Multifunctional Microstructured Surfaces by Microcontact Printing of Reactive Microgels

open access: yesAdvanced Functional Materials, EarlyView.
Reactive poly(N‐vinylcaprolactam‐co‐glycidyl methacrylate) microgels are used as functional inks to create surface‐grafted arrays on glass via microcontact printing. The patterns (10–50 µm widths and spacings) enable stable binding and post‐functionalization with dyes and peptides.

Conditioned Media from Mechanically Stimulated Macrophages Upregulate Osteogenic Genes in Human Mesenchymal Stromal Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Bone fracture healing is a complex, timely orchestrated scenario involving multiple cell types and a plethora of cytokines and regulatory factors. To gain further insight, an in vitro model to a) study macrophage polarization under mechanical load in a fibrin hydrogel and b) subsequently assess the effect of conditioned media derived from macrophages ...

Cell Surface Thiol Engineering Mechanoregulates Myogenic Differentiation via the FAK–PI3K–AKT Axis

open access: yesAdvanced Healthcare Materials, EarlyView.
Schematic diagram illustrating how cell surface modification of skeletal muscle progenitor cells through TCEP treatment reveals enhanced cell adhesion, intracellular tension, and myogenesis at 19.66 kPa stiffness, leading to optimal cell fusion. In contrast, no significant changes are observed in the softer (10.61 kPa) or stiffer (49.4 kPa) matrices ...

A Human Neural Tube Model Using 4D Self‐Folding Smart Scaffolds

open access: yesAdvanced Healthcare Materials, EarlyView.
Induced pluripotent stem cells (iPSCs) exhibit features comparable to the inner cell mass of the human embryo. iPSCs are applied to a novel self‐folding 4D‐Neural Tube (4D‐NT) structure that mimics the neurulation process. This 4D‐NT model recapitulates early events of human neural development and represents a platform to explore neurodevelopmental ...

A Novel Core–Shell Hydrogel 3D Model for Studying Macrophage Mechanosensing and Foreign Body Giant Cell Formation

open access: yesAdvanced Healthcare Materials, EarlyView.
The foreign body response (FBR) to biomaterials is primarily driven by macrophages, which often fuse into destructive foreign body giant cells (FBGCs). To address the limited understanding of FBGC formation, a novel microscale core–shell hydrogel 3D model is developed using heterogeneous alginate‐collagen microcapsules with varying stiffness, offering ...

Identification of molecular markers associated to new sources of resistance to the root-knot nematode in cotton : S02T04 [PDF]

open access: yes, 2013
The root-knot nematode (RKN) Meloidogyne incognita is a major constraint in cotton (Gossypium hirsutum L.) production in numerous countries. Control of RKN has been hampered by the lack of options for crop rotation and even more, by the lack of high ...

Vibration‐Mediated Recovery of Irradiated Osteocytes and Their Regulatory Role in Breast Cancer Bone Metastasis

open access: yesAdvanced Healthcare Materials, EarlyView.
Radiotherapy damages bone and disrupts osteocyte function, yet mechanically mediated protection remains largely unexplored. This study demonstrates that low‐magnitude, high‐frequency (LMHF) vibration mitigates irradiated osteocyte apoptosis, restores their ability to regulate breast cancer extravasation, and acts synergistically with radiotherapy to ...

TRPM2 channels mediate ROS-induced actin remodeling and cell migration of prostate cancer cells

open access: yesBMC Cancer
Background Actin remodeling plays important roles in pathophysiological processes such as cancer metastasis and angiogenesis. Reactive oxygen species (ROS) are signaling molecules thought to regulate cell migration by remodeling actin cytoskeleton ...
