Tumor Microenvironment On‐A‐Chip and Single‐Cell Analysis Reveal Synergistic Stromal–Immune Crosstalk on Breast Cancer Progression

open access: yesAdvanced Science, EarlyView.
Using a 3D tumor microenvironment (TME)‐on‐a‐chip model, tumor–stromal–immune crosstalk in triple‐negative breast cancer is studied, revealing the TME's combinatorial effect on cancer progression. Integrating single‐cell transcriptomic analysis demonstrates metabolic reprogramming via the kynurenine pathway, highlighting the complex TME cellular ...

Biomimetic MOF Nanocarrier‐Mediated Synergistic Delivery of Mitochondria and Anti‐Inflammatory miRNA to Alleviate Acute Lung Injury

open access: yesAdvanced Science, EarlyView.
A biomimetic MOF nanocarrier for macrophage‐targeting delivery of both mitochondria and anti‐miR‐127 is designed with an aim to revitalize macrophages and remold the inflammatory microenvironment for treating acute lung injury. By leveraging the macrophages‐targeting property and pH‐responsiveness, ZIF‐8 nanocarriers facilitated efficient delivery of ...

Biological Reinforced Concrete for Cartilage Repair With 3D Printing

open access: yesAdvanced Science, EarlyView.
Inspired by concrete rebar structures in engineering, the concept of biological reinforced concrete uses 3D‐printed ultrafine fiber networks (UFNs) as biodegradable “biorebars”, hybrid biohydrogels as “biocement”, and stem cells as “bioactive aggregates” to fabricate biomimetic cartilage.

Stabbing non-piercing sets and face lengths in large girth plane graphs [PDF]

open access: yesarXiv
We show that a non-piercing family of connected planar sets with bounded independence number can be stabbed with a constant number of points. As a consequence, we answer a question of Axenovich, Kie{\ss}le and Sagdeev about the largest possible face length of an edge-maximal plane graph with girth at least $g$.
