Additive‐Manufactured, Multifunctional Bioreactor Technology for Dynamic Culture of 3D Bioprinted Tissue Models

Advanced Materials Technologies, EarlyView.
We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

Multimodal Imaging Reveals Rapid Catecholamine Uptake and Release by Neutrophils

Advanced Science, EarlyView.
We show that immune cells (neutrophils) synthesize, uptake, and store catecholamine neurotransmitters such as dopamine or adrenaline. They also release them in response to specific stimuli (serotonin), which we directly visualize using fluorescent nanosensors. We further demonstrate that catecholamines affect neutrophil functions (NETosis) and platelet

A Wireless 3D Magneto‐Mechanical Stimulation Platform Drives In Situ Chondrogenic Commitment of Endogenous MSCs

Advanced Science, EarlyView.
An intracellular magneto‐mechanical platform utilizing MSC‐targeted nanomotors is developed. After intra‐articular delivery, these nanomotors target endogenous BMSCs and are actuated within lysosomes to execute trans‐planar rotational‐bouncing motions under a rotating‐fluctuating 3D magnetic field, generating amplified mechanical stimulation.

Dynamic changes and transcriptome analyses reveal the microfilament skeleton response to water stress in thalli of Neopyropia yezoensis inhabiting the intertidal zone

Plant Stress
The microfilament (MF) cytoskeleton, present in all eukaryotic cells, is not only essential for fundamental cellular processes but also is important in sensing and transducing external signals in response to various developmental cues and abiotic ...

Systemic Nanomechanical Single‐Cell Profiling Reveals Mechanophenotype Transitions Under Therapeutic Perturbation

Advanced Science, EarlyView.
Single‐cell mechanomics demonstrates that pharmacological perturbation changes cytoskeletal and cortical structure, suppressing cancer cell invasiveness. By integrating atomic force microscopy (AFM)‐based cortical measurements with stimulated emission depletion (STED)‐resolved adhesion and cytoskeletal organization, this approach identifies nanoscale ...

Basolateral Membrane-associated 27-kDa Heat Shock Protein and Microfilament Polymerization [PDF]

Journal of Biological Chemistry, 1997
The in vivo activity of the 27-kDa heat shock protein, a barbed-end microfilament capping protein, may be localized to the plasma membrane. To investigate this putative association, bovine endothelial cells expressing the human wild type or a mutant nonphosphorylatable 27-kDa heat shock protein were subjected to subcellular fractionation and immunoblot

Cytoskeleton–Membrane Uncoupling in Duchenne Muscular Dystrophy: Implications for Newborn Screening and Early Protection

Cytoskeleton, EarlyView.
ABSTRACT The cytoskeleton of striated muscle integrates force transmission, mechanotransduction, and sarcolemmal stability through coordinated networks of sarcomeres, costameres, and intermediate filaments. Together, these systems establish mechanical continuity between the contractile apparatus, the sarcolemma, and the extracellular matrix.
