Advanced Healthcare Materials, EarlyView.Chamber‐specific decellularized extracellular matrices (ECMs) were developed, preserving native proteomic profiles of ventricular and atrial myocardium. These innate biochemical cues differentially modulate cardiomyocyte subtypes to drive engineered heart tissue development and function, highlighting the importance of incorporating regional ECM cues in

Motor units in a fast‐twitch muscle of normal and dystrophic mice.
The Journal of Physiology, 1983 Isometric contractions of motor units, isolated functionally by ventral root splitting were recorded from extensor digitorum longus muscles of normal and dystrophic mice of the strain C57BL/6J dy2J/dy2J. Motor unit tetanic tension was significantly lower and both time to peak tension and to half‐relaxation of the twitch were significantly prolonged in ...

Advanced Healthcare Materials, EarlyView.This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

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 ...

Enhancing Maturation of Human Neuromuscular Organoids via Electrical Stimulation
Advanced Science, EarlyView.A framework for on‐demand and non‐invasive exposure of human neuromuscular organoids (NMOs) to electrical stimuli is established to promote their maturation. The robustness and effectiveness of different stimulation regimes are evaluated via thorough characterization of organoid tissue structure and contraction capacity. Chronic electrical stimulation,

Slow sodium channel inactivation in rat fast‐twitch muscle.
The Journal of Physiology, 1987 1. Voltage‐clamp Na+ currents (INa) were measured in rat fast‐twitch fibres using the loose‐patch‐clamp technique. Changes in the conditioning membrane potential produced slow changes in the peak INa elicited by short test depolarizations, due to a slow inactivation process. 2. Inactivation was increased by application of steady depolarizing potentials

Advanced Science, EarlyView.A minimally invasive optical window enables stable, long‐term imaging of peripheral nerves in vivo at single‐axon resolution. Dynamic processes of degeneration, regeneration, and cellular remodeling are visualized across multiple time scales within the same nerve region, providing a unique platform to study a variety of anatomical and molecular events ...

Cycling Cross-Bridges Contribute to Thin Filament Activation in Human Slow-Twitch Fibers
Frontiers in Physiology, 2020 It has been shown that not only calcium but also strong binding myosin heads contribute to thin filament activation in isometrically contracting animal fast-twitch and cardiac muscle preparations. This behavior has not been studied in human muscle fibers
