Biomedicines, 2021 One major limitation for the vascularization of bone substitutes used for filling is the presence of mineral blocks. The newly-formed blood vessels are stopped or have to circumvent the mineral blocks, resulting in inefficient delivery of oxygen and ...

Effect of sonic hedgehog/β-TCP composites on bone healing within the critical-sized rat femoral defect [PDF]
, 2013 The creation of entirely synthetically derived bone substitute materials which are as effective as autologous bone grafts is desirable. Osteogenesis involves the concerted action of several proteins within a signaling cascade.

Bone substitutes in vertebroplasty [PDF]
European Spine Journal, 2001 Vertebroplasty--percutaneous cement augmentation of vertebral bodies--is an efficient procedure for the treatment of painful vertebral fractures in osteoporosis. At the present time, polymethylmethacrylate (PMMA) is the only available cement with reports of clinical application and experience.

Substitutes of Structural and Non-Structural Autologous Bone Grafts in Hindfoot Arthrodeses and Osteotomies: A Systematic Review [PDF]
, 2013 Background: Structural and non-structural substitutes of autologous bone grafts are frequently used in hindfoot arthrodeses and osteotomies. However, their efficacy is unclear.

Osteoconductive Microarchitecture of Bone Substitutes for Bone Regeneration Revisited
Frontiers in Physiology, 2018 In the last three decades, all efforts in bone tissue engineering were driven by the dogma that the ideal pore size in bone substitutes lies between 0.3 and 0.5 mm in diameter.

Graphene for Controlled and Accelerated Osteogenic Differentiation of Human Mesenchymal Stem Cells
, 2011 Modern tissue engineering strategies combine living cells and scaffold materials to develop biological substitutes that can restore tissue functions. Both natural and synthetic materials have been fabricated for transplantation of stem cells and their ...

Osteoclast differentiation from human blood precursors on biomimetic calcium-phosphate substrates [PDF]
, 2017 The design of synthetic bone grafts to foster bone formation is a challenge in regenerative medicine. Understanding the interaction of bone substitutes with osteoclasts is essential, since osteoclasts not only drive a timely resorption of the biomaterial,

Preparation, physical-chemical characterisation and cytocompatibility of calcium carbonate cements [PDF]
, 2006 The feasibility of calcium carbonate cements involving the recrystallisation of metastable calcium carbonate varieties has been demonstrated. Calcium carbonate cement compositions presented in this paper can be prepared straightforwardly by simply mixing
