Schematic representation from the synthesis of the bioink to the characterization of the 3D printed patches. (A) Reaction scheme between HMwHAs and Me to produce MeHA. (B)1 H NMR spectra of MeHA. (C) 3D printing of MeHA. (D) From left to right: G-code, printing process by using UV light and picture of 3D printed patch, respectively. (E) SEM images of 3D printed patch. Scale Bar: 2 mm (left) and 500 μm (right). (F) Results obtained from DMA tests performed on 3D printed patches. (G) Swelling behavior of MeHA patches up to 5 h. (H) MSC-sEVs release from MeHA patches from 30 min to 11 days
