Supplement-free induction of macrophage polarization solely through the topography of materials is an auspicious strategy but has so far significantly lacked behind the efficiency and intensity of media-supplementation based proto-cols. We investigated Melt-Electrowriting (MEW) for the fabrication of fibrous 3D scaffolds made from poly(ε-caprolactone) (PCL) and advanced the precisely defined...
INTRODUCTION: Mesoporous bioactive glass nanoparticles (MBG NPs) have received a significant amount of interest for their potential to treat cancer cells with high drug loading capacity and excellent stability, providing a controlled drug release platform into the malignant tumor [1]. Although enhanced permeability and retention (EPR) effects allow MBG NPs to accumulate at tumor sites, the...
The reconstruction and replacement of musculoskeletal tissues have been extensively investigated in the last decades. Trauma injuries and degenerative diseases are the most common causes reported worldwide. Stem cells play an important role in tissue regeneration and have been successfully applied in musculoskeletal research, especially due to the low self-repair capability of tendons,...
"Introduction
Biodegradable polymeric scaffolds face a growing use in tissue engineering. However, changes in material properties during degradation can impact drastically the scaffold durability and therefore the efficiency of tissue reconstruction. Few studies focus on approaches allowing the prediction of the scaffold lifetime, while there is a need for strategies using accelerated testing...
"Introduction:
Highly porous biodegradable scaffolds made of polycaprolactone (PCL) and ceramic designed as three-dimensional (3D) guiding structures with rectilinear filling to facilitate bone regeneration have successfully been translated from preclinical studies into clinics as part of a scaffold-guided bone tissue engineering (SGBTE) concept. However, advances in 3D printer technology now...
Inflammation is a protective response to damaged tissue and foreign bodies, such as biomaterials, and is usually considered to be negative. More recently, however, the active anti-inflammatory, pro-regenerative role of various mediators and inflammatory cytokines from immune cells have become widely recognised. In particular, macrophages play an essential mediating role in modulating...
The main risk factors for aseptic loosening and implant failure are wear and corrosion of metal implants. Despite a passive oxygen layer forming on many implant materials, electrochemical reactions can occur [1]. Oxidation and reduction reactions take place, resulting in a constant exchange of electrons and ions between the metal and the surrounding fluid [2]. The release of metal ions in...
Although the secretome of mesenchymal stem cells (MSCs) has a great potential to be used in CNS regenerative therapies, tissue derived MSCs are a limited source which often need to be surgically harvested and present intrinsic donor variability. Induced pluripotent stem cells (iPSCs) conversely, can be easily generated and highly expanded from accessible somatic cell sources and differentiated...
