Interactions of intestinal epithelial cells with bacterial extracellular products

The enteric microflora represents one of the densest microbial populations in the biological world; as a consequence, the intestinal immune system is constantly exposed to high concentrations of antigenic materials. One of the major frontline defences in

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

Advanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Effects of Extracellular Matrix Constituents on the Attachment of Human Oral Epithelial Cells at the Titanium Surface

, 1998
This in vitro study attempts to delineate the role of extracellular matrix (ECM) constituents at the epithelial tissue-implant interface. To know which ECM constituents have a beneficial influence on the behavior of epithelial cells, the attachment ...

Intimate Interaction Between Nucleic Acid and Conjugated Polymers in Organic Electrochemical Transistors Enables Ultrasensitive Biomarker Detection

Advanced Materials, EarlyView.
The intimate interaction between negatively charged RNA molecules and conjugated polymers in organic electrochemical transistors (OECTs) in aqueous electrolytes is investigated. It demonstrates that RNA binding reduces the volumetric capacitance of the polymer channel, enabling the development of an ultrasensitive biosensing platform capable of ...

Nocturnal Intraocular Pressure Monitoring With a Soft Contact Lens Sensor for Glaucoma Management

Advanced Materials, EarlyView.
A soft contact lens sensor enables continuous, noninvasive monitoring of nocturnal intraocular pressure (IOP) under closed‐eye sleep conditions. By integrating a highly compliant inductive–capacitive circuit onto a commercial lens, the device achieves record sensitivity and stable performance.

Embryoid body attachment to reconstituted basement membrane induces a genetic program of epithelial differentiation via jun N-terminal kinase signaling

, 2010
Embryonic stem (ES) cells are derived from early stage mammalian embryos and have broad developmental potential. These cells can be manipulated experimentally to generate cells of multiple tissue types which could be important in treating human diseases.

Cell Adhesion by Design: Engineering Tissue Culture Scaffolds With Adhesion Cues

Advanced Materials Interfaces, EarlyView.
ABSTRACT In scaffold‐based tissue engineering, the matrix should provide adequate adhesion cues for cell attachment, spreading, and function. Given the multitude of adhesion receptors and the diversity of scaffolds, there are many approaches to render scaffolds adhesive, even though they are not all equivalent.

Epithelial Attachment and Downgrowth on Dental Implant Abutments-A Comprehensive Review

, 2014
The soft tissues around dental implants are enlarged compared with the gingiva because of the longer junctional epithelium and the hemidesmosonal attachments are fewer, suggestive of a poorer quality attachment.

Multilayered Digital Microfluidic Chip for Cell‐Based Assays

Advanced Materials Interfaces, EarlyView.
A multilayered digital microfluidic (mDMF) chip architecture is introduced to improve throughput and robustness in cell‐based assays. By multilayering electrode components and dielectric layers on glass, this design significantly reduces actuation voltage, maintains reliability, and enables expansion of the operational area with minimum current leakage.

Use of Percoll Density Gradients for Studying the Attachment of Bacteria to Oral Epithelial Cells

, 1988
An assay for studying the attachment of bacteria to oral epithelial cells has been developed which utilizes Percoll density gradient centrifugation to separate bacteria and epithelial cells. 3H-thymidinelabeled bacteria were incubated with suspensions of
