The developing fields of bone tissue engineering and regenerative medicine have identified skeletal defects, such as degenerative disorders of the lumbar spine, as attractive translational targets. Bone tissue engineering comprises cells, biomaterials, which should preferably be biodegradable, and biologics (biological stimuli to trigger differentiation of stem cells). Mesenchymal stem cells (M...

As life expectancy increases, malfunction or loss of tissue caused by injury or disease leads to reduced quality of life in many patients at significant socioeconomic cost. Even though major progress has been made in the field of bone tissue engineering, present therapies, such as bone grafts, still have limitations. Current research on biodegradable polymers is emerging, combining these struct...

severe hepatic failure accounts for many deaths and raises medical costs each year worldwide. currently, liver transplantation is the most common therapeutic option for patients with end-stage chronic liver disease. due to decrease in the number of organ donors, many in need of transplantation continue to remain on the waiting list. hepatic tissue engineering is a step toward alleviating the ne...

Tissue engineering is becoming consolidated in the biomedical field as one of the most promising strategies in tissue repair and regenerative medicine. Within this discipline, bone tissue engineering involves the use of cell-loaded porous biomaterials, i.e. bioscaffolds, to promote bone tissue regeneration in bone defects or diseases such as osteoporosis, although it has not yet been incorporat...

Background: engineering new bone tissue with cells and a synthetic extracellular matrix represents a new approach for the regeneration of mineralized tissues compared with the transplantation of bone (autografts or allografts). Methods: in this study, to mimic the mineral and organic component of natural bone, hydroxapatite (HA) and gelatin (GEL) composite scaffolds were prepared. The raw mater...

Engineering craniofacial bone tissues is challenging due to their complex structures. Current standard autografts and allografts have many drawbacks for craniofacial bone tissue reconstruction; including donor site morbidity and the ability to reinstate the aesthetic characteristics of the host tissue. To overcome these problems; tissue engineering and regenerative medicine strategies have been...
