摘要

Craniomaxillofacial bone marrow mesenchymal stromal cells (BMSCs) retaining neural crest–derived neurogenic niche is driven by lineage memory and niche homeostasis. Elucidating how the neurogenic potential is maintained is critical for neurological health. Here, we explored a neural crest-like progenitor niche in BMSCs with high neurogenic and proliferative capacity by single-cell transcriptomics. In which, ANKRD1 is a pivotal regulator sustaining the neurogenic reservoir. Importantly, ANKRD1 expression in this niche declines with aging and lineage commitment, coinciding with its redistribution from a diffuse nucleoplasmic pattern to perinuclear enrichment along the nuclear lamina and loss of neural potential. Mechanistically, ANKRD1 preserves neurogenic capacity by directly binding super-enhancers of neural marker genes (SOX2, NESTIN) and maintaining open chromatin architecture. Critically, neuron-targeted ANKRD1 delivery rescues spatial memory deficits in aged mice. These findings establish ANKRD1 as a therapeutically tractable regulator that sustains neurogenic chromatin reservoirs to support neurocognitive resilience, opening avenues to counter cognitive aging.
