Polystyrene-based 3D cell culture scaffolds are established tools for in vitro models designed to improve physiological relevance by enabling three-dimensional cell growth in a controlled, highly porous polymer architecture. Compared with conventional 2D cell culture surfaces, these systems support enhanced cell–cell and cell–ECM interactions, improved maintenance of native cell morphology, and more tissue-relevant organization, making them valuable for advanced cell biology, cancer research, stem cell studies, and drug discovery workflows.
Alvetex® technology is a widely used platform for routine and advanced 3D cell culture applications, based on engineered polystyrene scaffold systems designed to support reproducible 3D cell growth.
Alvetex Scaffold
Alvetex Scaffold is a highly porous, cross-linked polystyrene membrane (approximately 200 µm thick) that enables dissociated mammalian cells to infiltrate and proliferate within a 3D porous structure. Its interconnected pore network facilitates diffusion of oxygen and nutrients throughout the culture, supporting the formation of tissue-like cell assemblies. Cells cultured within Alvetex Scaffold commonly exhibit improved viability and more physiologically relevant morphology compared with standard 2D monolayer cultures, depending on cell type and experimental conditions.
Alvetex Strata
Alvetex Strata is a complementary polystyrene membrane designed primarily for surface-based 3D culture, allowing cells or tissue explants to grow and be maintained on a highly porous support rather than within the scaffold. This configuration supports long-term culture, co-culture systems, and organotypic tissue models while maintaining access to standard imaging and analytical workflows.
Nanofiber Scaffolds
Nanofiber Scaffolds are ECM-mimetic fibrous networks composed of nanoscale fibers engineered to replicate aspects of native extracellular matrix architecture. They offer high surface area, tunable porosity, and flexible biofunctionalization with adhesion molecules or ECM proteins, enabling controlled regulation of cell adhesion, migration, and differentiation in 3D culture systems used in tissue engineering and regenerative medicine.
