Implementation Considerations

• Requires expertise in cell dissociation, hydrogel chemistry, and 3D culture techniques.
• Depends on access to silicone molds, hydrogel precursors (PEG-Mal, peptides), and hyaluronic acid solutions.
• Necessitates standardized mixing and incubation protocols to ensure rapid, uniform gelation.
• Involves adaptation considerations for different cell densities and glioma sphere sources.
• Limited by the need for precise timing due to rapid hydrogel formation after component mixing.
