Extracellular Matrix Engineering for Cell Behavior Modulation

Extracellular matrix engineering harnesses the structural and biochemical complexity of the native cellular microenvironment to direct cell adhesion, migration, proliferation and differentiation. By tuning parameters such as matrix stiffness, topography, ligand density and degradability, researchers can mimic dynamic processes of tissue development and repair. Synthetic polymers, protein‐based scaffolds and hybrid biointerfaces are functionalised with adhesive motifs, growth factor binding domains or enzymatically cleavable linkages to establish precise spatiotemporal control over cell–matrix interactions. Advances in three‐dimensional hydrogel design, stimuli-responsive materials and living interfaces permit reversible modulation of mechanical cues and biochemical presentation, opening routes to regenerative therapies, disease modelling and high-throughput screening platforms. Integrating insights from mechanotransduction, growth factor signalling and matrix remodelling has transformed our capacity to engineer the extracellular matrix as a dynamic regulator of cell behaviour.

Recent studies have combined epigenetic modulation with matrix mechanics to enhance lineage reprogramming. By applying DNA methylation inhibitors alongside three-dimensional gelatin matrices of tunable rigidity, investigators achieved efficient transdifferentiation of adipose-derived stromal cells into myoblast-like cells, demonstrating that the interplay between chemical cues and substrate stiffness can govern cell plasticity and tissue regeneration.

Another innovative approach has employed non-pathogenic bacterial biofilms engineered to express fibronectin fragments on their surface. These living interfaces support long-term mesenchymal stem cell culture, sustain focal adhesion formation and, with the addition of osteogenic growth factors, promote robust osteoblastic differentiation. This platform illustrates how cell–material interfaces can be endowed with self-renewing biological functionality.

Fine-tuning of polymer surface mobility through acrylate copolymer composition has revealed a direct correlation between fibronectin nanonetwork organisation, focal adhesion dynamics and myoblast differentiation. Systematic variation of side-chain length in poly(ethyl acrylate-co-butyl acrylate) substrates modulates extracellular matrix mobility, altering integrin engagement and downstream lineage commitment.

Complex hydrogels integrating full-length fibronectin covalently crosslinked to hyaluronic acid have enabled independent control of matrix mechanics and biochemical presentation. In two-dimensional cultures, increased fibronectin content drives nuclear translocation of mechanosensitive regulators, whereas three-dimensional encapsulation reveals distinct dependencies of stem cell fate on matrix architecture.

Materials combining covalently tethered growth factors with integrin-binding motifs have illustrated synergistic signalling effects. By recapitulating solid-state growth factor presentation alongside precisely patterned adhesion ligands, these engineered microenvironments enhance stem cell differentiation and vascular network formation at lower cytokine doses than soluble administration, highlighting the cooperative interplay between mechanotransduction and biochemical cues.
