摘要: The design of reliable biocompatible and biodegradable scaffolds remains one the most important challenges for tissue engineering. In fact, properly designed must display an adequate interconnected porosity to facilitate cell spreading colonization inner layers, release physical signals concurring modulate function ultimately drive fate. this study, a combination optimal mechanical biochemical properties has been considered one-component three-dimensional (3D) multitextured hydrogel scaffold favor cell–scaffold interactions. A polyethylene glycol diacrylate woodpile (PEGDa-Wp) structure order 100 μm manufactured using microstereolithography process. Subsequently, PEGDa-Wp embedded in PEGDa obtain 3D scaffold-in-scaffold (3D-SS) system. Finally, 3D-SS capability address fate assessed human Lin− Sca-1+ cardiac progenitor cells (hCPCs). Results have shown ...
