A human osteoblast is a type of cell that plays an important role in the process of bone formation. Osteoblasts are responsible for the synthesis and mineralization of the extra-cellular matrix to form new bones. Osteoblasts come from mesenchymal precursor cells and create a continuous pool of progenitor cells that give rise to all bone-forming cells.

The main purpose of human osteoblasts is to help in the formation and maintenance of bones. Osteoblasts secrete components which form a natural scaffold for minerals such as calcium and phosphate to be deposited, thereby providing strength to the newly formed bone. Additionally, they also secrete several growth factors which promote angiogenesis (the formation of blood vessels) necessary for providing adequate oxygen and nutrients for bones during their development and maintenance.

Human osteoblasts play an important role in creating healthy bones by forming a natural scaffold on which minerals like calcium and phosphate can be deposited, thereby giving strength to these bones. Additionally, the growth factors secreted by osteoblasts encourage angiogenesis required for delivering adequate oxygen and nutrients into newly formed bones. This increases their rate of recovery after fractures or other injuries.

Human osteoblast cells are primarily produced via mesenchymal stem cell differentiation inside the bone marrow or periosteum (the outer surface layer). This process consists of several steps where multi-lineage progenitor cells transform into pre-osteoblastic cells before maturing into fully functional human osteoblast cells with specialized gene expression patterns and associated functions.

An immature, or pre-osteoblast, looks similar to other connective tissue cell types under magnification due to its lack of specialized cellular features at this stage in its maturation progression. However, microscopic examination reveals subtle changes in its nucleus size as well as cytoplasmic processes when compared with adjacent fibroblastic or adipogenic precursors upon which it was derived from prior differentiation stages.

Osteopontin (OPN), BMPs (Bone Morphogenetic Proteins)and Wnts (wingless related integration site proteins) are three major signaling molecules known to regulate different aspects related tohuman osteoblast production and maturation progressions both directly through gene inhibition or activation processes as well as indirectly via inflammatory cytokine release from immune/inflammatory agents within nearby micro-environments found in bone marrow environments.

Osteoplastic extracellular matrix (ECM) interactions provide structural support for humanosteoblasts allowing them grow attached along surfaces inside typical bone marrow compartments where they feed off surrounding microenvironment resources obtained from various neighboring collagen fibers located within ECMs composed mainly hyaluronic acid molecules along with other glycan saccharides along with specifically patterned glycoproteins known collectively as proteoglycans.
