The pre‐internalization phase of endocytosis remains poorly characterized at single‐cell levels. Single‐cell pre‐internalization mechanics are investigated using advanced robotic techniques. Cancer cells exhibit biphasic adhesion – rapid initial binding followed by reinforcement – while fibroblasts show gradual engagement.

Polarized cortical tension drives zebrafish epiboly movements [PDF]
The principles underlying the biomechanics of morphogenesis are largely unknown. Epiboly is an essential embryonic event in which three tissues coordinate to direct the expansion of the blastoderm.

The study presents an injectable hydrogel with tunable microporosity to improve mesenchymal stem cell delivery for volumetric muscle loss treatment. Mesenchymal stem cells encapsulated in porous hydrogels significantly promote the spreading, proliferation, and cytokine secretion of mesenchymal stem cells.

Spinal cord injury (SCI) poses significant challenges for regeneration due to a series of secondary injury mechanisms. How to use biomaterial approach to target the failed regeneration after SCI remains a critical challenge. This review systematically evaluates current strategies to optimize biomaterial topographies for neurite outgrowth, axonal ...

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Neural regulation of cardiovascular response to exercise: role of central command and peripheral afferents [PDF]
During dynamic exercise, mechanisms controlling the cardiovascular apparatus operate to provide adequate oxygen to fulfill metabolic demand of exercising muscles and to guarantee metabolic end-products washout.

Engineering Highly Cellularized Living Materials via Mechanical Agitation
A mechanical agitation strategy is developed to engineer highly cellularized living materials, achieving cell densities of up to 1 billion cells per milliliter. By precisely tuning properties such as stiffness and toughness in blood clots, the approach is validated in both in vitro and in vivo studies.

Mortality in patients with acute myocardial infarction is 5–8 % and has not decreased in recent years. One of the causes of death is reperfusion cardiac injury. It is quite obvious that there is an urgent need to develop drugs that can effectively reduce
