Tissue-Restricted Stem Cells as Starting Cell Source for Efficient Generation of Pluripotent Stem Cells: An Overview

Area of Science:

• Stem cell biology and regenerative medicine.
• Epigenetic reprogramming and cellular differentiation.

Background:

• Induced pluripotent stem cells (iPSCs) are crucial for disease modeling, drug discovery, and cell therapy.
• The generation of iPSCs involves reprogramming somatic cells using specific transcription factors.
• Optimizing iPSC generation efficiency and kinetics requires identifying ideal starting cell populations.

Purpose of the Study:

• To review promising tissue-restricted stem cells for efficient iPSC generation.
