Cortical‐Hypothalamic Assembloids Uncover the Cortical Regulation of Hypothalamic Responses to Fatty Acid

open access: yesCell Proliferation, EarlyView.
By assembling cortical‐hypothalamic circuits, we show that cortical input protects hypothalamic neurons from fatty acid‐induced damage, which activates PGC1α to boost mitochondrial function. This reveals a cortico‐hypothalamic axis that defends against metabolic stress.

Harnessing Metabolic Priming to Engineer Human Nucleus Pulposus Macromass Overcoming Scalability‐Phenotype Tradeoff

open access: yesCell Proliferation, EarlyView.
Human platelet lysate acts as a metabolic primer for hNPCs, enhancing fatty acid oxidation to drive proliferation while preserving phenotype. This enables construction of high‐quality, large‐size macromasses without necrotic defects, demonstrating exceptional efficacy in repairing degenerated discs in situ and providing a novel paradigm for ...

Dissection of Mitochondrial Function via Chemical Perturbation and Single‐Cell Profiling

open access: yesCell Proliferation, EarlyView.
We establish a systematic framework to dissect mitochondrial function at the module level by combining targeted chemical perturbations with scRNA‐seq. This approach reveals shared and module‐specific programs linking mitochondrial activity to mito‐nuclear communication, stress response, and cell cycle, highlighting the tight coupling between ...

Collagen Type VI Alpha 1 as a Regulator of Redox Homeostasis in Antioxidant‐Enhanced Osteogenesis of Dental Stem Cells

open access: yesCell Proliferation, EarlyView.
Under physiological conditions, NAC activates the PI3K‐AKT‐COL6A1 axis to sustain redox balance and enhance osteogenesis. COL6A1 deficiency, however, compromises this axis, inducing oxidative stress and impairing NAC's osteogenic efficacy. ABSTRACT Alveolar bone injury represents a prevalent clinical challenge in dentistry, for which stem cell‐based ...

Dental Pulp Stem Cell‐Derived Intracellular Vesicles Inhibit OSCC by Delivering PTEN to Suppress PI3K/AKT/mTOR Signalling Pathway

open access: yesCell Proliferation, EarlyView.
DPSC‐IVs suppressed PI3K/AKT/mTOR signalling pathway by delivering PTEN to tumour cells, which reduced the expression of Bcl‐2 and elevated that of Bax. Meanwhile, DPSC‐IVs activated PINK1/Parkin mediated mitophagy, which further raised ROS levels.
