Induced Pluripotent Stem Cells (iPSCs) are a type of stem cell generated by reprogramming adult cells, such as skin or blood cells, to possess characteristics similar to embryonic stem cells. This process typically involves introducing specific key reprogramming genes (OCT4, KLF4, SOX2, cMYC, NANOG, and LIN28) into the adult cells, enabling them to regain pluripotency.
