We present here a cell culture method for inducing mesenchymal-epithelial transitions (MET) in sarcoma cells based on combined ectopic expression of microRNA-200 family members and grainyhead-like 2 (GRHL2). This method is suitable for better understanding the biological impact of phenotypic plasticity on cancer aggressiveness and treatments.

Ring-Shaped Micropatterning Cell Chirality Assay: An In Vitro Technique to Determine Multicellular Chirality Based on Cell Alignment on Ring-Shaped Micropatterns

2025
In this video, we describe a cell chirality assay to determine the alignment bias of cells in a confined geometric boundary such as a ring micropattern. Chirality is an inherent property of most cell types and is determined by genetic and environmental factors. Knowing the chirality of a normal cell population can help to screen drug-treated cells.
FAQs
Cell height-to-width ratio is a visible outcome of underlying cytoskeletal organization, junctional contacts, and polarity cues. The cytoskeleton helps establish cell geometry, junctions connect neighboring cells, and polarity cues orient cells within the lining. Together, these features link individual shape to tissue architecture, helping explain how epithelial arrangements support barrier, transport, or glandular roles.
Squamous, cuboidal, and columnar arrangements are associated with different epithelial geometries, so the height-to-width relationship provides structural clues about tissue behavior. Within a tissue, shape and organization influence permeability, transport, and barrier strength rather than serving as labels alone. Examining these features can therefore connect morphology with the functional demands of a lining.
Mechanical forces and polarity cues can alter tissue architecture, allowing epithelial arrangements to change during development or wound repair. The same remodeling principle helps interpret abnormal patterns linked with inflammation, fibrosis, and cancer. Thus, shape should be considered dynamic rather than fixed, especially when microscopy reveals departures from the expected organization of a tissue lining.
Microscopy enables investigators to inspect cell geometry and organization within a tissue lining. They can evaluate whether cells appear squamous, cuboidal, or columnar by considering relative height and width, then relate that pattern to surrounding junctional contacts and overall architecture. This approach supports tissue classification and provides a visual basis for studying changes during development or repair.
Epithelial cell shape is especially informative when researchers need to classify a lining, compare tissue architecture, or interpret how a tissue is changing. Microscopy-based assessment can contribute to studies of development and wound repair, while deviations from usual organization may provide context for inflammation, fibrosis, or cancer. The value lies in connecting visible morphology with tissue state and function.
Interpretation depends on the tissue role being examined. A lining may be assessed in relation to protection, absorption, secretion, permeability, transport, or barrier strength, rather than by shape in isolation. This functional context helps prevent overinterpreting a squamous, cuboidal, or columnar appearance and supports comparisons of epithelial organization across organs.
