Abstract
A key goal in the bioengineering field is the development of surface patterning of proteins that guide and control cellular organization. To this end, we developed a method to create a microstructured hydrogel based on soft-lithography techniques using polydimethylsiloxane (PDMS) and polyethylene glycol diacrylate (PEGDA). This approach involves the design of microfluidic geometries using graphical software, employing PDMS as a mold and leaving PEGDA as a substrate for the fabrication of microstructures and, thus, patterning extracellular matrix (ECM) proteins to promote cell adhesion. The combination of these techniques allows the fabrication of hydrogel microstructures without following conventional photolithography methods, such as the use of a photomask, the alignment required to produce the patterns, and the associated expenses. This study highlights the versatility and potential of PEGDA-based hydrogels as platforms to advance tissue engineering strategies. Key features • This protocol focuses on investigating the feasibility of patterning PEGDA as a substrate for protein surface patterning and further tissue engineering applications. • Optimization of the fabrication of PEGDA hydrogels into simple shapes and angular patterns, ensuring a robust substrate capable of guiding cellular responses.
