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.

Photochemical Regiodivergent Functionalization of Quinolines with Aryl Ketones

Advanced Science, EarlyView.
A photocatalytic system‐controlled approach enables regiodivergent C2‐ and C4‐functionalization of quinolines with aryl ketones by optimizing aryl thiol photocatalysts and formate reductants. Using ortho‐(isopropoxycarbonyl)thiophenol with excess formate facilitates C4‐dearomatization, yielding bridged 1,3‐oxazepanes. In contrast, meta‐(methoxycarbonyl)

Photo‐Induced Stepwise Liquid Crystal Phase Transition Enabled by Hydrazone Photoswitch

Advanced Science, EarlyView.
A judiciously designed bistable hydrazone photoswitch enables a photo‐induced stepwise “order‐disorder” phase transition in liquid crystals. The linear‐to‐bent isomerization disrupts molecular packing, allowing precise tuning of phase transition temperatures.

Biomimetic Nanoplatform for Fibrosis Remodeling and Anti‐PD‐1 Potentiation via Cu+/Ca2+ Ion Dysregulation and TGF‐β Inhibition in PDAC

Advanced Science, EarlyView.
A biomimetic nanoplatform (RPm@CC‐LY) remodels fibrotic stroma via sustained TGF‐β inhibition, triggers oxidative stress and apoptosis through Cu+‐mediated Fenton chemistry and Ca2+ overload, and reprograms macrophages and dendritic cells to boost CD8+ T cell infiltration.
