WebHerein, we propose a composite hydrogel that encapsulates gelatin methacryloyl (GelMA)/chitosan microspheres (GCMSs) as ARPE-19 cell transplantation carriers. The diameter of the GCMS was adjusted by tuning the parameters of the microfluidic devices, yielding a cell-adhering platform that induced uniform cell spreading. WebWe developed a physiological microenvironment of semisynthetic origin, called gelatin methacryloyl (GelMA)-based hydrogels, which combine the biocompatibility of natural matrices with the reproducibility, stability and modularity of synthetic biomaterials.
