Organoids: technology refining, current applications and future directions

Organoids are derived from pluripotent stem cells or tissue stem cells, progenitor cells, or differentiated cells from healthy or diseased tissues (e.g., tumors). Numerous organoid engineering strategies have been tested to support the culture, growth, proliferation, differentiation, and maturation of organoids. A variety of organoids and organoid-on-chips have also been constructed to reflect real environments of human and mouse organs. Currently, four major areas of potential application for o
