Mesenchymal stem cells are a promising source for externally grown tissue replacements and patient-specific immunomodulatory treatments. This promise has not yet been fulfilled in part due to production scaling issues and the need to maintain the correct phenotype after re-implantation. One aspect of extracorporeal growth that may be manipulated to optimise cell growth and differentiation is...
"Introduction
In recent years, the clinical application of injectable bone pastes has been increasing because of their benefits including ease to adaptation into irregular-structured defects and injectability suitable to minimally invasive surgery. These advantages are widely advocated to reduce patient complications and health care costs. Here, we successfully developed injectable bone...
"Introduction
Bone is a highly dynamic tissue that undergoes continuous remodeling through lifetime. During this process, two cell types, osteoblasts and osteoclasts, are responsible for bone formation and bone resorption respectively. Mechanical stimuli applied on bone tissue can shift the balance between these two cell populations [1]. Different studies have investigated the impact of the...
"The establishment of vascularisation is one of the current challenges, especially in critically sized bone defects [1,2]. Therefore, the aim of the present work is to develop a biomimetic hydrogel scaffold mimicking the bone osteoid in which proper vasculature is induced in order to maximally stimulate osteogenic regeneration. Thiol-ene step-growth photocrosslinking was herein selected to...
"INTRODUCTION
Understanding the interaction between cells and materials is fundamental to tissue engineering. The scientific community's focus on biomaterial-cell interactions has largely fallen on cellular phenotypes, proteins, and nucleic acids, while molecular mechanisms within cells are often overlooked. However, it is expected that cellular metabolism will be significantly influenced by...
"Tissue engineering proposes an innovative therapeutic approach to support and induce regenerative processes in damaged tissues. Scaffolds should provide a suitable environment for proliferation, differentiation, and maturation of cells and formation of new tissue and blood vessels. Furthermore, scaffolds should be gradually resorbed at a rate commensurate with bone formation. Calcium...
"Surgical repair of large skull bone defects is often performed using patient-specific metallic implants.(1) These implants, however, have poor osseointegration ability, and their life-long fixation is dependent on osteosynthesis screws.(2) It is often suggested that a composite model bone graft substitute could be used to overcome these problems, combining desired properties from individual...
