Introduction Axonal plasticity is strongly related to neuronal development as well regeneration. It was recently demonstrated that active mechanical tension, intended an extrinsic factor, a valid contribution the modulation of axonal plasticity. Methods In previous publications, our team validated “nano-pulling” method used apply forces developing axons isolated primary neurons using magnetic nanoparticles (MNP) actuated by static fields. This found promote axon growth and synaptic maturation. Here, we explore use nano-pulling factor regeneration in tissue explant. Results Whole dorsal root ganglia (DRG) were thus dissected from mouse spinal cord, incubated with MNPs, then stretched. We particles able penetrate ganglion become localised both somas sprouting axons.

Biological structures have evolved to very efficiently generate, transmit, and withstand mechanical forces. These biological examples inspired engineers for centuries led the development of critical insights concepts. However, progress in engineering also raises new questions about structures. The past decades seen increasing study failure engineered due repetitive loading, its origin processes such as materials fatigue. Repetitive loading is experienced by some neurons, example peripheral nervous system. This perspective, after briefly introducing concept fatigue, aims discuss potential effects based on our knowledge cellular responses stresses. A particular focus discussion are stress axons their cytoskeletal Furthermore, we highlight difficulty imaging these promise microscopy techniques. identification repair mechanisms paradigms underlying long-term stability an exciting emerging topic biology well a source inspiration engineers.

Abstract Reconstructing the nigrostriatal pathway is one of major challenges in cell replacement therapies for Parkinson's disease due to lack enabling technologies capable guiding reinnervation dopaminergic precursors transplanted into substantia nigra toward striatum. This paper examines nano‐pulling, as a technology enable remote manipulation axonal growth. Specifically, an organotypic model consisting co‐cultures and striatum developed demonstrate that when cortical neural progenitors are nigra, nano‐pulling can guide enhance elongation projections To provide additional evidence, induced pluripotent stem cell‐derived progenitor neurospheres generated it shown induce guided growth promote maturation their processes. Altogether, this study demonstrates potential emerging technique directed within central nervous system.

Myofibers are highly specialized contractile cells of skeletal muscles, and dysregulation myofiber morphogenesis is emerging as a contributing cause myopathies structural birth defects. Myotubes the precursors undergo dramatic morphological transition into long bipolar myofibers that attached to tendons on two ends. Similar axon growth cones, myotube leading edges navigate toward target form cell-cell connections. The process guidance connects myotubes with correct tendons, orients morphology overall body plan, generates functional musculoskeletal system. Navigational signaling, addition mass volume, identification common events in guidance, but surprisingly, mechanisms regulating these not completely overlapping axons. This review summarizes strategies have evolved direct predetermined tendon highlights key differences between guidance. association pathways developmental disorders also discussed.
