Osseous Tissue Function

Precedent has been set with the clinical application of bone marrow-derived adult stem cells; however there is evidence that stem cells isolated from the cardiac tissue itself may provide a more relevant source for tissue engineering strategies. Hence, the engineered tissue construct is an artificial scaffold populated with living cells and signalling molecules. Bone, or osseous tissue, is a hard, dense connective tissue that forms most of the adult skeleton, the support structure of the body. Each bone contains two types of osseous tissue (bone tissue): (1) Compact bone is very dense and solid, and it is always found on the surface of the bone. Inflammation can interfere with the function of osteoblasts, so consuming omega-3 fatty acids, in the diet or in supplements, may also help enhance production of new osseous tissue. Along with osseous tissue, the bones also include marrow, blood vessels, nerves, and epithelium, which covers the surface of. Your surgeon might take bone from your hips, legs, or ribs to perform the graft. Spongy bone makes up most of the structure of short, flat, and irregular bones and is also found at the epiphyses of long bones.
