Answer:
The osteoblasts, which should have been building the new bone
Explanation:
Osteoblast are the cells that build bones by secreting the extracellular matrix for bone tissue. These cells secrete components such as collagen fibres and inorganic electrolytes that together make the matrix of bone tissue. Absence or inactivity of these cells could prevent the formation of new bone after fracture. Hence, doctors should target osteoblasts.
