Artificial Cornea Substitute Based on Hydrogel Skeletons with Natural Stromal Hierarchical Structure and Extracellular Matrix for Sutureless Transplantation

Advanced Science, EarlyView.
Humanized corneal stroma‐like adhesive patches (HCSPs) are developed for lamellar keratoplasty and corneal perforation repair. HCSPs exhibit histological, optical, and biomechanical characteristics similar to those of the natural cornea, with improved wet tissue adhesion, anti‐degradation, and anti‐swelling capabilities compared to conventional tissue ...

Generation of sutured manifolds [PDF]

arXiv
Given a compact, oriented, connected surface $F$, we show that the set of connected sutured manifolds $(M,\gamma)$ with $R_{\pm}(\gamma)\cong F$ is generated by the product sutured manifold $(F,\partial F)\times[0,1]$ through surgery triads. This result has applications in Floer theories of $3$--manifolds.

Delivery of Human iPSC‐Derived RPE Cells in Healthy Minipig Retina Results in Interaction Between Photoreceptors and Transplanted Cells

Advanced Science, EarlyView.
Human induced pluripotent stem cell‐derived retinal pigment epithelial (hiPSC‐RPE) cells, cultured on a clinically relevant PDLLA scaffold, are transplanted into immunosuppressed minipigs. The study demonstrates the viability, integration, and preservation of RPE‐specific features without gliosis or neuroinflammation, supporting their potential as a ...

A Molecularly Defined Medullary Network for Control of Respiratory Homeostasis

Advanced Science, EarlyView.
The dynamic interplay between central respiratory chemoreceptors and the respiratory central pattern generator is essential for maintaining stable respiratory rhythm and patterns, particularly during sleep. This study offers novel insights into the anatomical, molecular, and functional characteristics of a medullary network involving the nucleus ...

Targeting Splenic Myeloid Cells with Nanobiologics to Prevent Postablative Pancreatic Cancer Recurrence via Inducing Antitumor Peripheral Trained Immunity

Advanced Science, EarlyView.
Using a preclinical pancreatic cancer model, we identified that tumor progression restructures splenic immunity via myeloid cell expansion. MDCa@RBC‐Alipo nanobiologics were engineered to epigenetically and metabolically reprogram splenic myeloid cells, alleviating post‐ablation immunosuppression.

UGDH Lactylation Aggravates Osteoarthritis by Suppressing Glycosaminoglycan Synthesis and Orchestrating Nucleocytoplasmic Transport to Activate MAPK Signaling

Advanced Science, EarlyView.
Lactylation of UDP‐glucose dehydrogenase (UGDH) represses its enzymatic activity and causes glycosaminoglycans loss. In addition, UGDH lactylation facilitates its interaction with chromosome region maintenance 1 (CRM1) and promotes the nucleocytoplasmic transport.

KLF1 Promotes Cardiomyocyte Proliferation and Heart Regeneration Through Regulation of Wnt/β‐Catenin Signaling Pathway

Advanced Science, EarlyView.
In KLF1‐on (neonatal and Klf1 overexpression hearts) models, KLF1 regulates Wnt/β‐catenin signaling pathway and the expression of cell proliferation‐related genes via transcriptional and epigenetic mechanisms, which induces cardiomyocyte proliferation and cardiac regeneration in mice after myocardial infarction.

Label‐Free Dual‐Modal Photoacoustic/Ultrasound Localization Imaging for Studying Acute Kidney Injury

Advanced Science, EarlyView.
This work develops a 3D label‐free photoacoustic/super‐resolution ultrasound imaging system as a comprehensive non‐invasive tool for acute kidney injury (AKI) study. This technique visualizes the intricate structure of renal microvessels and provides critical physiological insights, including renal hemodynamics and oxygenation.
