|Abstract(s):||[Excerpt] On the road to successfully achieving skin regeneration, 3D matrices/scaffolds that provide the adequate physico-chemical and biological cues to recreate the ideal healing environment are believed to be a key element ,  and . Numerous polymeric matrices derived from both natural  and  and synthetic ,  and  sources have been used as cellular supports; nowadays, fewer matrices are simple carriers, and more and more are ECM analogues that can actively participate in the healing process. Therefore, the attractive characteristics of hydrogels, such as high water content, tunable elasticity and facilitated mass transportation, have made them excellent materials to mimic cells’ native environment . Moreover, their hygroscopic nature  and possibility of attaining soft tissues-like mechanical properties mean they have potential for exploitation as wound healing promoters , ,  and . Nonetheless, hydrogels lack natural cell adhesion sites , which limits the maximization of their potential in the recreation of the cell niche. This issue has been tackled through the use of a range of sophisticated approaches to decorate the hydrogels with adhesion sequences such as arginine-glycine-aspartic acid (RGD) derived from fibronectin ,  and , and tyrosine-isoleucine-glycine-serine-arginine (YIGSR) derived from laminin  and , which not only aim to modulate cell adhesion, but also influencing cell fate and survival . Nonetheless, its widespread use is still limited by significant costs associated with the use of recombinant bioactive molecules.|
