Bone exclusively with red marrow or hematopoietic marrow, but as the child ages the hematopoietic fraction decreases in quantity and the fatty/ yellow fraction called marrow adipose tissue (MAT) increases in quantity. In adults, red marrow is mostly found in the bone marrow of the femur, the ribs, the vertebrae and pelvic bones. Bone is a metabolically active tissue composed of several types of cells. These cells include osteoblasts, which are involved in the creation and mineralization of bone tissue, osteocytes, and osteoclasts, which are involved in the reabsorption of bone tissue. Osteoblasts and osteocytes are derived from osteoprogenitor cells, but
Soft tissue growth at cellular level. Growth and remodeling have a major role in the cause of some common soft tissue diseases, like arterial stenosis and aneurisms and any soft tissue fibrosis. Other instance of tissue remodeling is the thickening of the cardiac muscle in response to the growth of blood pressure detected by the arterial wall. There are certain issues that have to be kept in mind when choosing an imaging technique for visualizing soft tissue ECM components. The accuracy of the image analysis relies on the properties and the quality of the raw data and, therefore, the choice of the
