WebbOsteoblasts and osteocytes are both cells that help you grow and maintain bones. Osteoblasts are the cells that form new bones and grow and heal existing bones. They release bone matrix that turns proteins into new tissue. Bone matrix fills in gaps and spaces in your existing bone tissue. Osteocytes are cells inside mature bone tissue. WebbThe osteoblasts try to compensate but the new bone they lay down is weak and brittle and therefore prone to fracture. While some people with Paget’s disease have no symptoms, others experience pain, bone fractures, and bone deformities ( Figure 6.3.9 ).
