Abstract
The human intestine plays a pivotal role in nutrient absorption and immune system regulation. Along the longitudinal axis, cell-type composition changes to meet the varying functional requirements. Therefore, our protocol focuses on the processing of the whole human intestine to facilitate the analysis of region-specific characteristics such as tissue architecture and changes in cell populations. We describe how to generate a biobank that can be used to isolate specific immune cell subtypes, generate organoid lines, and establish autologous immune cell-organoid co-cultures.
Key features
• Dissection and tissue analysis of whole human intestines.
• Cryopreservation for biobank generation.
• Optimized protocols for the isolation of epithelial and immune cells.
• Autologous co-culture of organoids and lamina propria–derived immune cells.

Background
The intestine is the longest organ of the human body and possesses the largest surface area, being also constantly exposed to commensal and pathogenic bacteria. Thus, maintaining barrier integrity and accurate immune surveillance is crucial to preserve its function and homeostasis. A dysfunction in the epithelial barrier or in the immune cell composition of the intestine can lead to severe and chronic diseases, from cancer to autoimmune diseases. Therefore, it is essential to understand the interaction between the epithelial barrier and the immune cells as well as to identify region-specific immune cell subpopulations.
Access to intestinal tissue is limited, and most research relies on small biopsies (<5 cm) or intestinal resections (<40 cm long) [1–3]. However, to fully understand the complexity and regional variations, studying the intestine in its entirety is necessary. Additionally, this allows the analysis of the jejunum and ileum, which are particularly difficult to address with biopsies or resections.
Processing such a large organ requires a stringent protocol that focuses on the cryopreservation and time-independent analysis of the samples. Moreover, the focus of most cryopreservation methods is on the recovery of a specific cell population [4,5], but they do not address the isolation of cells from different intestinal regions or simultaneous epithelial and immune cell isolation [3,6].
Our protocol closes this gap by describing a cryopreservation method that supports the preservation of both immune and epithelial cells of various intestinal regions while additionally being applicable to cell isolations from fresh tissue. It serves as an essential and versatile guideline for the preservation and cell isolation of the whole human intestine while providing additional options for tissue analysis.
We give a detailed description of an optimized and refined protocol that describes how to process the whole intestine, generate a biobank, and perform cell isolation from fresh and cryopreserved tissue. In particular, techniques for the generation of intestinal organoids and the isolation of epithelium and immune cells with enrichment of specific cell fractions depending on the enzyme digestion carried out are presented. Finally, we provide a protocol to establish an autologous immune cell-organoid co-culture, which can be further modified to study one specific intestinal region or immune cell subtype.
