A mouse model of human endoscopic skull base reconstruction has been developed that creates a semipermeable interface between the brain and nose using nasal mucosal grafts. This method allows researchers to study delivery to the central nervous system of high molecular weight therapeutics which are otherwise excluded by the blood-brain barrier when administered systemically.

Mucosal Barrier of the Stomach

The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl. Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

This manuscript describes the production, characterization and potential uses of a tissue engineered 3D esophageal construct prepared from normal primary human esophageal fibroblast and squamous epithelial cells seeded within a de-cellularized porcine scaffold. The results demonstrate the formation of a mature stratified epithelium similar to the normal human esophagus.

Separation of Mixtures via Precipitation

Source: Laboratory of Dr. Ana J. García-Sáez — University of Tübingen Most samples of interest are mixtures of many different components. Sample preparation, a key step in the analytical process, removes interferences that may affect the analysis. As such, developing separation techniques is an important endeavor not just in academia, but also in industry. One way to separate mixtures is to use their solubility properties. In this short paper, we will deal with aqueous solutions. The...

Its main analytical value comes from reducing the masking effect of deeper wall layers. By examining the mucosa separately, researchers can attribute morphological, gene-expression, protein, or cellular changes more specifically to epithelial and stromal compartments. Comparisons with submucosa, muscle, or normal controls can then distinguish mucosa-associated alterations from signals originating elsewhere in the tissue.
The mucosa contains epithelial and stromal components that may undergo different cancer-related changes. Maintaining this layer separately allows investigators to evaluate those compartments without automatically combining their signals with underlying submucosa or muscle. This distinction supports more focused assessment of local tumor interactions and helps clarify whether an observed molecular or cellular pattern is compartment-specific.
Full-thickness analysis combines mucosal, submucosal, and muscular material, which can make it difficult to assign findings to a particular layer. Mucosal Separation instead enables direct comparison between the mucosa and adjacent structures. That comparison can reveal whether differences in morphology, gene expression, proteins, or cellular composition are concentrated in the mucosal compartment or distributed across the wall.
A typical workflow begins by identifying the mucosal layer and carefully separating it from the underlying submucosa and muscle. Researchers may use mechanical dissection or layer-specific processing, while taking care to preserve the collected material. The isolated mucosa can then be directed to morphology, gene-expression, protein, or cellular analyses, with adjacent layers retained when comparisons are needed.
The separated material can support several complementary readouts, including tissue morphology, gene expression, protein measurements, and cellular changes. Using more than one readout helps connect structural findings with molecular or cellular patterns within the mucosa. Researchers may also compare these results with adjacent tissue layers or normal controls to strengthen interpretation of cancer-associated differences.
It is especially useful when investigators need to understand how tumors arise within mucosa-associated tissues, interact with their local microenvironment, or respond to treatment. Separating the mucosa helps focus measurements on relevant epithelial and stromal compartments while preserving the option to compare deeper layers. The resulting data can support more precise investigation of gastrointestinal and other mucosa-associated cancers.
