what do osteoblasts do

Osteoblasts are cells that help bones grow and develop. They form new bones and add growth to existing bone tissue. Osteoblasts are triggered by chemical reactions or hormones when a bone grows or changes. They create and release a mix of proteins called bone matrix. Osteoblasts have three main functions: to form new bones, to strengthen existing bones, and to help repair damaged bones. They work together with osteoclasts, which dissolve old and damaged bone tissue so it can be replaced with new, healthier cells created by osteoblasts
