Cell-to-cell context
Identify the populations, boundaries, distances and signals that may influence differentiation or development.
Application pathway: stem cell models
Pattern cells and materials with biological intent.
Stem cell and developmental models can depend on neighbouring populations, matrix context, gradients and change over time. JetBio starts with those interactions, then assesses the deposition route and workflow.
Model design
Define the interaction the experiment needs.
Spatial organisation is useful only when it supports a biological hypothesis. A development brief should explain which cells and materials must be positioned, what changes over time and how those changes will be measured.
Cell-to-material context
Define the hydrogel, substrate, structural support and crosslinking conditions required by the cells.
Maturation and change
Set sampling points and readouts for morphology, identity, organisation or function over time.
Modular process development
Match deposition to the cells and material system.
ReJI, microvalve and inkjet development modes provide different ways to form gels and place droplets or patterns. The best route depends on the intended structure, material behaviour, cell sensitivity, culture workflow and readout.
- Defined cell populations and starting state
- Material composition and crosslinking route
- Spatial relationship and feature scale
- Culture, differentiation and maturation protocol
- Imaging, sampling and identity markers
Feasibility questions
Connect the print to the biological readout.
Which developmental event matters?
Define the differentiation, self-organisation, migration or maturation process under study.
Which starting state must be controlled?
Record cell source, identity, passage, preparation, density and relevant quality measures.
Which structure is necessary?
Separate essential placement or geometry from complexity that does not change the experiment.
How will variability be assessed?
Plan controls, replicate numbers, time points and measures of biological and process consistency.
Research context
Application learning in active research settings.
The Cambridge Stem Cell Institute describes a MiniREJI research system funded through the NC3Rs 3D-IV programme. Newcastle University also hosts a ReJI dataset involving intestinal stem cells derived from pre-term infant gut organoids. These are research-use signals, not commercial or clinical validation.
