Abstract
This review article discusses the epigenetic regulation of quiescent stem cells. Quiescent
stem cells are a rare population of stem cells that remain in a state of cell cycle
arrest until activated to proliferate and differentiate. The molecular signature of
quiescent stem cells is characterized by unique epigenetic modifications, including
histone modifications and deoxyribonucleic acid (DNA) methylation. These modifications
play critical roles in regulating stem cell behavior, including maintenance of quiescence,
proliferation, and differentiation. The article specifically focuses on the role of
histone modifications and DNA methylation in quiescent stem cells, and how these modifications
can be dynamically regulated by environmental cues. The future perspectives of quiescent
stem cell research are also discussed, including their potential for tissue repair
and regeneration, their role in aging and age-related diseases, and their implications
for cancer research. Overall, this review provides a comprehensive overview of the
epigenetic regulation of quiescent stem cells and highlights the potential of this
research for the development of new therapies in regenerative medicine, aging research,
and cancer biology.
