Biomimetic Scaffolds with Dual Gradients of Biological Effectors for Tendon‐to‐Bone Repair

open access: yesAdvanced Healthcare Materials, EarlyView.
The authors have developed a biomimetic scaffold with dual gradients through a diffusion‐driven method. The scaffold features funnel‐shaped microchannels for cell infiltration, while the dual gradients synergetically induce the graded differentiation of mesenchymal stem cells into osteoblasts, chondrocytes, and tenocytes, allowing for a seamless ...

Metaphase Spindle Assembly [PDF]

open access: yesBiology, 2017
A microtubule-based bipolar spindle is required for error-free chromosome segregation during cell division. In this review I discuss the molecular mechanisms required for the assembly of this dynamic micrometer-scale structure in animal cells.

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

open access: yesAdvanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

Bio‐Inspired Artificial Muscle‐Tendon Complex of Liquid Crystal Elastomer for Bidirectional Afferent‐Efferent Signaling

open access: yesAdvanced Materials, EarlyView.
The Muscle–tendon complex (MTC)‐inspired Liquid crystal elastomer (LCE) artificial muscle integrates actuation (efferent) and proprioceptive sensing (afferent) by combining contractile nematic and elastic isotropic LCEs within a single soft structure. Embedded liquid metal channels enable simultaneous Joule heating and real‐time sensing of length and ...

Universal Method for Covalent Attachment of Hydrogels to Diverse Polymeric Surfaces for Biomedical Applications

open access: yesAdvanced Materials, EarlyView.
A universal, reagent‐free strategy is presented for covalently attaching hydrogels to diverse polymeric substrates through reactive oxygen species. The scalable, linker‐free approach enables robust adhesion and broad material compatibility, advancing the fabrication of hybrid solid–hydrogel systems for next‐generation biomedical devices and bioprinting

Mitotic Spindle: Illuminating Spindle Positioning with a Biological Lightsaber [PDF]

open access: yesCurrent Biology, 2018
In metazoans, positioning of the mitotic spindle is controlled by the microtubule-dependent motor protein dynein, which associates with the cell cortex. Using optogenetic tools, two new studies examine how the levels and activity of dynein are regulated at the cortex to ensure proper positioning of the mitotic spindle.
