3D Bioprinted organ. (A) 3D computer-aided design (CAD). (B,C) 3D bioprinted adult-sized ear constituted of fibroblast containing dermal bioink. As can be seen, the complex architecture was retained during culture (i.e., immersion in Dulbecco’s Modified Eagle Medium (DMEM) culture medium). (D) Mason’s Trichrome staining of human skin. (E) Mason’s Trichrome staining of Pourchet’s bioprinted skin construct. Image reproduced with permission from Pourchet et al. [127]. Copyright 2017 John Wiley & Sons.
