Mini-review highlights YY1's epigenetic regulation for HSC maintenance, revealing insights into aging effects.

The review aims to summarize the roles of YY1 in hematopoietic stem cells and its implications in aging.
Summarized insights from recent studies on YY1 in hematopoiesis.
Discussed YY1's functions as a transcription factor, chromatin organizer, and PcG protein.
Explored mechanistic roles in HSC quiescence, self-renewal, and chromatin organization.
YY1 is essential for maintaining HSC quiescence and self-renewal during both fetal and adult hematopoiesis.
YY1 regulates hematopoiesis through PcG-dependent pathways and higher-order chromatin organization.
Age-associated reductions in YY1 activity contribute to HSC functional impairment and hematopoietic aging.

Wang et al. (2026) studied this question.
