An Organ‐on‐Chip Platform for Strain‐Controlled, Tissue‐Specific Compression of Cartilage and Mineralized Osteochondral Interface to Study Mechanical Overloading in Osteoarthritis

Advanced Healthcare Materials, EarlyView.
A mechanically active OsteoChondral Unit (OCU)‐on‐Chip platform mimicking the OCU's functional anatomy and the strain gradient across the osteochondral interface is presented. Upon compartment‐specific hyperphysiological compression, the model replicates mechanisms observed in osteoarthritis (OA) progression, such as calcium crystal accumulation ...

Porous Decellularized Nerve Grafts Facilitate Recellularization and Nerve Regeneration in a Rat Model of Critical Long‐Gap Peripheral Nerve Injury

Advanced Healthcare Materials, EarlyView.
A decellularized nerve graft (DNG) is modified to generate a porous DNG (PDNG). The PDNG is used to repair a 30‐mm peripheral nerve injury (PNI) defect, and is compared with isograft, serving as the standard, and DNG, a widely used alternative. The result shows that PDNG facilitated nerve regeneration in long‐gap PNI, evidenced by better‐aligned axonal

Cysteine Cathepsin Activity Regulation by Glycosaminoglycans

BioMed Research International, 2014
Cysteine cathepsins are a group of enzymes normally found in the endolysosomes where they are primarily involved in intracellular protein turnover but also have a critical role in MHC II-mediated antigen processing and presentation.

Mechanical Reinforced and Self‐healing Hydrogels: Bioprinted Biomimetic Methacrylated Collagen Peptide‐Xanthan Gum Constructs for Ligament Regeneration

Advanced Healthcare Materials, EarlyView.
Readily UV‐curing and self‐healing methacrylated collagen peptide (COPMA) hydrogels are developed with tunable mechanical properties. As the interpenetrating network between COPMA and xanthan gum (XG), COPMA‐XG bioinks show improved mechanical properties, printability, and stability, compared to COPMA or XG.

Microscopically Adaptable Bioink Guide Cell Compartmentalization toward Morphogenesis of a Functional Vasculature‐Like System

Advanced Healthcare Materials, EarlyView.
Contractile vasculatures are fabricated through a one‐step bioprinting strategy. The adaptable microenvironment provided by ECM‐mimicking bioink triggers cell sorting and compartmentalization of endothelial cells and vascular smooth muscle cells toward a histological configuration by focal adhesion kinase‐mediated upregulation of cell adhesion and ...

The Structural Elucidation of Glycosaminoglycans [PDF]

, 2008
There is accumulating evidence of the importance of linear polysaccharides in modulating biological phenomena in both the normal and the diseased states. This layer of regulation results from interactions between polysaccharides and other biomolecules, such as proteins, at the cell-extracellular matrix interface.

Biomimetic Cell Membrane‐Coated Scaffolds for Enhanced Tissue Regeneration

Advanced Materials, EarlyView.
This review examines the development and use of cell membrane‐coated scaffolds in tissue engineering. Bioinspired phospholipid and glycocalyx coatings enhance anti‐fouling, anti‐thrombogenic, and selective molecular recognition properties. Native cell membrane coatings further support cell‐specific interactions, immune modulation, and reduced bacterial
