Project description:- Background: Optimized diets during the first period of life may be most effective for improving gut and overall health. Here, we set up an interdisciplinary research pipeline to evaluate gut health benefits of early life nutrition ingredients through advanced integration of in vitro and modeling technologies that represent the infant gut environment. - Methods: In our InTESTine platform (TM), biopts of piglet gut tissue (Jejunum or Colon) were exposed (0-6h) to various infant/piglet-formula-milk based food matrices (-/+ prebiotics; -/+ predigestion by infant/piglet fecal microbiome). RNA expression of the piglet gut tissue biopts was measured by RNAseq. - Results: To be published in various papers. - Conclusion: To be published in various papers.
