit normal vector can be made at every point on the surface. A thin soap film stretched across a wire loop provides a familiar example. The film separates the air on one side from the air on the other, so one side can be selected as positive and the opposite side as negative. Once this choice is made, a unit normal vector can be assigned smoothly across the entire surface.At each point on the soap film, a unit normal vector points...

Location and Orientation of the Heart

2024
The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.
FAQs
Polarity markers help distinguish how cells are oriented relative to anatomical axes rather than simply showing where cells are located. When combined with microscopy, they allow researchers to identify directional organization and relate it to coordinated cell division, migration, elongation, or remodeling. This makes it possible to connect cellular alignment with larger changes in developing organs and embryos.
Anatomical axes provide the reference framework for determining whether cells or tissue structures align in a coordinated direction. Without that reference, an apparent pattern may be difficult to compare between regions or developmental stages. Relating measurements to axes therefore helps reveal organized patterning and shows how local cellular behavior contributes to tissue shape and function.
Changes in orientation can indicate that tissue patterning or morphogenesis has been altered. For example, differences in alignment may be associated with disrupted coordination of cell division, migration, elongation, or tissue remodeling. Comparing these patterns across experimental conditions helps researchers connect an observable structural change with the cellular behaviors that shape organs and embryos.
A typical workflow begins with microscopy to visualize cells, fibers, or other tissue structures. Researchers then use molecular or anatomical markers to identify polarity and establish relevant anatomical regions or axes. Orientation or alignment is measured, followed by comparisons across developmental time, tissue regions, or experimental conditions. The resulting data support interpretation of patterning and morphogenesis.
Researchers can collect orientation measurements from selected developmental stages or distinct tissue regions and evaluate how alignment changes between them. The same comparison can be made between experimental conditions to identify altered organization. These analyses show whether orientation is maintained, reorganized, or disrupted over time, providing quantitative evidence about tissue remodeling and developmental patterning.
In developmental biology, orientation data help explain how coordinated cellular behaviors produce organ and embryo form. The approach can also support investigations of disrupted patterning linked to congenital defects, as well as studies of regeneration and tissue engineering. By connecting structural organization with developmental outcomes, it provides a way to evaluate how tissues form, change, or recover.
