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.

Begin with a rat model with sutures tied around its upper molar teeth to support bacterial colonization.Repeatedly smear the sutures with a gum disease-causing oral pathogenic bacterium using a gel-like solution.The bacteria colonize the gum around the sutures.Colonization triggers inflammation and damages the tissues.The bacteria release toxins that diffuse through damaged tissues and enter the bloodstream.These circulating toxins reach the gut, cause inflammation, disrupt the epithelial...

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.

neuroHuMiX is an advanced gut-on-a-chip model to study the interactions of bacterial, epithelial, and neuronal cells under proximal and representative co-culture conditions. This model allows unravelling of the molecular mechanisms underlying the communication between the gut microbiome and the nervous system.
FAQs
Epithelial polarity creates distinct tissue-facing and lumen-facing organization while preserving selective permeability across the intestinal surface. This arrangement allows researchers to examine how tumor-associated changes affect barrier function and interactions with neighboring tissue. Maintaining that organized architecture is therefore important when investigating tumor initiation, invasion, or barrier disruption in a controlled experimental setting.
Mucus-producing cells contribute the protective mucus layer, while stromal and immune components help represent the surrounding local microenvironment. Their inclusion provides more than an epithelial surface alone: it enables investigation of interactions between intestinal tumor processes and nearby supporting or responding cells. This broader cellular context is particularly relevant to studying inflammation and tumor–tissue interactions.
These models can complement animal studies by offering a controlled platform for examining human-relevant interactions between tumors and intestinal tissue. Researchers can investigate specific processes within the mucosal environment without treating the model as a complete substitute for an organism. This complementary role supports focused analysis of disease mechanisms and therapeutic strategies before or alongside animal research.
Construction begins by organizing intestinal epithelial cells into a polarized, selectively permeable surface. Mucus-producing cells can help recreate the mucus layer, and stromal or immune components can be incorporated to represent surrounding tissue interactions. The resulting arrangement is then used as an experimental setting for studying gastrointestinal biology, disease processes, and cancer-related changes within the mucosal environment.
A mucosal system can support controlled investigation of tumor initiation, invasion, barrier disruption, and inflammation. These processes can be examined in relation to the epithelial surface, mucus layer, and surrounding cellular environment rather than in isolation. In cancer research, that organization helps connect changes in tumor behavior with effects on intestinal tissue and local microenvironmental interactions.
Researchers can use these platforms to analyze responses to anticancer treatments in an organized intestinal tissue context. Because the model includes the epithelial barrier and may include mucus-producing, stromal, or immune components, treatment studies can consider effects on tumor–tissue interactions and barrier-associated changes. This makes the system useful for evaluating therapeutic strategies alongside other experimental approaches.
