Bone remodeling is a process in which old or damaged bone is removed by osteoclasts and replaced with new bone formed by osteoblasts. Osteoclasts, bone-resorbing cells, originate from hematopoietic stem cells (HSCs) [4–8] and degrade bone via secretion of acid and proteolyticThe blood-forming stem cells in red bone marrow can multiply and mature into three significant types of blood cells, each with its own job: ... These cells originate from hematopoietic stem cells ... osteoblast, large cell responsible for the synthesis and mineralization of bone during both initial bone formation and later bone remodeling. Osteoblasts form a closely packed sheet on the surface of the bone, from which cellular processes extend through the developing bone. They arise from the differentiation of osteogenic cells in the ... Recent findings. Langerhans cells (LCs) originate pre-natally and may endure throughout life, independently of bone marrow derived precursors.
