Implementation Considerations

• Requires expertise in stem cell culture, extracellular matrix coating, and 3D tissue engineering techniques.
• Depends on access to laminin, porous polystyrene scaffolds, and controlled incubation environments (37°C, 5% CO₂).
• Necessitates cross-team standardization of medium change schedules and seeding densities for consistent outcomes.
• Involves adaptation considerations when transferring to alternative stem cell lines or disease-model backgrounds.
• Includes practical limitations such as scaffold porosity constraints and diffusion limits in thicker constructs over extended culture periods.
