      Timo Stukenkemper, Anica Dose, Maria Caballo Gonzalez, Alexander J.J. Groenen, Sarah Hehir, Vanessa Andrés-Guerrero, Rocio Herrero Vanrell and Neil R. Cameron

      Article first published online: 17 DEC 2014 | DOI: 10.1002/mabi.201400471

      Thumbnail image of graphical abstract

      Nanoparticles from amphiphilic block copolypeptides are loaded with the ocular drug dexamethasone. The block copolypeptides are synthesized by sequential polymerization of benzyl-protected glutamic acid and Z-protected lysine N-carboxyanhydrides (NCAs). Selective deprotection of the benzyl glutamate block yields amphiphilic block copolymers that self-assemble into nanoaprticles in aqueous solution. Drug release is almost complete after 16 d in aqueous solution at 37 °C.

      Article first published online: 14 NOV 2014 | DOI: 10.1002/mabi.201400379

      Thumbnail image of graphical abstract

      Despite years of research, finding cross-linking reactions for hydrogels that are compatible with incorporated proteins is still challenging. The authors, therefore, investigate side reactions between a model protein and methoxypolyethylene glycol functionalized with maleimide, vinyl sulfone, acrylamide, thiol, and furyl moieties. The extent of protein modification was found to depend on the cross-linking agent and the pH during incubation.

      Thumbnail image of graphical abstract

      Nano-sized polymer micelles attract attentions to their biocompatibility and biodegradability in antitumor therapy. However, few investigations focus on exploring the effect of internalized nano-micelles on the cancer cells migration. We demonstrated that amphiphilic PCL–PEG NPs-induced cell migration depended on integrin-FAK-Rho GTPases pathway, which expected to evoke more attentions in the design of drug delivery systems based on polymer micelles.

The modular system allows for facile surface functionalization and property tuning. The novel materials are biocompatible and have tunable degradation rates to non-toxic small molecules and thus are promising for use as synthetic scaffolds for tissue regeneration.

    12. Substrate-induced PC12 Cell Differentiation Without Filopodial, Lamellipodial Activity or NGF Stimulation

      Guillaume Lamour, Sylvie Souès and Ahmed Hamraoui

      Article first published online: 28 OCT 2014 | DOI: 10.1002/mabi.201400323

      Thumbnail image of graphical abstract

      PC12 cells are driven to extend neurites through cell-substrate interactions only, that is, without nerve growth factor (NGF) stimulation. Actin polymerization is destabilized by treating the cells with cytochalasin. As a result the cells are deprived of both filopodia and lamellipodia. However, they extend neurites continuously. This shows that neither filopodia nor lamellipodia are required to trigger substrate-induced neuronal differentiation of PC12 cells.
