Derived from various adult somatic cell types via the introduction of four specific transcription factors: OCT3/4, SOX2, KLF4, and c-MYC, induced pluripotent stem cells (iPSCs) have the ability to differentiate into derivatives of all three germ layers and show great potential in fields ranging from regenerative medicine to disease modeling.https://www.creative-biolabs.com/stem-cell-therapy/teratoma-formation-assays-for-ipsc.htm
