Stem cells track and maintain their cellular specialization state through epigenetic mechanisms
Extensive scientific literature confirms that stem cells rely heavily on epigenetic mechanisms—such as DNA methylation, histone modifications, and chromatin remodeling—to track, preserve, and maintain their cellular specialization and self-renewal states.
The retrieved papers consistently demonstrate that epigenetic mechanisms (including histone modifications, DNA methylation, and chromatin remodeling complexes) are fundamental for maintaining stem cell identity, quiescence, potency, and self-renewal across various tissue types (e.g., hematopoietic, skeletal, embryonic, and germline stem cells). Because all relevant evidence strongly supports the claim without contradiction, the verdict is SUPPORTED.
