Barrier and delivery question
Define tissue interface, candidate format and whether the question is transport, retention, injury or repair.
Application
Organoid delivery and barrier studies
Confirm barrier structure and baseline function, then interpret candidate transport or retention alongside barrier-integrity readouts.
Barrier structure and permeability
Evaluate permeability in the context of barrier integrity
Mouse intestinal organoid evidence combines FITC-Dextran permeability, F-actin/ZO-1 and tissue-function readouts to characterize epithelial barrier state. Human inflammatory bowel disease and blood–brain barrier studies can then be tailored to the available samples, cell system and required functional endpoints.

Study focus
What this study can help you decide
- 01What functional baseline does the barrier model achieve?
- 02How can candidate transport or retention be quantified reliably?
- 03How does permeability change relate to barrier injury?
Study workflow
How the study moves from question to results
Baseline and batch QC
Confirm cell identity, tight junctions, baseline permeability and acceptance criteria.
Exposure and permeability
Define orientation, time, concentration, recovery and controls with appropriate tracing or quantification.
Transport and barrier integrity
Interpret permeability with viability, morphology and junction markers to build an integrated view of transport, retention and barrier status.
Model options
Match the model to indication, mechanism and sample
Intestinal organoids support barrier-function and inflammation studies, while blood–brain barrier programs use co-development to configure the cell system and functional endpoints. Permeability can be interpreted with recovery, mass balance and barrier integrity to guide follow-on in vivo work.
PROJECT DISCUSSION
Plan a delivery or barrier study
Tell us about the candidate or formulation, the target barrier and the exposure direction. We’ll recommend the model and the permeability and barrier-integrity readouts needed to assess transport, retention or barrier effects.
