Organoids cover a wide range of three-dimensional multicellular in vitro human tissue constructs that are used to mimic its corresponding in vivo organ in research.
The word ‘organoid’ is relatively new and most commonly describes constructs derived from stem cells – either pluripotent or adult stem cells – from various organs. Still, stem cell-derived organoids are not the only type of organoid. In fact, there are a wide variety of organoids that are created through different types of cell culture systems. These include 3D bioprinted scaffolds, organ-on-chip, and microfluidics-based 3D cell culture models.
