Bioinspired engineered microenvironments provide cells with a holistic “instructive niche” that offers the adequate entourage for cellular control both in space and time. Biomaterials provides essentially surface signals. We hypothesise that volume characteristics of biomaterials have a negligible influence on cell-behaviour and new tissue formation as compared with interfacial mechanical,...
Vasculature plays an essential role in skin physiology and its architecture and function are altered in aged and diseased skin. Quite remarkably, papillary and reticular dermis show very distinct extracellular matrix (ECM) and vascularization. Furthermore, fibroblasts freshly isolated from their native microenvironment have different gene expression patterns, morphology and proliferation rate....
Introduction: Atopic dermatitis (AD) is a chronic inflammatory and common skin disorder that is frequently associated with other atopic diseases such as allergic rhinitis and asthma. The immunopathogenesis of AD is a complex process, as both innate and adaptive immune systems are involved in the development of eczema in those patients. Keratinocytes, mast cells, dendritic cells, and T cells,...
Introduction:
Stromal vascular fraction (SVF) cells, isolated from adipose tissue are an abundant easily accessible stromal cell source for bone tissue engineering. These characteristics make them a good alternative to bone marrow derived mesenchymal stem cells (BM-MSCs). Previous studies from our group provided a proof-of-concept that Adipose-derived Stromal Cells (ASCs), resulting from the...
Our newly developed self-feeding hydrogels with enzyme-empowered degradation capacity have demonstrated high biological performance in-vitro and in-vivo as a novel self-maintained and biocompatible 3D scaffold1. Photo-crosslinkable platelet lysates (PL)-based hydrogels have exhibited to support distinct human-derived cell cultures owing to their high content of bioactive molecules, such as...
Background:
Urethral reconstruction is performed in patients with urethral strictures or for correction of congenital disorders. In most instances, foreskin or buccal mucosa flaps are used in these surgeries. However, complications may occur due to limited availability of tissue. In the future, tissue engineering (TE) might offer alternative solutions as it enables a detailed design to...
Introduction
Tendon injuries are common in equine athletes. Tissue healing occurs via biomechanically inferior scar tissue deposition, often resulting in re-injury. This is mediated, in part, by excessive proinflammatory cytokine release in the acute stages following injury. Stimulating equine tenocytes with interleukin 1 beta (IL-1β) alters tendon-associated and extracellular matrix...
Introduction: Fecal incontinence has a high impact on patient quality of life. Available treatments based on surgical and non-surgical approaches range from change in diet, to bowel training or sacral nerve stimulation, none of which represent a long-term solution. Novel therapies are emerging that aim to regenerate the sphincter muscle and, therefore, restore continence. These approaches...
Introduction
The subcutaneous space is an attractive alternative site for engineering vascular networks, since it provides relatively easy accessibility, minimal invasiveness, and potentially high transplant capacity. However, it’s also a poorly vascularized site that often fails to achieve the level of vascularization necessary to maintain function of thick grafts.1 Here, we patterned our...
