Nuclear-Mitochondria Crosstalk in Senescent Adipose-Derived Stem Cells

Abstract

Adipose-derived stem cells (ADSCs) are central regulators of adipose tissue homeostasis and regenerative capacity. Accumulating evidence indicates that aging and obesity profoundly impair ADSC function, through progressive mitochondrial dysfunction and disrupted mitochondrial–nuclear communication. Emerging studies reveal that defects in nuclear–mitochondrial crosstalk constitute a key driver of ADSC senescence and adipose tissue aging. In this review, we synthesize recent advances in understanding the mitochondrial mechanisms underlying ADSC aging, with particular emphasis on how mitochondrial dysfunction reshapes stem cell fate decisions, metabolic plasticity, and inflammatory signaling within aged adipose niches. We further highlight mitochondria targeting therapeutic strategies that hold promise for reversing ADSC senescence. Collectively, this framework positions mitochondrial regulation as a unifying axis for ADSC rejuvenation, offering new opportunities to restore adipose tissue homeostasis and mitigate age-related metabolic dysfunction.
