Induced pluripotent stem cells (iPSCs) refer to a type of stem cell directly generated using reprogramming techniques from multipotent adult stem cells. Therefore iPSCs gained a lower level of differentiation and could present themselves as pluripotent. Although the only pluripotent cells in nature are embryonic stem cells, researchers acquired the knowledge, skills, and the power necessary to reinvert the natural differentiation and specialization process of a cell and thus artificially obtain a pluripotent cell from a multipotent cell.
