Psoriasis and Leukocyte Chemotaxis.

Journal of Investigative Dermatology, 1987
Transepidermal migration of leukocytes, with resultant formation of microscopic or macroscopic sterile subcorneal pustules is a phenomenon characteristically noted in psoriasis and related sterile pustular dermatoses. It is natural to assume the presence of potent neutrophil chemotactic substances in the subcorneal portion of the lesional epidermis ...

Mesenchymal Stem Cell‐Inspired Microneedle Platform for NIR‐responsive Immunomodulation and Accelerated Chronic Wound Healing

Advanced Materials, EarlyView.
The research demonstrates a Mesenchymal Stem Cell‐inspired microneedle platform (MSCi@MN) that addresses chronic diabetic wounds by combining MSC‐derived extracellular nanovesicles (NV)–DNA conjugates in microneedle tips with photothermal MXene in the patch layer.

An Injection‐Molded Modified Silicone Rubber for Cancer‐on‐Chip Applications

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This study describes the characterization and application of an injection‐molded functionalized PDMS fluidic insert for the commercially available Micronit system. Modified PDMS can accommodate cell culture and is able to covalently bind proteins for long‐lasting coatings under flow‐conditions.

Evaluation of Cell‐Extracellular Vesicle Interaction Using a Microfluidic Microsystem (CellExoChip)

Advanced Materials Technologies, EarlyView.
A new microfluidic platform, the CellExoChip, reveals how cancer cells interact with exosomes to influence metastasis. This device isolates cancer cells and tracks their uptake exosomes and secretion of their exosomes in response to other exosomes. Lung cancer cells are showed preferentially absorb and respond to their own exosomes—hinting at a hidden ...

Chemotaxis in reverse [PDF]

The Journal of Cell Biology, 2007
A cell polarity switch controls whether cells rush toward an attractive chemical or shift into reverse when they encounter something repulsive, according to Keizer-Gunnink et al. on page 579. They show that the status of phospholipase C (PLC) sets up the polarity axis for directional movement.

One‐Step Covalent Biofunctionalization of Tubular Constructs Enabled by Surface‐Embedded Radicals

Advanced Materials Technologies, EarlyView.
Uniform covalent biofunctionalization of tubular constructs is achieved in one step using surface‐embedded radicals generated by a novel plasma immersion ion implantation (PIII) technology. This scalable, solvent‐free technology advances bioengineered tubes for tissue engineering and implant applications.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

COP5/HKR1 changes ciliary beat pattern and biases cell steering during chemotaxis in Chlamydomonas reinhardtii

Scientific Reports
This study investigates the control of ciliary beat patterns during ammonium chemotaxis in the model ciliate microalga Chlamydomonas reinhardtii. Screening the chemotaxis response of mutant strains with ciliary defects revealed that a strain lacking CAV2,
