The occurrence and development of induced pluripotent stem cells

Area of Science:

• Stem Cell Biology
• Regenerative Medicine
• Epigenetics

Background:

• The discovery of induced pluripotent stem cells (iPSCs) revolutionized regenerative medicine.
• Reprogramming somatic cells into iPSCs is primarily achieved using Oct3/4, Sox2, Klf4, and c-Myc (OSKM) transcription factors, known as Yamanaka factors.
• Significant advancements have enhanced the efficiency of iPSC generation and therapeutic applications.

Purpose of the Study:

• To review the historical discovery and evolution of induced pluripotent stem cell (iPSC) technology.
