An example of adenoviral gene therapy in the human diabetic organ-cultured corneas is presented towards the normalization of delayed wound healing and markedly reduced epithelial stem cell marker expression in these corneas. It also describes the optimization of this process in stem cell-enriched limbal epithelial cultures.

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.

We present a protocol that combines cell isolation and whole-cell patch-clamp recording to measure the electrical properties of the primary dissociated epithelial cells from the rat cauda epididymides. This protocol allows for investigation of the functional properties of primary epididymal epithelial cells to further elucidate the physiological role of the epididymis.
FAQs
Epithelial cell markers provide evidence of identity by linking molecular signals to properties characteristic of epithelial tissue. Junction-associated components can indicate cell-cell organization, cytoskeletal proteins can reflect structural state, and lineage-associated surface molecules can add tissue-specific information. Examining these signals together helps distinguish epithelial cells from neighboring populations more reliably than interpreting one molecular feature alone.
These groups report different biological dimensions. Junction components relate to how epithelial cells connect, cytoskeletal proteins reflect structural organization, and lineage-associated surface molecules provide additional identity information tied to a cell population. Combining categories can therefore capture organization, internal architecture, and lineage context rather than treating all positive signals as interchangeable evidence.
Expression patterns are not fixed across biological contexts. Tissue type, developmental stage, and disease can each alter which molecular features are present or detectable. Consequently, a marker that supports epithelial identity in one setting may provide incomplete information in another. Interpreting expression alongside context helps prevent overly broad conclusions about cell identity or state.
A panel combines signals that represent different epithelial properties and lineage relationships. This reduces dependence on one feature whose expression may vary with tissue type, development, or disease. Concordant results across several markers provide stronger support for a cell classification, while mismatched signals can reveal heterogeneity or indicate that further characterization is needed.
Researchers can assess these markers through antibody binding, gene-expression analysis, or tissue staining. Antibody-based approaches detect the corresponding molecular feature, gene-expression analysis measures the related expression pattern, and staining shows marker distribution within tissue. Using these readouts allows investigators to connect molecular identity with cellular or tissue location when characterizing epithelial populations.
Marker panels help classify tumors by identifying epithelial-associated patterns and can also trace changes as cells undergo differentiation. Because expression may vary in disease or across developmental states, several signals are considered together rather than treating one marker as definitive. This approach supports comparisons between normal epithelial populations and altered or differentiating cells.
Cultured cells and organoid populations can be checked for epithelial identity by examining coordinated marker expression. Detecting appropriate junction, cytoskeletal, or lineage-associated signals helps verify that the population matches the intended epithelial character. This validation is useful because marker patterns can differ with tissue origin, developmental stage, or disease-related changes.
