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.

Large Oncosomes Induce Pro‐Metastatic Stromal‐Myeloid Reprogramming

Advanced Science, EarlyView.
Large oncosomes systemically reprogram bone marrow mesenchymal stem cells through innate nucleic acid sensing, driving inflammatory and immunosuppressive remodeling that supports a metastasis‐permissive bone marrow environment, revealing a novel tumor‐host communication axis in cancer. ABSTRACT Bone metastasis can be facilitated by systemic remodeling,

SpaCut: Transcript‐Aware Morphology Fusion for Robust Cell Segmentation in Subcellular Spatial Transcriptomics

Advanced Science, EarlyView.
Subcellular spatial transcriptomics enables high‐resolution mapping of gene expression within tissues, but accurate cell segmentation is essential for assigning transcripts to individual cells. We present SpaCut, a deep learning framework that integrates transcriptomic features with nucleus‐guided morphological information to precisely delineate cell ...

BRCA1 Mutation‐Recognizing Tetrahedral Framework Nucleic Acid Nanoplatform Enables Coordinated PARP/WEE1 Inhibition and STING‐Associated Antitumor Immunity in Ovarian Cancer

Advanced Science, EarlyView.
BRCA1 mutation‐responsive FBOA‐tFNA selectively recognizes mutant transcripts and coordinates reduction‐responsive intracellular delivery of olaparib and adavosertib, amplifying DNA damage and weakening G2/M checkpoint protection. These effects are accompanied by STING‐associated immune activation and stronger antitumor immunity, while sequential anti ...

Binding of bacterial secondary messenger molecule c di-GMP is a STING operation

, 2013
Initial skirmishes between the host and pathogen result in spillage of the contents of the bacterial cell. Amongst the spillage, the secondary messenger molecule, cyclic dimeric guanosine monophosphate (c di-GMP), was recently shown to be bound by ...

Molecular MRI Reveals Macrophage‐Enriched Peritumoral Immune Remodeling After Incomplete Ablation in Liver Cancer

Advanced Science, EarlyView.
Incomplete microwave ablation (iMWA) induced a spatially organized, macrophage‐rich immunosuppressive tumor microenvironment (TME) in orthotopic VX2 liver tumors. Molecular MRI enhanced with europium‐doped very small superparamagnetic iron oxide nanoparticles (Eu‐VSOP) noninvasively visualized this remodeling, showing preferential nanoparticle ...

Topology‐Driven X‐Shaped DNA as a cGAS Stimulator to Promote Dendritic Cell Activation and Antitumor Vaccine Efficacy

Advanced Science, EarlyView.
X‐shaped DNA promotes multivalent cGAS assembly and enhances cGAS‐STING signaling. When conjugated with antigenic peptides, the resulting X‐DNA‐based peptide vaccine promotes dendritic cell activation, antigen presentation, and antitumor T‐cell responses.
