What are osteoblasts?

Osteoblasts are specialized cells that are primarily responsible for the formation of bone. They play a crucial role in the processes of bone growth, healing, and remodeling by synthesizing and secreting the components of the bone matrix, including collagen and other proteins. As osteoblasts become embedded in the matrix they produce, they mature into osteocytes, which are essential for maintaining bone tissue. This function is vital for maintaining the structural integrity of bones and ensuring they can withstand the stresses and strains experienced during daily activities. Their role is contrasted with osteoclasts, which are the cells that break down bone, underscoring the balance of bone formation and resorption required for healthy skeletal maintenance.
