The cell responsible for bone resorption, or breakdown, is the osteoclast. They are found on bone surfaces, are multinucleated, and originate from monocytes and macrophages, two types of white blood cells, not from osteogenic cells.

What cells are produced by osteogenic cells?
4.2. Osteoblasts are the bone cells derived from osteochondral progenitor cells that form the bone through a process called ossification. Osteoblasts result in the formation of new layers of bone by producing a matrix that covers the older bone surface.
Are osteocytes derived from osteogenic cells?
OSTEOCYTES are cells inside the bone. They also come from osteoblasts. Some of the osteoblasts turn into osteocytes while the new bone is being formed, and the osteocytes then get surrounded by new bone.
What are osteogenic cells derived from?
Osteogenic Cells Derived From Embryonic Stem Cells Produced Bone Nodules in Three-Dimensional Scaffolds.
What cells found in bones are descended from osteogenic cells?
2.1. The Sources, Differentiation Pathways and Stemness Potency of Tissue-Derived Osteogenic Cells. Adult bone marrow is known to contain mesenchymal stem cells, which are able to differentiate into a range of cell lineages, forming mesenchymal tissues such as bone, cartilage and muscle.
Are osteogenic cells stem cells?
According to current hypothesis, cells of the osteogenic lineage, which includes both osteoblasts and chondroblasts, are derived from a stromal stem cell in the postnatal organism. That there exist osteogenic precursors in association with the soft, fibrous tissue of the marrow stroma is well established.
Do osteogenic cells undergo mitosis?
One of the key characteristics of osteoblasts, osteocytes, and osteoclasts is that they do not undergo mitosis. Osteogenic cells, however, can undergo mitosis. Osteogenic cells are cells that differentiate into osteoblasts. Once differentiated, the osteogenic cells can no longer undergo mitosis.
Are osteogenic cells Osteoprogenitor cells?
The osteoblast, osteoclast, osteocyte, and osteoprogenitor bone cells are responsible for the growing, shaping, and maintenance of bones. Bone consists of four types of cells: osteoblasts, osteoclasts, osteocytes, and osteoprogenitor (or osteogenic) cells.
Where are osteogenic cells?
Immature osteogenic cells are found in the deep layers of the periosteum and the marrow. When they differentiate, they develop into osteoblasts. The dynamic nature of bone means that new tissue is constantly formed, while old, injured, or unnecessary bone is dissolved for repair or for calcium release.
Where do osteogenic cells reside?
In mature bones, osteocytes and their processes reside inside spaces called lacunae (Latin for a pit) and canaliculi, respectively. Osteocytes are simply osteoblasts trapped in the matrix that they secrete.
What are the 3 primary cells that make up bone and what is their function?
There are three types of cells that contribute to bone homeostasis. Osteoblasts are bone-forming cell, osteoclasts resorb or break down bone, and osteocytes are mature bone cells.
Where do you find osteogenic cells quizlet?
Osteogenic cells are mitotically active stem cells found in the periosteum; some daughter cells can turn into osteoblasts while others stay as stem cells.
Which of the following stimulates osteoclast activity?
Parathyroid hormone stimulates osteoclast activity, meaning the answer is d).
What are Chondrogenic cells?
Chondroblasts are progenitor cells that secrete the extracellular matrix (ECM), while chondrocytes are involved in nutrient diffusion and matrix repair. Both cell types are required to form cartilage.
What are Osteoprogenitor osteogenic cells cells?
Osteoprogenitor cells are the ‘stem’ cells of bone, and are the source of new osteoblasts. Osteoblasts, lining the surface of bone, secrete collagen and the organic matrix of bone (osteoid), which becomes calcified soon after it has been deposited. As they become trapped in the organic matrix, they become osteocytes.
What are osteoclast cells?
Osteoclasts are the cells that degrade bone to initiate normal bone remodeling and mediate bone loss in pathologic conditions by increasing their resorptive activity. They are derived from precursors in the myeloid/monocyte lineage that circulate in the blood after their formation in the bone marrow.
