Atlas‐Guided CD55‐Enriched Neutrophil Extracellular Vesicles for Complement–Macrophage Modulation in Diabetic Wounds

Advanced Science, EarlyView.
ABSTRACT Diabetic wounds are characterized by persistent inflammation and impaired immune resolution, yet the therapeutic translation of single‐cell atlases into rational immunomodulatory strategies remains limited. Here, integration of diabetic‐wound single‐cell transcriptomic datasets identifies a neutrophil subpopulation enriched in cluster of ...

Effects of CO2 enrichment on microstructure and ultrastructure of two species of freshwater green algae

, 2002
order to investigate the morphological response of freshwater green algae to elevated CO2 concentration, Chlamydomonas reinhardtii Dang and Scenedesmus obliquus Kutz were cultured with enriched CO2, and their microstructure and ultrastructure were ...

AKAP1 Protects Retinal Ganglion Cells and Preserves Vision by Improving Mitochondrial and Synaptic Health in Glaucomatous Neurodegeneration

Advanced Science, EarlyView.
Intravitreal AAV2‐mediated AKAP1 restoration enhances mitochondrial fusion and biogenesis, improves bioenergetic capacity, and preserves mitochondrial integrity in glaucomatous RGCs. AKAP1 stabilizes presynaptic structure, maintaining synaptic protein expression, and limiting complement‐associated neuroinflammation.

Acinar‐Derived Organoids Reveal Stage‐Specific Control of Acinar Plasticity

Advanced Science, EarlyView.
An acinar‐derived organoid system maintains adult pancreatic acinar identity ex vivo, converts it along an ordered acinar‐to‐ductal‐like trajectory, and then partially restores it. Each transition carries its own signal requirement, with EGF/EGFR initiating conversion and a staged glucocorticoid–IGF1R switch driving redifferentiation.

Long‐Term Expandable Periosteal Organoids Reconstruct a Functional Regenerative Niche That Support Hematopoietic Stem Cell Maintenance and Bone Repair

Advanced Science, EarlyView.
A robust periosteal organoid system enables long‐term expansion while preserving native cellular heterogeneity. These organoids recapitulate functional niche environments, support hematopoietic stem cell maintenance, and attenuate aging‐associated decline ex vivo.

Donor‐Cell Senescence Redirects PINK1‐Marked Mitochondrial Cargo From Mitophagy to Microvesicle Transfer Through SUMO3‐Stabilized HSPA9

Advanced Science, EarlyView.
ABSTRACT Extracellular vesicle therapies have been developed for tissue repair, but how donor‐cell senescence reshapes vesicle‐mediated mitochondrial transfer remains unclear. Here, we show that senescent adipose‐derived stem cells (ADSCs) redirect damaged mitochondria into microvesicles (MVs), converting protective vesicles into pro‐degenerative ...

Engineering a Bioelectronic Hybrid Heart with Integrated Sensing and Electrical Modulation

Advanced Science, EarlyView.
A bioelectronic hybrid heart is engineered by integrating iPSC‐derived cardiomyocytes, a decellularized cardiac scaffold, a cell‐laden ECM coating, and a flexible electronic mesh. The embedded electrodes enable real‐time recording of spontaneous electrical activity and localized stimulation, allowing controlled pacing and modulation of activation ...

Arhgef1 Deletion Disrupts Early Cortical Neurogenesis via PAK1 Overactivation and Causes Motor Dysfunction in Adulthood

Advanced Science, EarlyView.
ARHGEF1 plays a pivotal role in both embryonic cortical neurogenesis and adult motor function. During early development, it governs genesis of deep‐layer cortical neurons by negatively regulating RAC1/CDC42‐PAK1‐Cofilin signaling. In adulthood, ARHGEF1 is important for the maintenance of neuronal morphology and activity in the motor cortex, ensuring ...
