Blood bone marrow in a process called hematopoiesis, which includes erythropoiesis, the production of red blood cells; and myelopoiesis, the production of white blood cells and platelets. During childhood, almost every human bone produces red blood cells; as adults, red blood cell production is limited to the larger bones: the bodies of the vertebrae, the breastbone (sternum), the ribcage, the pelvic bones, and the bones of the upper arms and legs. In addition, during childhood, the thymus gland, found in the mediastinum, is an important source of T lymphocytes. The proteinaceous component of blood (including clotting proteins) is produced predominantly by
Generative tissue and has a unique cellular and biochemical make-up that make it distinct from other tissues of the body. gTissue was discovered through research in the fields of Tissue Engineering and Regenerative Medicine and first created as a dense connective tissue between the brain and skull during the repair of canine dura mater. It has since been successfully created in humans for a wide range of clinical applications in soft tissue healing and repair. Essentially, the gTissue is created by implanting certain types of non-inflammatory ECM biomaterials that are adopted by the host, including repopulation with host cells and blood vessels,
