Bone tissue engineering is a field that aims to create functional bone tissue using a combination of stem cells, biomaterials, and growth factors. This approach is used to regenerate damaged or lost bone tissue, commonly caused by injuries, diseases, or aging. Researchers in this area focus on developing new biomimetic materials and scaffolds that mimic the natural bone matrix, as well as optimizing culture conditions to promote the differentiation and proliferation of stem cells into bone-forming cells. The ultimate goal of bone tissue engineering is to provide patients with innovative treatments for bone defects and fractures, ultimately improving their quality of life and long-term outcomes.
