microbial transglutaminase (mTG) is used as a crosslinking agent in the preparation of gelatin sponges. The physical properties of the materials are evaluated by measuring their material porosity, water absorption, and elastic modulus. The stability of the sponges are assessed via hydrolysis and enzymolysis, overview. To evaluate the cell compatibility of them TG crosslinked gelatin sponges (mTG sponges), adipose-derived stromal stem cells are cultured and inoculated into the scaffold. Cell proliferation and viability are measured using alamarBlue assay and LIVE/DEAD fluorescence staining, respectively. Cell adhesion on the sponges is observed by scanning electron microscopy. mTG sponges have uniform pore size, high porosity and water absorption, and good mechanical properties. In subcutaneous implantation (in Sprague-Dawley rats), the material is partially degraded in the first month and completely absorbed in the third month. Cell experiments show evident cell proliferation and high viability. The cells grow vigorously and adhered tightly to the sponge. In conclusion, mTG sponge has good biocompatibility and can be used in tissue engineering and regenerative medicine

Celiac disease is mediated by IgA antibodies to wheat gliadins and tissue transglutaminase (tTG). As tTG is homologous to microbial transglutaminase (mTG) used to improve foodstuff quality, it could elicit the immune response of celiac patients. Sera pool IgA titers are higher against prolamins of mTG-treated wheat or gluten-free breads than against mTG-untreated, mainly due to two individual patients sera. The electrophoretic pattern of gluten-free bread prolamins is changed by the mTG treatment, and a new 31000 band originates in maize is recognized by three CD patients IgA. It is suggested that IgA immunoreactivity can be used as a preliminary test of the safeness of a food product for celiac disease patients

MTGase treatment significantly increases the denaturation temperature of beta-lactoglobulin in whey protein isolate, from 71.84°C in the untreated sample to 78.50°C after 30 h of incubation with MTGase. Increase in ´denaturation temperature is primarily due to covalent cross-linking and not due to an increase in nonpolar interactions within the protein. The surface hydrophobicity of the protein decreases upon cross-linking, due to occlusion of the hydrophobic cavities to the fluorescent probes. The cross-linked protein exhibits a U-shaped pH-stability profile with maximumturbidity at pH 4.0-4.5
