Assessing donor-to-donor variability in human intestinal organoid cultures

Area of Science:

• Gastroenterology
• Stem Cell Biology
• Organoid Technology

Background:

• Primary human organoid cultures, containing multiple cell types, present potential for donor-to-donor variability.
• This variability can introduce noise, complicating the interpretation of experimental results.

Purpose of the Study:

• To investigate and characterize donor-to-donor variability in human gut adult stem cell (ASC) organoids.
• To assess the consistency of intestinal developmental pathways and metabolic functions across different donors.

Main Methods:

• Established and cultured ileum- and colon-derived human gut ASC organoids from multiple donors.
• Examined intestinal developmental pathways during differentiation.
• Performed targeted analysis of central carbon metabolites.
• Analyzed hormone production patterns.

Main Results:

• Differentiation patterns were consistent across organoid cultures from various donors.
• Metabolic activity, including central carbon metabolism and hormone production, showed similar functions among donors.
• Observed metabolic activity reflected genuine intestinal biology.

Conclusions:

• Donor-to-donor variability in human gut ASC organoids is at a manageable level.
• ASC organoid cultures demonstrate consistent differentiation and metabolic functions, suitable for studying intestinal biology.
• This study provides a framework for generating high-confidence data from human primary organoid cultures by characterizing variability.
