As embryonic stem cells become pluripotent, they may cause tumor development when injected into a host. Therefore, researchers are focusing heavily on the therapeutic potential of tissue-specific stem cells (adult stem cells) without resultant tumor formation. Adult stem cells can proliferate for a limited number of generations and are restricted to certain cell types (multipotent). Mature tissue cell types in mammals cannot be intrinsically dedifferentiated or transdifferentiated to adult stem cells. Hence, the technology of induced pluripotent stem cells (iPSCs) for reprogramming adult somatic cells was introduced in 2006, ushering in a new era in adult stem cell research. Although iPSCs have been widely used in the field, the approach has several limitations: instability of the reprogramming process, risk of incomplete reprogramming, and exposure to transgenes integrated into the cell genome. Two years before the introduction of the iPSC technique, the synthetic small molecule 2,6-disubstituted purine, called reversine, was introduced. Reversine can induce the dedifferentiation of committed cells into multipotent progenitor-type cells by reprogramming and converting adult cells to other cell types under appropriate stimuli. Thus, it can be used as a chemically induced multipotent cell agent to overcome the limitations of iPSCs. Also, as an alternative therapeutic approach for treating obesity, it can be used to generate beige cells by browning white adipocytes. While reversine has the potential to act as an anti-cancer agent, this review focuses on its role in differentiation, dedifferentiation, and transdifferentiation in somatic cells.
