“…Hyaluronic acid as a major role in tissue architecture, tissue regeneration, ingrowth of blood vessels, and cellular functions such as motility, adhesion, and proliferation (Jiang et al, 2011) has been utilized in DDS to improve long-acting and target-specific delivery (Tripodo et al, 2015;Highley et al, 2016;Jiao et al, 2016). In particular, due to the highly specific cellular receptor interaction and cellular uptake of hyaluronic acid in kidney, liver, lymphatic vessels, and tumor sites, hyaluronic acid often has been employed as carriers for intracellular drugs such as anti-tumor agents, and nucleic acids (Oh et al, 2010;Dosio et al, 2016;Lallana et al, 2017;Huang and Huang, 2018;Miyazaki et al, 2018).…”
