Surface and bulk stresses drive morphological changes in fibrous microtissues

Mahmut Selman Sakar, Erik Mailand, Nikolaos Bouklas

Engineered fibrous tissues consisting of cells encapsulated within collagen gels are widely used three-dimensional (3D) in vitro models of morphogenesis and wound healing. While cell-mediated matrix remodeling that occurs within these scaffolds has been ex ...

Podosomes, But not the Maturation status, Determine the Protease-Dependent 3D Migration in human Dendritic cells

Romain Guiet

Dendritic cells (DC) are professional Antigen-Presenting Cells scattered throughout antigen-exposed tissues and draining lymph nodes, and survey the body for pathogens. Their ability to migrate through tissues, a 3D environment, is essential for an effecti ...

Focal release of neurotrophic factors by biodegradable microspheres enhance motor and sensory axonal regeneration in vitro and in vivo

Silvestro Micera, Daniel Santos

Neurotrophic factors (NTFs) promote nerve regeneration and neuronal survival after peripheral nerve injury. However, drawbacks related with administration and bioactivity during long periods limit their therapeutic application. In this study, PLGA microsph ...

Bio-engineered collagen-fibrin scaffolds for enhancing urological tissue regeneration

Elif Vardar

Urological tissue engineering offers alternative solutions for congenital and acquired diseases of the urinary tract, which may require reconstructive surgery. It evolves to overcome complications, which might be encountered after surgery. Therefore, tissu ...

The Nano-Scale Mechanical Properties of the Extracellular Matrix Regulate Dermal Fibroblast Function

Jean-Jacques Meister, Boris Hinz, Lara Buscemi Estefanell, Josiane Angèle Charlotte Smith-Clerc

Changes in the mechanical properties of dermis occur during skin aging or tissue remodeling and affect the activity of resident fibroblasts. With the aim to establish elastic culture substrates that reproduce the variable softness of dermis, we determined ...

The Mechanical Environment Modulates Intracellular Calcium Oscillation Activities of Myofibroblasts

Boris Hinz, Adriano Garonna, Lysianne Follonier Castella

Myofibroblast contraction is fundamental in the excessive tissue remodeling that is characteristic of fibrotic tissue contractures. Tissue remodeling during development of fibrosis leads to gradually increasing stiffness of the extracellular matrix. We pro ...

Hydrogels for Urinary Tract Tissue Engineering

Lionel Ambroise Micol

Several urinary tract disorders, such as hypospadias or bladder cancer, require reconstructive surgery to preserve the patient's quality of life and at times even save their life. The current available surgical treatments, involving grafts from other tissu ...

Hypoxia Impairs Skin Myofibroblast Differentiation and Function

Boris Hinz, Giorgio Pietramaggiori

Ischemic wounds are characterized by oxygen levels lower than that of healthy skin ( hypoxia) and poor healing. To better understand the pathophysiology of impaired wound healing, we investigated how switching from high ( 21%) to low ( 2%) oxygen levels di ...

Compressed collagen gel: a novel scaffold for human bladder cells

Florian Maria Wurm, Peter Frey, Jeffrey Alan Hubbell

Collagen is highly conserved across species and has been used extensively for tissue regeneration; however, its mechanical properties are limited. A recent advance using plastic compression of collagen gels to achieve much higher concentrations significant ...

The effect of matrix characteristics on fibroblast proliferation in 3D gels

Matthias Lütolf, Jeffrey Alan Hubbell, Simone Rizzi, Martin Ehrbar

Engineering synthetic hydrogels on a molecular basis to introduce natural features that are important in instructing cell behavior is becoming increasingly crucial in biomaterial-based approaches for regenerative medicine and in cell biology to study cell– ...
