They are found on bone surfaces, are multinucleated, and originate from monocytes and macrophages, two types of white blood cells, not from osteogenic cells. …2.1 Bone Formation. Ossification (or osteogenesis) is the process of formation of new bone by cells called osteoblasts. These cells and the bone matrix are the two most crucial elements involved in the formation of bone. This process of formation of normal healthy bone is carried out by two important processes, namely: osteocyte, a cell that lies within the substance of fully formed bone.
