ANATOMY

Detailed explanation-1: -The primary role of osteoblasts is to lay down new bone during skeletal development and remodelling. Throughout this process osteoblasts directly interact with other cell types within bone, including osteocytes and haematopoietic stem cells.

Detailed explanation-2: -Osteoblasts. Osteoblasts are the main cells responsible for bone formation. These cells secrete extracellular matrix proteins such as type I collagen, osteopontin, osteocalcin and alkaline phosphatase; multiple osteoblasts interact with one another to create a unit of bone known as an osteon3.

Detailed explanation-3: -Osteoblasts are cells responsible for the secretion and deposition of bone morphogenetic proteins (BMPs) into the extracellular matrix during bone formation.

Detailed explanation-4: -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.
