“…The ideal scaffold should have a uniform structure, excellent biocompatibility and biodegradability, as well as suitable mechanical strength, thus providing a specific environment for cell and tissue function in vitro and in vivo (Yang, Du, & Chua, ). So far, various types of materials such as biopolymer‐based hydrogels (Sá‐Lima, Caridade, Mano, & Reis, ) or nanofibers (Forget et al, ), synthetic polymer‐derived scaffolds (Izal et al, ) or hydrogels (Grant et al, ), and inorganic particle‐based nanocomposite hydrogels (Asadi et al, ) have been employed for cartilage regeneration. Particularly, synthetic, biodegradable polymers have been considered as useful scaffold materials, since their properties can be readily adjusted through the control of the polymerization reaction (Liu, Holzwarth, & Ma, ), but their biological efficiency as well as safety remain unsettled.…”
