Tuning the Testicular Microenvironment for Enhancing Human Sertoli Cells Maturation and Functionality In Vitro

Advanced Healthcare Materials, EarlyView.
An in vitro testicular model is developed by generating connective tissue equivalents from human dermal fibroblast‐derived microtissues and coupling them with human Sertoli cells or human Sertoli cell spheroids. This engineered microenvironment supports Sertoli cell maturation and functionality, providing a promising platform for studying human ...

Packed for Ossification: High‐Density Bioprinting of hPDC Spheroids in HAMA Toward Endochondral Ossification

Advanced Healthcare Materials, EarlyView.
Human periosteum‐derived cell spheroids bioprinted at high density within a hyaluronic acid matrix promote fusion and hypertrophic cartilage formation in vitro. Early encapsulation enhances spheroid interaction and matrix maturation, generating scalable cartilage templates intended for endochondral bone regeneration.

CORE: Cholesterol Altered Lipid Nanoparticles for Splenic Expression of mRNA Payloads

Advanced Healthcare Materials, EarlyView.
In this paper researchers introduce CORE LNPs, a new class of lipid nanoparticles engineered to redirect mRNA expression away from the liver and into the spleen, a key immune organ. By combining chemical design with computational tools, they created cholesterol analogs that enable precise spleen‐targeted expression, providing greater applications for ...

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

Advanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Statistical Evaluation of a Ribosome-Only Protocell in Prebiotic Environments: Implications for the RNA World Hypothesis

The RNA World hypothesis posits that RNA-based systems, such as ribosomes, could sustain early life without additional molecular support. We test this by simulating a protocell composed solely of a modern ribosome (large and small subunits, ~4,500 nt rRNA, excluding mRNA, tRNA, proteins, or other elements) in hydrothermal vents (80 ± 15°C, pH 6.0 ± 0.5,

Seta‐Inspired Mechano‐Intelligent Janus Bandage with Coordinated Adhesion–Contraction for Minimizing Scarring

Advanced Materials, EarlyView.
We developed a bioinspired mechano‐intelligent Janus bandage (MIB) with a hydrophobic flat exterior and a hydrophilic interior featuring gecko‐mimicking wedged microstructures, fabricated via micromolding and anisotropic plasma treatment. The MIB dynamically synchronizes adhesion and contraction, enabling precise force modulation.

Coupled Molecular Dynamics and Kinetic Modeling of RNA Replication Refute RNA World Hypothesis, Supporting Synergistic Matter World Model(Estimated Calculation Simulation)

The RNA World Hypothesis (RWH) posits that RNA alone initiated life, serving as both genetic material and catalyst. However, RNA’s chemical instability, poor catalytic efficiency, and high mutation rates challenge its evolvability. The Matter World Hypothesis (MWH) proposes that life emerged from synergistic interactions among RNA, DNA, peptides ...

Microsecond-to-Millisecond Simulations and Kinetic Modeling Refute RNA World Hypothesis, Supporting Synergistic Matter World Model(Estimated Calculation Simulation)

The RNA World Hypothesis (RWH) posits that RNA alone initiated life, acting as both genetic material and catalyst. However, RNA’s chemical instability and limited catalytic efficiency challenge this view. The Matter World Hypothesis (MWH) proposes that life emerged from synergistic interactions among RNA, DNA, peptides, lipids, and catalysts in diverse

A Cryoprotectant‐Compatible Nanoporous Platform for Stable and Scalable Delivery of Biopharmaceuticals

Advanced Materials, EarlyView.
A cryoprotectant‐compatible nanoporous platform enables ambient‐stable and scalable delivery of gene editing therapeutics. By combining hierarchical pore architecture with optimized lyophilization chemistry, the system preserves Cas9‐RNP activity post‐freeze‐drying.
