Human induced pluripotent stem cells: A disruptive innovation

Area of Science:

• Stem Cell Biology
• Epigenetics
• Genetics

Background:

• The discovery of induced pluripotent stem cells (iPSCs) in 2016 marked a decade of significant advancement.
• Reprogramming differentiated cells into a pluripotent state is achieved through the transient expression of four key transcription factors.
• This process profoundly alters cellular epigenome, transcriptome, and metabolome.

Purpose of the Study:

• To review the diverse applications of induced pluripotent stem cell technology.
• To categorize these applications into nine major areas.
• To highlight the transformative impact of iPSCs in biological research and medicine.

Main Methods:

• Literature review of induced pluripotent stem cell applications.
• Categorization of applications into nine distinct groups.
• Synthesis of findings on iPSC utility in various research and clinical contexts.

Main Results:

• iPSCs serve as models for studying cell fate, pluripotency, human development, and organ physiology.
• They are instrumental in modeling genetic diseases in vitro.
• iPSCs are utilized for cell rejuvenation, drug screening, regenerative medicine, and organogenesis in animals.

Conclusions:

• Induced pluripotent stem cell technology represents a major innovation with far-reaching implications.
• Its applications span fundamental research, disease modeling, and therapeutic development.
• iPSCs are poised to revolutionize regenerative medicine and the creation of human organs.
