Polystyrene nanoplastics disrupt pancreatic immune–endocrine homeostasis by promoting MHC‐I‐associated dendritic cell activation and inflammatory crosstalk with β cells. This immune remodeling drives β‐cell dedifferentiation, impairs insulin secretion, and aggravates metabolic dysfunction, revealing a previously unrecognized immunometabolic mechanism ...

Programmable Paracrine‐Mimetic Microneedle System for Temporal Regulation of Cardiac Repair
Temporal signaling is encoded into a programmable paracrine‐mimetic microneedle patch via tris(2,2'‐bipyridyl)dichlororuthenium(II) hexahydrate/sodium persulfate‐tuned hydrogel microparticles that deliver TGF‐β, IGF‐1, and VEGF over phase‐matched 7‐, 14‐, and 28‐day windows.

IGF-I and IGF-II in relation to colorectal cancer
Recent data suggest that the IGF system plays an important role in the pathogenesis of several forms of human cancer, and there is evidence that IGFs acting in an autocrine and paracrine manner may also affect colorectal cancer risk. We have conducted a case-control study on the island of Crete, Greece, to examine the potential relation between ...

Matrix stiffness directs mesenchymal stem cell lineage commitment through PIEZO1‐dependent activation of the SP1/STC2 pathway. Stiff matrices favor osteogenesis and suppress adipogenesis, whereas the loss of PIEZO1 function impairs early bone formation. STC2 retains lineage‐regulatory activity even when PIEZO1 is inactive.

AARS1 drives PI3K–AKT–mTOR‐dependent glycolysis in bladder cancer, promoting lactate accumulation, increased lactylation, H3K27la enrichment at the HK2 promoter, and HK2 transcription. HK2 reinforces glycolysis, sustaining a metabolic–epigenetic program associated with tumor progression, recurrence, and metastasis.

Using genetic code expansion, we engineered vascularized human cerebral organoids (vhCOs) with microglia‐like cells and blood‐brain barrier features. vhCOs recapitulate neurovascular interactions, regional identities, and neuronal subtypes resembling the fetal brain.

Multi‐Tissue Crosstalk Regulating Meniscus Healing Under Inflammation and Physiological Loading
Using a novel Meniscus‐on‐a‐chip (MoC) model integrated with a meniscus‐specific bioreactor, this study investigated the roles of multi‐tissue crosstalk that regulates injury, healing, and degeneration of the meniscus injury under inflammation and pathophysiological loading.

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.
