종설 : 조직 및 장기 재생 분야에서의 3D 프린팅 기술의 적용 현황

Three-dimensional (3D) printing, also known as additive manufacturing (AM), has been used frequently in regenerative or translational medicine. In addition, recent advances in 3D printing technologies have opened the door to 3D bio-printing, which uses cells, biocompatible materials, and scaffolding simultaneously to generate 3D functional tissues. Although tissue generation by bio-printing such as multilayered skin, bone, bladder, and vascular grafts has shown good results, there are still several challenges related to printing of entire organs, particularly modulation of vascular formation during organ regeneration. This article provides a background and introduction to bio-printing for creation of artificial organs and tissues.
