Distribution of Elements along the Rachis of Cycas micronesica Leaves: A Cautionary Note for Sampling Design

Horticulturae, 2019
Cycas micronesica K.D. Hill trees on the island of Yap were used to determine the influence of position along the leaf rachis on macro- and micro-nutrient concentrations and how leaf age affected the results.

Simplifying cancer: binary pan-cancer superclasses stratified by opposite YAP/TEAD effects

Molecular & Cellular Oncology, 2021
The inherent complexity of cancer complicates treatment. Identifying higher-order principles that govern cancer biology can circumvent this problem and pinpoint broadly applicable treatment options.

Mechanoregulatory Effects of Cell‐Scale Microwells on Epithelial Cell Phenotype

Advanced Functional Materials, EarlyView.
In small polycaprolactone microwells, A549 epithelial cells span well edges, in contrast to cells growing on flat substrates. Focal adhesion sites (yellow) concentrate at topographic boundaries, while cytoskeletal tension (magenta stress fibers) is transmitted to the nucleus (blue), reducing nuclear sphericity.

The Floor‐Ceiling‐Chip, or 2 × 2D = Pseudo‐3D—Approaching 3D Cell Morphology and Organization between Two Opposing 2D Substrates with Cell‐Adhesive Protein Micropatterns

Advanced Healthcare Materials, EarlyView.
Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...

Dynamic Modulation of the Microenvironment Promotes Functional Maturation of Engineered Tissues

Advanced Healthcare Materials, EarlyView.
Engineered tissues lack the dynamic microenvironment of native tissues. A biocompatible, diffusible small molecule to dynamically modulate tissue microenvironments during maturation is used. Timing‐dependent modulation yields distinct outcomes, producing thicker, more native‐like blood vessels, stronger and more mature cardiac tissues, and optimized ...

Oxygen and ROS Delivery for Infected Wound Healing and Future Prospects

Advanced Healthcare Materials, EarlyView.
Bacterial infection is a major driver of delayed wound healing and postsurgical readmissions; with rising antibiotic resistance, solid peroxide–releasing biomaterials offer sustained delivery of ROS/O2 for antimicrobial control and microenvironmental modulation.

Common Signatures of Altered Gene Regulation and Invasiveness of Different Breast Cancer Cell Lines after Matrix Interface Crossing

Advanced Healthcare Materials, EarlyView.
Interface transmigration reprograms triple‐negative breast cancer cells, triggering a shared switch toward more aggressive and invasive phenotypes. Using a collagen I interface model, this study identifies shared transcriptional changes involving proliferation, chromatin remodeling, and DNA repair pathways.

Controllable Dynamic Mechanical Cell Stimulation using Magnetically Actuated Artificial Cilia

Advanced Healthcare Materials, EarlyView.
This paper introduces a platform based on magnetic artificial cilia for providing controllable dynamic mechanical stimulation to single cells, suitable for investigating large cell populations and enabling live cell imaging. Proof‐of‐principle experiments show that cell morphology is strongly influenced by the artificial cilia, that cellular forces can
