ANATOMY

Detailed explanation-1: -Osteoblasts are cells responsible for the secretion and deposition of bone morphogenetic proteins (BMPs) into the extracellular matrix during bone formation.

Detailed explanation-2: -Osteoblasts originate from immature mesenchymal stem cells, which can also differentiate and give rise to chondrocytes, muscle, fat, ligament and tendon cells (Aubin and Triffitt, 2002). Mesenchymal stem cells undergo several transcription steps to form mature osteoblast cells.

Detailed explanation-3: -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.
