简介：
Overview
This protocol describes the first apical-out necrotizing enterocolitis (NEC)-in-a-dish model utilizing small intestinal enteroids with reversed polarity. This method allows access to the apical surface of enteroids, enabling the testing of potential oral therapeutics.
Key Study Components
Area of Science
- Neuroscience
- Gastroenterology

- Further standardization may enhance model applicability.
What is necrotizing enterocolitis?
Necrotizing enterocolitis (NEC) is a serious intestinal disease primarily affecting premature infants.
How does the apical-out model differ from traditional models?
The apical-out model allows access to the apical surface of enteroids, improving the testing of oral therapeutics.
What methods are used to assess epithelial disruption?
An immunofluorescent staining protocol is employed to visualize epithelial integrity.
Can this model be used for different species?
Yes, but standardization may be required for tissue sourced from different ages and species.
What is the significance of this study?
It provides a novel in vitro system for studying intestinal inflammation and testing potential therapies.
What are the implications for oral therapeutics?
This model allows for the evaluation of how compounds are absorbed in a manner similar to in vivo conditions.
