An Overview on Promising Somatic Cell Sources Utilized for the Efficient Generation of Induced Pluripotent Stem Cells

Area of Science:

• Stem cell biology
• Regenerative medicine
• Cellular reprogramming

Background:

• Human induced Pluripotent Stem Cells (iPSCs) hold significant promise for research and therapeutic applications.
• Fibroblasts, a traditional source for iPSC generation, present limitations impacting reprogramming efficiency.
• The choice of somatic cell source critically influences iPSC reprogramming efficiency, kinetics, and quality.

Purpose of the Study:

• To review promising, easily accessible somatic cell sources for human iPSC generation.
• To highlight the advantages of using non-invasive or minimally invasive cell sources.
• To discuss the potential for generating patient-specific iPSCs.

Main Methods:

• Exploration of various somatic cell types for reprogramming potential.
• Focus on keratinocytes, urine cells, and peripheral blood mononuclear cells.
• Review of reprogramming factor combinations and their impact.

Main Results:

• Keratinocytes, urine cells, and peripheral blood mononuclear cells are identified as promising sources for iPSC generation.
• These sources facilitate non-invasive or minimally invasive isolation.
• iPSCs derived from these sources demonstrate improved reprogramming efficiency and kinetics.

Conclusions:

• Easily accessible somatic cells offer efficient and faster generation of bona fide iPSCs.
• Patient-derived iPSCs from these sources provide ethical and clinical benefits.
• This knowledge aids in developing strategies for safe and efficient patient-specific iPSC generation.
